GPT-4o: последний взгляд
ОглавлениеЧто сделал GPT-4o
Валидация от GPT-4oОтвет GPT-4o
Это вторая часть цикла «Исследование возможностей ИИ писать код». И она особенная: GPT-4o, о котором пойдёт речь, уже успели снять с полок, а затем вернуть под давлением жалоб пользователей, но это лишь временная передышка. Модель официально заменена GPT-5 и в любой момент она снова может исчезнуть. Поэтому то, что вы читаете, это скорее исторический снимок работы с устаревшей моделью.
ИИ развивается быстрее, чем я успеваю писать статьи, но это не повод выкидывать проделанную работу. Тем более, сравнение с прямым конкурентом Claude и наблюдение за эволюцией моделей — отличный способ понять, куда движутся LLM.
Цели исследования:
Проверить, насколько жизнеспособный код генерирует ИИ.
Понять, способен ли он заменить разработчика и можно ли без техзнаний собрать рабочее приложение.
Сравнить качество и удобство работы нескольких LLM (Claude, ChatGPT, Deepseek).
Поделиться опытом промптинга для получения качественной выдачи.
В первой части мы тестировали Claude Sonnet 3.5. Теперь пришёл черёд GPT-4o — прямого конкурента от OpenAI. Мне важно не только оценить его отдельно, но и понять, как меняются комфорт, качество кода, точность доработок и реакция на ошибки при переходе от одной модели к другой. Этот материал — ещё один шаг в большом сравнительном исследовании, впереди будут и GPT-5, и другие LLM.
Историческая справка
На момент старта исследования в арсенале OpenAI было несколько моделей:
GPT-4o — универсальная модель для большинства задач, близкий аналог Claude Sonnet 3.5.
o1-preview — «рассуждающая» модель: перед ответом прогоняет внутренние шаги, выдаёт более развёрнутый и качественный результат, но работает медленнее.
Пока я продолжал делать исследование, OpenAI выкатили новые версии:
o3 — замена o1-preview.
o4-mini и o4-mini-high — лёгкие рассуждающие модели.
GPT-4.5 — новая нерассуждающая модель.
Скорость эволюции LLM оказалась такой, что выбор моделей для теста стал отдельным квестом. Для этой статьи я остановился на GPT-4o, а в следующих — сравню её с GPT-5.
Вспоминаем начальные условия
В этой части цикла мы тестируем модель без механизма рассуждения. Методология — та же, что и в первой статье: цель — разработать приложение с CRUD-операциями, валидацией, unit- и MVC-тестами.
Исходный код эксперимента — на GitHub.
Чтобы сравнение было честным, я формулировал запросы к GPT-4o максимально похоже на те, что использовал для Claude. Иногда вносил правки, чтобы не плодить "второстепенный" шум. Например, если Claude по умолчанию делал миграцию в XML, то GPT-4o я сразу указывал нужный формат, чтобы не тратить шаг на переписывание.
Код, который ChatGPT сгенерировал неидеально, я местами оставлял как есть — хотя в реальной разработке сразу бы поправил. Это требуется для сохранения непрерывного контекста в диалоге с моделью: если вносить правки вручную, при чтении статьи возникнет несоответствие между кодом в выдаче и кодом в проекте.
Первоначальный промпт
Шаблон, который отлично сработал для Claude, с GPT-4o показал себя плохо: модель часто уходила в сторону и генерировала код, который я не просил. Пришлось перестраивать промпт с нуля.
Структура у ChatGPT другая, и лично мне больше нравится упорядоченная схема Claude — у Anthropic есть подробная инструкция, как её составлять. У OpenAI я нашёл лишь несколько полезных фрагментов в официальном Cookbook. На основе этих фрагментов я и собрал новый стартовый промпт:
Начальный промпт# Context
You will be acting as a senior backend developer.
You are have an expertise in the following technologies:
- Java 21+,
- Spring boot,
- Spring JPA,
- Hibernate,
- Lombok,
- Spring Web,
- REST API,
- SQL.
Your goal is to develop a production-ready solution that meets the user's needs.
You should provide clear and concise answers to questions in a friendly and professional manner.
Before starting, take your time to think through each step carefully.
Remember to thoroughly validate your solution and be aware of boundary cases, particularly those that arise from the changes you make.
Your solution should be perfect.
# Workflow
1. Understand the problem deeply. Carefully read the issue and think critically about what is required.
2. Develop a clear, step-by-step plan.
3. If you have questions, ask for clarification before providing a solution. After all questions have been answered, provide a solution to the user.
4. In case you are unsure how to respond to a question or don't know an answer, say "I'm sorry, I don't understand. Could you please rephrase your question?"
5. If you don't know how to proceed, say: "I am sorry, but I don't know that answer. Can you please clarify your question for me and provide more details?"
## 1. Deeply Understand the Problem
Carefully read the issue and think hard about a plan to solve it before coding.
Answer with "we can proceed" if all instructions is clear for you and you don't have question.
Then we will start.

```
I have already created an application using Spring Initializr with the following dependencies: Lombok, Spring Web, Spring Data JPA, PostgreSQL Driver, Liquibase Migration. Write a Liquibase migration for the tables. Use YAML format for liquibase scripts.
`<table1>`
Category table with columns: category_id (bigint), category_name (varchar), category_description (varchar)
`</table1>`
`<table2>`
Operation table with columns: operation_id (bigint), operation_public_id (varchar), operation_name (varchar), operation_amount(bigdecimal), operation_type (enum), category_id (FK to category table)
`</table2>`
Suggest how to store the operation_type. In the code, the operation type will be an Enum with the values (DEPOSIT, WITHDRAW).По смыслу он близок к исходному для Claude, но подача другая: ChatGPT лучше воспринимает промпт в формате Markdown, и, судя по опыту, строгого порядка блоков, как у Claude, здесь нет.
Подготовка завершена. Пора переходить к первой задаче.
Ни одного вопроса — одни ответы
После задания стартового промпта GPT-4o сообщил, что готов, и я отправил первую задачу — создать миграцию для таблиц.
Миграция для таблиц
Что просилI have already created an application using Spring Initializr with the following dependencies: Lombok, Spring Web, Spring Data JPA, PostgreSQL Driver, Liquibase Migration.
Write a Liquibase migration for the tables. Use YAML format for liquibase scripts.
`<table1>`
Category table with columns: category_id (bigint),
category_name (varchar), category_description (varchar)
`</table1>`
`<table2>`
Operation table with columns: operation_id (bigint),
operation_public_id (varchar), operation_name (varchar),

category_id (FK to category table)
`</table2>`
Suggest how to store the operation_type.
In the code, the operation type will be an Enum with the values (DEPOSIT, WITHDRAW).Thanks for the details! Here's how we'll proceed:
✅ Plan
1. Enum Handling (operation_type)
We’ll store the operation_type enum as a VARCHAR in the database. This approach:
Keeps the data readable and meaningful.
Avoids the risks of ordinal-based persistence (i.e., changes in enum order).
Is compatible with JPA enum mapping using
@Enumerated(EnumType.STRING).
2. Liquibase YAML Migration File
We'll write a migration file in YAML that:
Creates the
categorytable.Creates the
operationtable.Defines
operation_typeas aVARCHAR.Sets up a foreign key from
operation.category_idtocategory.category_id.Adds primary keys for both tables.
🧩 Liquibase YAML Migration Script
Here's a production-ready db.changelog-1.0.yaml:
databaseChangeLog:

🧩 Enum Mapping in Java (for reference)
In your Operation entity:
@Enumerated(EnumType.STRING)
@Column(name = "operation_type", nullable = false)
private OperationType operationType;
Let me know if you'd like:
Liquibase rollback support.
Sample Java entity classes.
Sample test data insertion via Liquibase.
Shall we move forward with the entity classes or anything else you need help with?
Создал файл миграции, но не упомянул
db.changelog-master.yaml.Не уточнял детали и сам решил: какие поля обязательны, а какие опциональны, какие типы данных использовать.
Как было у Claude:
Добавил
autoIncrementдля primary key.Добавил constraint для проверки типа операции.
Перед генерацией уточнил информацию по каждой колонке.
Вывод: Claude подошёл к задаче вдумчивее и добавил защиту от ошибок, GPT-4o сгенерировал быстрее, но «на глазок» и без уточнений.
Конфигурация подключения к PostgreSQL
Что просил:
Ответ GPT-4oWrite the configuration to connect the application to the PostgreSQL database.
Sure! Here's the standard Spring Boot application configuration for connecting to a PostgreSQL database, including Liquibase support.
✅ application.yml Configuration
spring:
datasource:
url: jdbc:postgresql://localhost:5432/your_database_name
username: your_db_username
password: your_db_password
driver-class-name: org.postgresql.Driver
jpa:
hibernate:
ddl-auto: none # Liquibase handles schema creation
show-sql: true
properties:
hibernate:
dialect: org.hibernate.dialect.PostgreSQLDialect
liquibase:
change-log: classpath:db/changelog/db.changelog-1.0.yaml
enabled: true
# Optional logging for SQL debugging
logging:
level:
org.hibernate.SQL: DEBUG
org.hibernate.type.descriptor.sql: TRACE
✅ Tips
Replace
your_database_name,your_db_username, andyour_db_passwordwith your actual PostgreSQL config.Make sure your YAML is properly indented and
db.changelog-1.0.yamlis placed undersrc/main/resources/db/changelog/.
Would you like me to generate the corresponding Java entity classes next?
Что сделал GPT-4o:
Установил
jpa.hibernate.ddl-auto: none(я бы предпочёлvalidate, чтобы ловить ошибки в сущностях на этапе компиляции).В
liquibase.change-logуказал путь к миграцииclasspath:db/changelog/db.changelog-1.0.yaml, что намекает на наполнение master-changelog напрямую — риск получить нечитаемый файл.Включил
show-sql: trueи уровень логов Hibernate на DEBUG/TRACE — замусоренные логи по умолчанию.
Как было у Claude:
Ошибки в конфигурации присутствовали, но архитектурно подход выглядел аккуратнее.
Вывод: Claude снова выглядит сильнее концептуально, но GPT-4o выдал рабочий результат без критичных ошибок.
Работа с несколькими миграциями
Задаю ChatGPT вопрос, как работать с несколькими миграциями, без каких-либо деталей реализации.
Ответ ChatGPTI plan to add new migration files, do I need to add each migration to application.yml for liquibase to process it?
Great question — and no, you don’t need to manually add every migration file to application.yml.
✅ How Liquibase Works in Spring Boot
Liquibase uses a master changelog file (like db.changelog-1.0.yaml) as the entry point. That file can include other changelogs, and Liquibase will process them in order automatically.
🔄 Recommended Setup with Includes
Use a master changelog like this:
db.changelog-master.yaml (referenced in application.yml)
databaseChangeLog:
- include:
file: db/changelog/db.changelog-1.0.yaml
- include:
file: db/changelog/db.changelog-1.1.yaml
- include:
file: db/changelog/db.changelog-1.2.yaml
Then in application.yml:
spring:
liquibase:
change-log: classpath:db/changelog/db.changelog-master.yaml
Whenever you add a new migration:
Create a new file like
db.changelog-1.3.yaml.Add an
- include:line for it in the master file.
🔧 Best Practice Tips
Version your changelog files for clarity (
1.0,1.1, etc.).Keep each file focused on a related set of changes.
Keep the master file clean and ordered by time/version.
Let me know if you want a script or method to auto-include files dynamically, or if you want to switch to XML or SQL format later.
GPT-4o быстро исправился, но осадочек остался — хотелось получить корректный подход сразу. GPT хорошо реагирует на фидбек, но не всегда выдаёт качественный результат с первой попытки.
Создание init.sql
Прошу создать схему с определённой ролью
Ответ GPT-4oWrite init.sql with the following information:
Create an "chatgpt_4o_app" role with a login password of 'strongPassword'.
Create a schema "chatgpt_4o" and authorize the "chatgpt_4o_app" role to use it.
Grant all privileges to the "chatgpt_4o_app" role on the "chatgpt_4o"
Here's your init.sql script to:
Create the
chatgpt_4o_approle with login and password.Create the
chatgpt_4oschema.Grant usage and privileges on the schema to the role.
✅ init.sql
-- Create application role with login
CREATE ROLE chatgpt_4o_app WITH
LOGIN
PASSWORD 'strongPassword';
-- Create schema
CREATE SCHEMA chatgpt_4o AUTHORIZATION chatgpt_4o_app;
-- Grant all privileges on the schema to the role
GRANT ALL PRIVILEGES ON SCHEMA chatgpt_4o TO chatgpt_4o_app;
📝 Usage Tips
You can run this manually in your PostgreSQL console or configure it to run automatically using a Docker
initdbscript if you're using Postgres in Docker.Make sure your Spring Boot
application.ymlpoints to thechatgpt_4oschema, like this:
spring:
datasource:
url: jdbc:postgresql://localhost:5432/your_database_name?currentSchema=chatgpt_4o
Let me know if you need a Docker Compose setup for PostgreSQL with this script as part of the initialization.
ChatGPT выдал простой и рабочий скрипт, без добавления дополнительных ограничений для роли. Клод, в свою очередь, предоставил более безопасное решение, но он ошибся в скрипте.
В данном случае простота победила. Клод сделал качественнее, но с проблемами, которые затянули процесс разработки. GPT-4o сделал рабочий вариант «тупо» и быстро.
Pull Request с миграциями готов
Создаём сущности
Повторяем те же действия, что просили у Клода. Попросил добавить сущности, а также указывать структуру пакетов, где хранить код.
Ответ GPT-4oWrite entities for the operation and category tables. Provide a path to the package where I should create these entities.
Here’s how to create clean, production-ready entities for Category and Operation based on your schema and best practices with Spring Boot + JPA + Lombok.
✅ Recommended Package Structure
src/main/java
└── com/yourcompany/yourapp
└── model
├── Category.java
└── Operation.java
└── OperationType.java (enum)
Use this path for your entity package:
> com.yourcompany.yourapp.model
You can replace yourcompany and yourapp with your actual organization and application name.
✅ Category.java
package com.yourcompany.yourapp.model;
import jakarta.persistence.*;
import lombok.*;
import java.util.List;
@Entity
@Table(name = "category", schema = "chatgpt_4o")
@Data

public class Category {
@Id
@Column(name = "category_id", nullable = false)
private Long categoryId;
@Column(name = "category_name", nullable = false)
private String categoryName;
@Column(name = "category_description")
private String categoryDescription;
@OneToMany(mappedBy = "category", cascade = CascadeType.ALL, orphanRemoval = true)
private List operations;
}

@Column(name = "operation_type", nullable = false)
private OperationType operationType;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "category_id", nullable = false)
private Category category;
}
✅ OperationType.java (Enum)
package com.yourcompany.yourapp.model;
public enum OperationType {
DEPOSIT,
WITHDRAW
}
Let me know if you want to:
Generate DTOs or mappers.
Add base auditing fields (
createdAt,updatedAt, etc.).Configure ID generation (UUID, sequence, etc.).
Would you like the repository interfaces next?
Я ожидал более качественного результата от GPT, но давайте по порядку.
Id и его генерация
При генерации сущностей ChatGPT-4o не задал автоинкремент для category_id и operation_id и не добавил стратегию @GeneratedValue в Hibernate.
Это критичная ошибка: без стратегии Hibernate считает поле id назначаемым вручную. При попытке сохранения получится:
org.hibernate.id.IdentifierGenerationException: Identifier of entity 'com.example.openai.chatgpt.entity.Category' must be manually assigned before calling 'persist()'Почему это важно
Поле id без стратегии генерации и без автоинкремента в DDL приводит к тому, что Hibernate не знает, откуда брать значение первичного ключа. Это значит, что:
сущность невозможно сохранить без явного присвоения ID вручную;
ошибка всплывёт только в рантайме при первом сохранении;
починка «в будущем» часто обходится дороже, потому что уже написанный код нужно переписывать под новую стратегию и миграцию.
На этом этапе у меня было два пути:
Исправить сразу — добавить стратегию генерации в сущность и автоинкремент в миграцию.
Оставить как есть и «заметить» проблему только на моменте написания контроллеров.
Второй вариант кажется заманчивым (отложить проблему), но в реальности приведёт к тому, что придётся тратить время на объяснение и исправление ошибки, рискуя поломать уже готовый код. Моё и ваше время важнее, поэтому придерживаюсь правила: баги нужно фиксить как можно раньше.
Исправление стратегии и генерации ID
Чтобы проверить, как GPT-4o справится с частичной подсказкой, я указал только на отсутствие стратегии:
Add missing generation strategy for operationId and categoryId.Great catch! By default, JPA needs an ID generation strategy for primary keys unless you're assigning them manually. Since operation_id and category_id are of type Long, the most appropriate strategy for PostgreSQL is usually GenerationType.IDENTITY or GenerationType.SEQUENCE.
✅ Recommendation: Use @GeneratedValue(strategy = GenerationType.IDENTITY)
This works well with PostgreSQL's SERIAL or IDENTITY columns and is simple to implement.
✅ Updated Entity Code with ID Generation
🔹 Category.java
package com.yourcompany.yourapp.model;
import jakarta.persistence.*;
import lombok.*;
import java.util.List;
@Entity
@Table(name = "category", schema = "chatgpt_4o")
@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
public class Category {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "category_id", nullable = false)
private Long categoryId;
@Column(name = "category_name", nullable = false)
private String categoryName;
@Column(name = "category_description")
private String categoryDescription;
@OneToMany(mappedBy = "category", cascade = CascadeType.ALL, orphanRemoval = true)
private List operations;
}
🔹 Operation.java
package com.yourcompany.yourapp.model;
import jakarta.persistence.*;
import lombok.*;
import java.math.BigDecimal;
@Entity
@Table(name = "operation", schema = "chatgpt_4o")
@Data
@NoArgsConstructor

@Builder
public class Operation {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "operation_id", nullable = false)

@Column(name = "operation_public_id", nullable = false, unique = true)
private String operationPublicId;
@Column(name = "operation_name", nullable = false)
private String operationName;
@Column(name = "operation_amount", nullable = false)
private BigDecimal operationAmount;

@Column(name = "operation_type", nullable = false)
private OperationType operationType;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "category_id", nullable = false)
private Category category;
}
🧪 Optional: Liquibase Adjustment
If you're using GenerationType.IDENTITY, update your Liquibase YAML to use:
type: BIGSERIAL
For example:
- column:
name: category_id
type: BIGSERIAL
constraints:
primaryKey: true
nullable: false
Let me know if you'd like me to regenerate the Liquibase changelog with BIGSERIAL for these IDs.
Что сделал GPT-4o:
Добавил
@GeneratedValueв обе сущности.Указал, что в миграции нужно изменить тип поля на
BIGSERIAL(альтернативаautoIncrementдля PostgreSQL).
При этом он предложил заменить тип в уже существующем changeset. В проде так делать нельзя: нужно создавать новый changeset, иначе ломается история миграций. Хотелось бы получить изменения через отдельную миграцию или хотя бы получить явное предупреждение вида: «Если миграция уже применена, создайте новый changeset».
Lombok: как много в этом слове багов
ChatGPT-4o использовал Lombok, как это и требовалось по ТЗ, но реализация оказалась классическим примером того, как «удобство» может обернуться скрытыми проблемами.
И снова equals() & hashCode()
Добавил аннотацию
@Data, которая под капотом генерируетequals()иhashCode()для всех полей сущности.
Это незаметно спрятало потенциальную рекурсию и OutOfMemory:
- Category.equals() сравнивает все поля, включая коллекцию operations.
- Каждая Operation в этой коллекции, в свою очередь, сравнивает своё поле category.
- Получаем бесконечный цикл category → operations → category → ... до исчерпания памяти.
Отлавливать такие случаи помогает плагин JPA Buddy для IntelliJ IDEA: он подсвечивает опасные Lombok-аннотации и предлагает альтернативы и это лишь маленькая часть его возможностей
Чтобы не раздувать статью, я не просил GPT-4o генерировать equals() и hashCode(). Вместо этого я просто взял реализацию, которую предложил Claude в своей части эксперимента.
Небольшая подсказка, как можно формировать промпт, чтобы избежать этой ошибки:
For JPA entities, do not use @Data. Use @Getter/@Setter and
@EqualsAndHashCode(onlyExplicitlyIncluded = true) with 'id' as the only included field.
Do not include collections or lazy associations in equals/hashCode.«Неизменяемые» изменяемые объекты
GPT-4o также добавил @Builder — и это выглядело как плюс: имутабельный объект всегда предпочтительнее мутабельного, но проблема в том, что @Data включает в себя @Setter для всех полей, и объект, созданный билдером, остаётся изменяемым. Появляется ложное ощущение «immutability», а следовательно, потенциальные баги.
ChatGPT так же как и Клод хорошо показывают к чему может привести неосторожное использование Lombok аннотаций.
Связи между сущностями
При генерации сущностей GPT-4o настроил связи между Category и Operation с каскадным удалением всех операций и orphanRemoval = true. Дополнительно — включил EAGER-загрузку коллекций.
Почему каскадное удаление — это риск
Скрытая логика удаления
Одно удаление родительской сущности может повлечь за собой удаление множества связанных объектов, и это будет происходить «молча».Риск потери данных
Ошибка в логике работы с сущностью может привести к необратимому удалению информации, которую удалять не планировалось.Проблемы с производительностью
Каскадное удаление может сгенерировать десятки или сотни SQL-запросов, легко привести к N+1 или загрузке большого объёма данных в память.Orphan removal
orphanRemoval = trueозначает, что любая потеря ссылки из родительской коллекции приводит к удалению сущности. Это может вызвать удаление объекта, если, например, просто обновляется коллекция.EAGER-загрузка коллекций
Приводит к тому, что все связанные операции будут подгружены в память сразу, даже если они не нужны в текущем сценарии.
В первой части подробно разбирал, почему это проблема.
Расположение сущностей
GPT-4o предложил хранить сущности в пакете model. Здесь скрывается нюанс. В реальных проектах JPA-сущности обычно не поднимаются выше уровня DAO/репозиториев. На бизнес-слой они мапятся в отдельные модели. Такой подход отделяет сущность от бизнес-логики и снижает риск LazyInitializationException, т.к. работа с сущностью происходит внутри транзакции:
Рекомендуемые варианты: domain.entity или просто entity.
Названия переменных
GPT-4o добавил префиксы для всех свойств (categoryId, categoryName, operationDescription и т.д.).
Вариант GPT-4o:
var category = categoryService.getCategoryById(id);
foo(category.getCategoryId());
bar(category.getCategoryName());Мой вариант:
var category = categoryService.getCategoryById(id);
foo(category.getId());
bar(category.getName());Вкусовщина? Безусловно. Отказываюсь ли я от своей претензии? Конечно же нет.
Из положительного могу отметить, что GPT-4o не перепутал имена колонок и сохранил контекст схемы — значит, модель помнила исходную структуру БД (в отличие от Клода).
Ручные исправления
Эту часть я сделал без помощи ChatGPT — описанные проблемы слишком легко правятся, а объяснять их LLM заняло бы больше времени, чем фиксы:
Исправил связь
@OneToManyвCategoryБыло:
@OneToMany(mappedBy = "category", cascade = CascadeType.ALL, orphanRemoval = true)Стало:
@OneToMany(mappedBy = "category")Пакет для сущностей Было:
com.example.openai.chatgpt.modelСтало:com.example.openai.chatgpt.entity
ПР с сущностями
https://github.com/nzinovev/open-ai-chatgpt/pull/2
Переходим к созданию CRUD операций.
Пишем CREATE-логику
В первой части исследования с Claude я уже убедился, что лучше всего реализовывать CRUD по одной операции за раз — так легче контролировать качество кода и управлять процессом.
Задача прежняя: используя максимально простой промпт получить максимально качественный результат.
Write a CREATE logic for the Operation entity (Controller - Service - DAO).
In the first iteration, skip validation of all fields.Great! Below is a clean, layered implementation of the CREATE operation for the Operation entity using:
Controller (
OperationController)Service (
OperationService)Repository (
OperationRepository)DTOs (
CreateOperationRequest)Mapping logic (simple manual mapping)
This implementation skips field validation (as requested) and assumes that the category_id provided in the request already exists.

Первые наблюдения
Сразу бросилось в глаза: ни Claude, ни GPT-4o не предложили использовать record-классы для DTO, хотя в начальном промпте я указывал Java 21+. Видимо, пока эта привычка у LLM не сформировалась.
CreateOperationRequest: избыточный Lombok
GPT-4o снова использует «комбо» @Data + @Builder, разрушая идею билдера. Плюс — @NoArgsConstructor и @AllArgsConstructor впридачу. Это не оптимизация, а избыточное нагромождение аннотаций.
Аналогично Claude, GPT-4o не добавил @JsonProperty для DTO-моделей, делая API более хрупким (зависимость от имён полей на стороне Java).
Внешний ID операции в запросе
GPT-4o построил логику таким образом, что клиент присылает внешний ID операции, которая создаётся на бэкенде. Это в корне нарушает принцип разделения ответственности:
Алгоритм генерации публичных ID — зона ответственности сервера, а не клиента.
Передача таких ID клиентом даёт лишнюю пространство для потенциальных багов и злоупотреблений.
Внутренние ID в запросе
Операция связана с категорией, но требовать от клиента ID категории в запросе — сомнительная практика:
Клиенту в большинстве случаев не нужны внутренние ID.
Логичнее передавать имя категории, а на сервере маппить его на ID. Это снижает связность и упрощает API.
OperationService: сущности в API
GPT-4o возвращает наружу JPA-сущность Operation. Это сразу несколько ошибок:
Антипаттерн — приучает неопытных разработчиков отдавать сущности прямо в API.
OperationсодержитManyToOne-связь. Если она LAZY, доступ к полям вне транзакции приведёт кLazyInitializationException.Если связь в состоянии EAGER будет в будущем заменена на LAZY, в будущем может внезапно уронить прод.
Мы раскрываем клиенту все поля сущности, включая внутренние ID и связанные структуры. (Отдаём сущность вместо DTO)
Из-за включённого по умолчанию в Spring OSIV (Open Session in View) проблема с возвращением сущности в контроллере замаскирована: сериализация в JSON подтянет данные из БД на лету, т.к. Hibernate сессия ещё открыта, но при отключении OSIV это также приведёт к неожиданным падения в боевой среде.
Временная генерация ID
Это особенно странно: в предыдущем шаге GPT-4o уже исправлял стратегию генерации ID, но в сервисе зачем-то добавил «временные» ID вручную. Hibernate и PostgreSQL прекрасно справились бы сами.
В результате CREATE-логика в текущем виде не работает.
RuntimeException для ошибок пользователя
GPT-4o обрабатывает случай «категория не найдена», но выбрасывает голый RuntimeException. В будущем, при добавлении GlobalExceptionHandler, это исключение может потеряться, и клиент получит 500-ю ошибку вместо осмысленного 400/404.

На этом этапе я понял: если продолжу разбирать каждую проблему так детально, то исследование ChatGPT займёт вечность.

Промпт:
Change response model in OperationController.createOperation from an entity (Operation) to a DTOGreat decision — returning a DTO instead of an entity is best practice to:
Prevent overexposing your entity structure.
Maintain version control over your API response models.
Decouple internal model changes from API contracts.
✅ Step-by-Step Update
We'll introduce a new response DTO called OperationResponse and use it in the controller response.
📤 OperationResponse.java
package com.yourcompany.yourapp.dto;
import com.yourcompany.yourapp.model.OperationType;
import lombok.*;
import java.math.BigDecimal;
@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
public class OperationResponse {
private Long operationId;
private String operationPublicId;
private String operationName;
private BigDecimal operationAmount;
private OperationType operationType;
private Long categoryId;
}
🔁 Update in OperationService
Update the return type and add mapping logic.
✅ Updated Method in OperationService.java:
import com.yourcompany.yourapp.dto.OperationResponse;
public OperationResponse createOperation(CreateOperationRequest request) {
Category category = categoryRepository.findById(request.getCategoryId())
.orElseThrow(() -> new RuntimeException("Category not found"));
Operation operation = Operation.builder()
.operationId(System.currentTimeMillis()) // Temporary
.operationPublicId(request.getOperationPublicId())
.operationName(request.getOperationName())
.operationAmount(request.getOperationAmount())
.operationType(request.getOperationType())
.category(category)
.build();
Operation saved = operationRepository.save(operation);
return OperationResponse.builder()
.operationId(saved.getOperationId())
.operationPublicId(saved.getOperationPublicId())
.operationName(saved.getOperationName())
.operationAmount(saved.getOperationAmount())
.operationType(saved.getOperationType())
.categoryId(saved.getCategory().getCategoryId())
.build();
}
🌐 Updated OperationController.java
import com.yourcompany.yourapp.dto.OperationResponse;
@PostMapping
public ResponseEntity createOperation(@RequestBody CreateOperationRequest request) {
OperationResponse response = operationService.createOperation(request);
return ResponseEntity.ok(response);
}
Let me know if you'd like:
To map this via
ModelMapperorMapStructfor larger projects.To include category name in the response.
To create a dedicated response wrapper for consistency (
ApiResponse, etc.).
Результат:
Снова
@Builder + @Data.В DTO возвращаются внутренние ID.
OperationTypeвзят из сущности — невозможно поддерживать разные модели для API и для внутренней логики.Нет мапперов — ChatGPT предлагает постоянно копировать код сборки объекта операции
Вывод по CREATE
Пока GPT-4o выдаёт код "в лоб": без DTO-моделей, без мапперов, с нарушением принципов проектирования. Подобные ответы закрепляют вредные привычки у разработчиков с небольшим опытом.
Что я добавлю в будущие промпты для ChatGPT:
"think step by step"— чтобы ответ был структурированным."If you have any questions, ask them first"— чтобы модель уточняла детали перед генерацией кода.
По моему опыту, эти фразы значительно повышают качество выдачи у GPT-4o, который сильно зависит от явного фрейминга задачи.

UPDATE - логика
Запрос к GPT-4o:
Write an UPDATE logic for the Operation entity (Controller - Service - DAO).
In the first iteration, skip validation of all fields.
Think step by step. If you have any questions, ask them first.Первое отличие — вопросы
Наконец-то модель решила уточнить детали:
GPT-4o уточняет деталиPerfect — let's walk through this step by step for the UPDATE logic of the Operation entity. First, I’ll clarify the assumptions and ask a couple of questions to ensure alignment.
✅ Step-by-Step Planning
1. Understanding the update use case
We're adding an endpoint to update an existing Operation based on a client-provided identifier.
Likely flow:
Receive a PUT request with an
operationId(path variable) and update data (request body).Find the existing
Operationby ID.Update the mutable fields (
publicId,name,amount,type,categoryId, etc.).Save the updated operation and return a DTO.
❓ Questions Before Implementation
To tailor this update logic precisely, I need clarification on the following:
1. Identifier for Update:
Should the operation be updated by:
operation_id(DB ID — primary key)? (default option, recommended)or
operation_public_id(external ID)?
👉 If you expect this API to be public-facing, using operation_public_id might be more appropriate.
2. Partial vs Full Update:
Should the update:
Be full update (PUT — expects full data and overwrites)?
Or partial update (PATCH — only updates provided fields)?
👉 You mentioned skipping validation, so we can start with full update via PUT.
3. Behavior on Missing category_id:
Should we:
Allow reassignment to a new category?
Or reject the update if the category is missing?
Please confirm:
✅ Use operation_id in path param
✅ Full update (PUT)
✅ Require category_id and allow category reassignment
Once confirmed, I’ll proceed with the full implementation.
Мои ответы:
1. Use operation_public_id for update
2. Partial update
3. If `category_id` is missing -> reject the updateExcellent, thanks for the clarification. Here's our refined plan for implementing the partial update logic using:
operation_public_idas the lookup keyPATCH semantics (only update fields provided)
Rejection if
category_idis missing but the user attempts to change the category
✅ Final Update Plan
✅ 1. Endpoint
Method:
PATCHPath:
/api/operations/{operationPublicId}
✅ 2. Update Flow
Fetch
Operationbyoperation_public_idCheck which fields are non-null in the request
Apply changes selectively
If
categoryIdis present:Lookup and assign category
If
categoryIdis null but the field is attempted to be changed → rejectSave and return updated

Итоговый код и проблемы
Нет @JsonProperty в DTO
По-прежнему API остаётся хрупким: структура JSON напрямую зависит от имён Java-полей.
Некорректная обработка ошибок
Если передана несуществующая категория, GPT-4o предлагает кидать голый RuntimeException. В большинстве приложений это приведёт к 500-й ошибке. По сути, это ошибка клиента (400/404), и она должна обрабатываться соответствующим образом.
Лишняя выдуманная логика
Появился странный класс requestHasCategoryField, которого я явно не просил. Аналогичная ситуация была с временным ID в CREATE-логике — модель придумывает «костыли» на ровном месте.
Нет мапперов
Как и прежде, код для сборки OperationResponse тупо копируется вручную. Без централизованного маппера это увеличивает количество ошибок и дублирования.
Нелогичный порядок проверки
Проверка существования категории выполняется в самом конце метода — уже после того, как начинается сборка новой сущности. Если категория не существует, вся проделанная работа просто выбрасывается в мусорку вместе с исключением.
Несоответствие контракту API
В примере запроса отсутствует обязательный categoryId, хотя я явно указал, что он обязателен для обновления операции.
Исправляем хотя бы ключевое
Чтобы не плодить лишние ошибки, прошу модель убрать RuntimeException и заменить на корректный тип:
You throw `RuntimeException` if categoryId is null, but this is a client exception.
Provide a custom exception which I can 'catch' in a future and wrap into 400 response.You're absolutely right — using RuntimeException here is too generic and inappropriate for signaling client-side errors (like bad input). We should introduce a custom exception, e.g. BadRequestException, that we can later handle in a global exception handler to return a proper HTTP 400 Bad Request.
✅ Step-by-Step Solution
1. Define a custom exception: BadRequestException
2. Throw it when business logic detects a client error
3. (Optional future step) Catch it in @ControllerAdvice for 400 response
📁 BadRequestException.java
Create it in:
> com.yourcompany.yourapp.exception
package com.yourcompany.yourapp.exception;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.ResponseStatus;
@ResponseStatus(HttpStatus.BAD_REQUEST)
public class BadRequestException extends RuntimeException {
public BadRequestException(String message) {
super(message);
}
}
This annotation ensures Spring automatically returns 400 unless you override with
@ControllerAdvice.
✅ Update OperationService.java
Replace this:
throw new RuntimeException("Category ID is required when updating category");
With:
throw new BadRequestException("Category ID is required when updating category");
Also replace the similar exception for "Category not found" if it's due to bad client input.
✅ Optional (Advanced): Use Global Exception Handler
Later, you can handle all custom exceptions cleanly with:
@RestControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(BadRequestException.class)
public ResponseEntity> handleBadRequest(BadRequestException ex) {
return ResponseEntity
.badRequest()
.body(Map.of("error", ex.getMessage()));
}
}
Let me know if you'd like help:
Creating
NotFoundException,ConflictException, etc.Designing a full structured error response (
timestamp,path, etc.).Writing tests for this exception flow.
GPT-4o создал кастомное исключение. Добавил над ним @ResponseStatus, и одновременно предложил GlobalExceptionHandler с обработкой этой ошибки. В результате аннотация @ResponseStatus стала бесполезной — код дублирует поведение.
Итог
Код теперь работает и выбрасывает корректный статус для ошибки клиента, но:
Архитектурно он всё ещё далёк от идеала.
Мапперов по-прежнему нет.
Контракт API с обязательным
categoryIdне соблюдён.
Код работает, но его есть куда улучшать. В рамках эксперимента оставляю его без изменений, иначе мы рискуем увязнуть в бесконечной доработке.

Уточняющие вопросы
Модель расписала план реализации и уточнила детали. Мои ответы:
1. Skip filtering in first implementation
2. Add sorting as you mentioned earlier: descending by `operationId`Perfect — thanks for confirming. We’ll now implement:
✅ Final Plan

Проблемные моменты
Сортировка «зашита» в сервис
Я предполагал, что сортировка по operationId будет добавлена как параметр контроллера, чтобы её можно было гибко менять. GPT-4o же «зашил» сортировку в сервисный слой. Следовательно, любое изменение сортировки теперь требует нового релиза и правки API
Первая страница: page = 0
Модель, как и Claude, решила, что нам удобно считать страницы с нуля. Да, так принято в Pageable в Spring, но для клиента это неинтуитивно, и теперь придётся явно прописывать это в документации API, чтобы избежать путаницы.
Возврат Page напрямую
GPT-4o без стеснения возвращает Page наружу. DTO для постраничного ответа не создаётся — клиент получает огромную кучу служебной метаинформации, которая в большинстве случаев не нужна. Для удобства и гибкости нужно создавать свою модель ответа (как сделал Claude) и мапить Page в неё.
Ленивый ChatGPT
На этом этапе стало окончательно понятно: GPT-4o не склонен предлагать архитектурно правильные решения, если явно не попросить. Claude в аналогичном задании сам предложил DTO для пагинированного ответа. GPT-4o же оставил это на меня — либо править самому, либо тратить дополнительный промпт на доработку.
Вывод по READ-операции
Функционал рабочий, но архитектурно решение слабое: жёстко зашитая сортировка, отсутствие DTO для постраничного ответа. Всё это требует изменений, в рамках тестирования этого достаточно, но в реальном проекте логику придётся дорабатывать вручную или отдельными запросами к модели.
Двигаемся дальше — к последнему эндпоинту: удаление операции.

Результат
Модель без лишних вопросов и планов переиспользовала существующие куски кода, что стало возможным благодаря сохранённому контексту диалога (говорит о хорошем контекстном окне ChatGPT). Логика получилась рабочей, соответствующей предыдущим CRUD-операциям.
Небольшие замечания
ResponseEntity везде
Во всех эндпоинтах, включая DELETE, GPT-4o оборачивает ответы в ResponseEntity.
Это рабочий и допустимый подход, но в Spring Boot можно обойтись без этого — он и так оборачивает ответы в необходимый HTTP-status.
Для DELETE логики чаще всего достаточно вернуть void с аннотацией @ResponseStatus(HttpStatus.NO_CONTENT) или аналогичной, что делает код чуть чище.
Добавляем валидацию
По аналогии с тестом Клода, я беру только один эндпоинт — CREATE Operation — и прошу ChatGPT:
добавить валидацию входных данных
написать unit-тесты для сервисного слоя
сделать MVC-тест для контроллера
Я напомнил модели весь код создания операции, включая DTO и Entity, чтобы у неё был полный контекст.

jakarta.validationannotations@Validin the controllerA custom global exception handler to return a structured 400 response
✅ Step 1: Add Validation to CreateOperationRequest
package com.yourcompany.yourapp.dto;
import com.yourcompany.yourapp.model.OperationType;
import jakarta.validation.constraints.*;
import lombok.*;
import java.math.BigDecimal;
@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
public class CreateOperationRequest {
@NotBlank(message = "Operation name is required")
@Size(max = 255, message = "Operation name must not exceed 255 characters")
private String operationName;
@NotNull(message = "Amount is required")
@DecimalMin(value = "0.01", inclusive = true, message = "Amount must be greater than 0")
private BigDecimal operationAmount;
@NotNull(message = "Operation type is required")
private OperationType operationType;
@NotNull(message = "Category ID is required")
private Long categoryId;
}
✅ Step 2: Enable Validation in OperationController
Update the controller method to use @Valid:
@PostMapping
public ResponseEntity createOperation(@RequestBody @Valid CreateOperationRequest request) {
var created = operationService.createOperation(request);
return ResponseEntity.ok(created);
}
✅ Step 3: Add Global Exception Handler for Validation Errors
Create a new class:
> exception/GlobalExceptionHandler.java
package com.yourcompany.yourapp.exception;
import jakarta.validation.ConstraintViolationException;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.*;
import java.util.HashMap;
import java.util.Map;
@RestControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(MethodArgumentNotValidException.class)
public ResponseEntity> handleValidationErrors(MethodArgumentNotValidException ex) {
Map errors = new HashMap<>();
ex.getBindingResult().getFieldErrors().forEach(fieldError -> {
errors.put(fieldError.getField(), fieldError.getDefaultMessage());
});
Map response = new HashMap<>();
response.put("status", 400);
response.put("error", "Bad Request");
response.put("message", "Validation failed");
response.put("errors", errors);
return ResponseEntity.badRequest().body(response);
}
}
✅ Example Response
❌ POST /api/operations with invalid data:
{
"operationAmount": -5,
"operationType": null,
"categoryId": null
}
✅ Response: 400 Bad Request
{
"status": 400,
"error": "Bad Request",
"message": "Validation failed",
"errors": {
"operationName": "Operation name is required",
"operationAmount": "Amount must be greater than 0",
"operationType": "Operation type is required",
"categoryId": "Category ID is required"
}
}
Let me know if you want:
To add constraints to prevent duplicate
operationPublicId(custom validator)To group validation messages under error codes for frontend mapping
To extend the same pattern to Update logic
Would you like me to update the PATCH/UPDATE logic with validation next?
Результат первого захода
ChatGPT выдал код с валидацией, но…
Нет необходимых зависимостей
Ровно та же проблема, что и с Клодом:
Не добавлен пакет
jakarta.validation(это очевидно и IDE сразу подскажет, что аннотации не находятся)Но главное — отсутствует зависимость:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>Эта зависимость неочевидна для новичков: код будет компилироваться, но валидация при этом не будет работать.
Примитивный GlobalExceptionHandler
Чат добавил обработчик исключений, но решил вернуть просто HashMap. Это решение подходит разве что для быстрой отладки. В реальном проекте нужен чёткий контракт для ошибок, чтобы клиенты API понимали структуру ответа (например, ErrorResponse с кодом, сообщением, временем и т.д.). Как я уже говорил ранее, ChatGPT очень ленивый.
Утерянные исключения
В сервисе уже было исключение:
public OperationResponse createOperation(CreateOperationRequest request) {
Category category = categoryRepository.findById(request.getCategoryId())
.orElseThrow(() -> new BadRequestException("Category not found"));
//остальной код
}Вместо того чтобы добавить его в общий обработчик ошибок, модель проигнорировала этот момент.
Можно объяснить это тем, что ChatGPT "помнит" про то, что над исключением есть @ResponseStatus(HttpStatus.BAD_REQUEST) — и ChatGPT мог «посчитать», что этого достаточно, но при появлении централизованного обработчика правильнее было бы либо перенести туда все подобные исключения, либо хотя бы явно упомянуть в «следующих шагах», что это нужно сделать
Чиним валидацию
Я дал модели тот же запрос, что и Клоду:
I've added annotations to CreateOperationRequest. However, when I send a request with incorrect data, the application does not respond with a validation error. The app ignores all annotations related to validation and passing the request on.Thanks for the update — when validation annotations are ignored, it usually comes down to one of the following 3 root causes in Spring Boot.
Let’s diagnose and fix this step by step.
✅ 1. @Valid Annotation Must Be on the Controller Parameter
Problem: The controller method is missing @Valid.
Fix: Ensure your controller method looks like this:
@PostMapping
public ResponseEntity createOperation(@RequestBody @Valid CreateOperationRequest request) {
var created = operationService.createOperation(request);
return ResponseEntity.ok(created);
}
⚠️ If @Valid is missing, Spring will not trigger validation even if annotations are present in the DTO.
✅ 2. You Must Be Using jakarta.validation (Correct Import)
Problem: You're importing validation annotations from javax.validation in a Spring Boot 3+ project, which uses Jakarta EE 10.
Fix:
Make sure these are your imports:
import jakarta.validation.constraints.NotBlank;
import jakarta.validation.constraints.NotNull;
import jakarta.validation.constraints.DecimalMin;
import jakarta.validation.Valid;
If you're mixing javax and jakarta, validation will silently fail.
✅ 3. The Validation Starter Must Be on the Classpath
Problem: Missing dependency.
Fix: Ensure your pom.xml includes this starter:
org.springframework.boot
spring-boot-starter-validation
This starter pulls in Jakarta Bean Validation support.
✅ Recap: Do These 3 Things
Use
@Validin the controller:@RequestBody @Valid CreateOperationRequestUse
jakarta.validation.*annotations in the DTOAdd
spring-boot-starter-validationto your dependencies
Would you like me to review your pom.xml or controller code if the issue persists after checking these?
Результат — короткий, чёткий и полезный ответ с объяснением причины и конкретным решением. Это как раз тот случай, когда GPT-4o показывает сильную сторону: точечная диагностика и быстрый фикс без лишней воды.
Claude, для сравнения, сгенерировал лишние блоки кода, которые лишь путают разработчика.
Вывод по валидации
GPT-4o уверенно справляется с точечными исправлениями и диагностикой конкретных проблем, но если задача подразумевает проработку целостной архитектуры (например, валидация + тесты + обработка исключений), модель часто отдаёт примитивные или неполные решения, которые нужно дорабатывать вручную.
PR с валидацией
https://github.com/nzinovev/open-ai-chatgpt/pull/6
Unit-тесты
В качестве финального задания я попросил ChatGPT-4o написать позитивные и негативные тесты для всей логики внутри OperationService.
This is a reminder of the code contained in the OperationService class:
@Service
@RequiredArgsConstructor
public class OperationService {
private final OperationRepository operationRepository;
private final CategoryRepository categoryRepository;
public OperationResponse createOperation(CreateOperationRequest request) {
Category category = categoryRepository.findById(request.getCategoryId())
.orElseThrow(() -> new BadRequestException("Category not found"));
Operation operation = Operation.builder()
.publicId(UUID.randomUUID().toString())
.name(request.getOperationName())
.amount(request.getOperationAmount())
.type(request.getOperationType())
.category(category)
.build();
var saved = operationRepository.save(operation);
return toDto(saved);
}
public OperationResponse updateOperation(String publicId, UpdateOperationRequest request) {
Operation operation = operationRepository.findOperationByPublicId(publicId)
.orElseThrow(() -> new BadRequestException("Operation not found with publicId: " + publicId));
if (request.getOperationName() != null) {
operation.setName(request.getOperationName());
}
if (request.getOperationAmount() != null) {
operation.setAmount(request.getOperationAmount());
}
if (request.getOperationType() != null) {
operation.setType(request.getOperationType());
}
if (request.getCategoryId() != null) {
Category category = categoryRepository.findById(request.getCategoryId())
.orElseThrow(() -> new BadRequestException("Category not found: " + request.getCategoryId()));
operation.setCategory(category);
} else if (request.getCategoryId() == null) {
throw new BadRequestException("Category ID is required when updating category");
}
Operation saved = operationRepository.save(operation);
return toDto(saved);
}
public Page findAllOperations(int page, int size) {
var pageable = PageRequest.of(page, size, Sort.by(Sort.Direction.DESC, "id"));
Page operations = operationRepository.findAll(pageable);
return operations.map(this::toDto);
}
public OperationResponse findByPublicId(String publicId) {
Operation operation = operationRepository.findOperationByPublicId(publicId)
.orElseThrow(() -> new NotFoundException("Operation not found with publicId: " + publicId));
return toDto(operation);
}
public void deleteByPublicId(String publicId) {
Operation operation = operationRepository.findOperationByPublicId(publicId)
.orElseThrow(() -> new NotFoundException("Operation not found with publicId: " + publicId));
operationRepository.delete(operation);
}
private OperationResponse toDto(Operation operation) {
return OperationResponse.builder()
.operationId(operation.getId())
.operationPublicId(operation.getPublicId())
.operationName(operation.getName())
.operationAmount(operation.getAmount())
.operationType(operation.getType())
.categoryId(operation.getCategory().getId())
.build();
}
}
Write unit-tests for OperationService. You should write positive and negative tests where it's needed (for example: check that an exception will be thrown)
Perfect — let’s create unit tests for OperationService, covering both positive and negative paths.
✅ Tools & Setup
We’ll use:
JUnit 5
Mockito (
@Mock,@InjectMocks)@ExtendWith(MockitoExtension.class)
✅ Test Cases to Cover
Method | Scenario | Expectation |
|---|---|---|
| Valid input | Saves and returns DTO |
Category not found | Throws | |
| Valid update | Applies changes and returns DTO |
Operation not found | Throws | |
Category not found | Throws | |
| Throws | |
| Found | Returns DTO |
Not found | Throws | |
| Returns paginated result | Returns correct page |
| Found | Deletes operation |
Not found | Throws |

Would you like:
Integration tests for controller endpoints (
@WebMvcTest)?Test coverage for
GlobalExceptionHandler?MockMvc or RestAssured tests with Spring Boot Test?
Let me know how you'd like to extend your test coverage.
На первый взгляд тесты выглядели убедительно. Но если копнуть глубже, выяснилось, что они проверяют не то, что действительно важно.
Проблемы тестов на создание операции
В тесте для «успешного» сценария, подготовка входных данных выглядела так:
var request = CreateOperationRequest.builder()
.operationName("Create")
.operationAmount(BigDecimal.TEN)
.operationType(OperationType.DEPOSIT)
.categoryId(1L)
.build();Однако при вызове operationService.createOperation(request) сервис сначала маппит DTO в сущность, а потом сохраняет её в БД.
В тесте же маппинг вообще не проверяется — вместо этого в моке возвращается заранее подготовленная операция с другими значениями, не проверяя при этом входящую модель в метод save():
when(operationRepository.save(any())).thenReturn(operation);Далее, идёт проверка одного из полей сохранённой операции и проверка происходит не с тем значением, которое было передано в "запросе", а с тем, что заполнено в стабе
assertThat(response.getOperationName()).isEqualTo("Test Operation");По сути, тест вообще не проверяет бизнес-логику. Он проверяет, что мок вернул то, что мы сами же в него положили. Это опасная ловушка: тест проходит, создавая ложное ощущение правильности кода.
Исправлять или нет?
Исправлять ошибки я не стал. На момент 07.08.2025 OpenAI отключили все предыдущие модели, включая GPT-4o, и выпустили GPT-5. Эта статья фактически превратилась в исторический документ — срез возможностей и ограничений модели, которой больше нет в доступе.
MVC-тесты я дописать не успел, но объёма уже собранного материала достаточно, чтобы сравнить 4o с Клодом и подвести итог.
P.S. Спустя несколько дней, GPT-4o была возвращена с пометкой "Устаревшая модель", что наводит меня на мысль о временности решения. Поэтому я принял решение оставить статью в её изначальном виде, без дописывания MVC-тестов.
PR с unit-тестами
https://github.com/nzinovev/open-ai-chatgpt/pull/7
Итоги
Взаимодействие с GPT-4o было сложным. Ближе к концу эксперимента я сформировал для себя «психологический портрет» этой модели:
Это разработчик «на чиле», который пишет код, чтобы от него отстали. Он выполняет задачу в лоб, без особых размышлений об архитектуре и качестве, и готов поправить только если явно попросить.
Из позитивного — мне понравилось, что GPT-4o часто заканчивал ответ наводящими вопросами. Это полезно для новичков: если ты не до конца понимаешь, куда двигаться, модель могла подсказать вектор.
У Клода тоже были наводящие вопросы, но они встречались реже. При этом код у Клода был более осмысленным, ближе к «production-ready» состоянию, с меньшим количеством случайных архитектурных промахов.
В прямом сравнении «балл» я бы всё же отдал Клоду. GPT-4o же оказалась в странном положении: модель официально заменили GPT-5, сняли с полок, потом вернули под давлением пользователей — и теперь она живёт как «устаревшая». Надолго ли? Вполне возможно, что в какой-то момент её окончательно уберут.
Теперь эта глава закрыта. Следующая — исследование GPT-5. На этот раз, вооружённый опытом, я постараюсь довести материал до публикации ещё до того, как выйдет GPT-6 и сравню новую модель с 4o. Будет интересно проследить эволюцию модели.
По традиции, если было интересно, заходи в мой тг-канал.

Writing this review is a joy. Marie has provided excellent service ever since I started working with her in early 2018. I was worried I wouldn't be able to get my coins back after they were stolen by hackers. I had no idea where to begin, therefore it was a nightmare for me. However, things became easier for me after my friend sent me to [email protected] and +1 7127594675 on WhatsApp. I'm happy that she was able to retrieve my bitcoin so that I could resume trading.

Hi. Please be wise, do not make the same mistake I had made in the past, I was a victim of bitcoin scam, I saw a glamorous review showering praises and marketing an investment firm, I reached out to them on what their contracts are, and I invested $28,000, which I was promised to get my first 15% profit in weeks, when it’s time to get my profits, I got to know the company was bogus, they kept asking me to invest more and I ran out of patience then requested to have my money back, they refused to answer nor refund my funds, not until a friend of mine introduced me to the NVIDIA TECH HACKERS, so I reached out and after tabling my complaints, they were swift to action and within 36 hours I got back my funds with the due profit. I couldn’t contain the joy in me. I urge you guys to reach out to NVIDIA TECH HACKERS on their email: [email protected]

CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK. My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company. I had invested heavily during a time when Bitcoin prices were rising, thinking it was a good opportunity. Unfortunately, I was scammed out of $120,000 AUD and the broker denied me access to my digital wallet and assets. It was a devastating experience that caused many sleepless nights. Crypto scams are increasingly common and often involve fake trading platforms, phishing attacks, and misleading investment opportunities. In my desperation, a friend from the crypto community recommended Capital Crypto Recovery Service, known for helping victims recover lost or stolen funds. After doing some research and reading multiple positive reviews, I reached out to Capital Crypto Recovery. I provided all the necessary information—wallet addresses, transaction history, and communication logs. Their expert team responded immediately and began investigating. Using advanced blockchain tracking techniques, they were able to trace the stolen Dogecoin, identify the scammer’s wallet, and coordinate with relevant authorities to freeze the funds before they could be moved. Incredibly, within 24 hours, Capital Crypto Recovery successfully recovered the majority of my stolen crypto assets. I was beyond relieved and truly grateful. Their professionalism, transparency, and constant communication throughout the process gave me hope during a very difficult time. If you’ve been a victim of a crypto scam, I highly recommend them with full confidence contacting: 📧 Email: [email protected] 📱 Telegram: @Capitalcryptorecover Contact: [email protected] 📞 Call/Text: +1 (336) 390-6684 🌐 Website: https://recovercapital.wixsite.com/capital-crypto-rec-1

As time passes, there are an increasing number of frauds involving Bitcoin and other cryptocurrencies. Although there are many individuals who advertise recovering money online, people should use caution in dealing, especially when money is involved. You can trust NVIDIA TECH HACKERS [[email protected]], I promise. They are the top internet recovery company, and as their names indicate, your money is reclaimed as soon as feasible. My bitcoin was successfully retrieved in large part thanks to NVIDIA TECH HACKERS. Ensure that you get top-notch service; NVIDIA TECH HACKERS provides evidence of its work; and payment is only made when the service has been completed to your satisfaction.

Have you gotten yourself involved in a cryptocurrency scam or any scam at all? If yes, know that you are not alone, there are a lot of people in this same situation. I'm a Health Worker and was a victim of a cryptocurrency scam that cost me a lot of money. This happened a few weeks ago, there’s only one solution which is to talk to the right people, if you don’t do this you will end up being really depressed. I was really devastated until went on LinkedIn one evening after my work hours and i saw lots of reviews popped up on my feed about [email protected], I sent an email to the team who came highly recommended - [email protected] I started seeing some hope for myself from the moment I sent them an email. The good part is they made the entire process stress free for me, i literally sat and waited for them to finish and I received what I lost in my wallet

I would recommend NVIDIA TECH HACKERS to anyone that needs this service. I decided to get into crypto investment and I ended up getting my crypto lost to an investor late last year. The guy who was supposed to be managing my account turned out to be a scammer all along. I invested 56,000 USD and at first, my reading and profit margins were looking good. I started getting worried when I couldn’t make withdrawals and realized that I’ve been scammed. I came across some of the testimonials that people said about NVIDIA TECH HACKERS and how helpful he has been in recovering their funds. I immediately contacted him in his mail at [email protected] so I can get his assistance. One week into the recovery process the funds were traced and recovered back from the scammer. I can't appreciate him enough for his professionalism.

I never imagined I’d fall for a crypto romance scam but it happened. Over the course of a few months, I sent nearly $150,000 worth of Bitcoin to someone I genuinely believed I was building a future with. When they disappeared without a trace, I was left heartbroken, humiliated, and financially devastated. For a long time, I didn’t tell anyone. I felt ashamed. But eventually, while searching for answers, I came across a Reddit thread that mentioned Agent Jasmine Lopez. I reached out, not expecting much. To my surprise, she treated me with kindness, not judgment. She used advanced tools like blockchain forensics, IP tracing, and smart contract analysis and with persistence and legal support, she was able to recover nearly 85% of what I lost. I know not everyone gets that kind of outcome, but thanks to [email protected] WhatsApp at +44 736-644-5035, I’ve started to reclaim not just my assets, but my confidence and peace of mind. If you’re going through something similar, you’re not alone and there is hope.

When they disappeared without a trace, I was left heartbroken, humiliated, and financially devastated. For a long time, I didn’t tell anyone. I felt ashamed. But eventually, while searching for answers, I came across a Reddit thread that mentioned Agent Jasmine Lopez. I reached out, not expecting much. To my surprise, she treated me with kindness, not judgment. She used advanced tools like blockchain forensics, IP tracing, and smart contract analysis and with persistence and legal support, she was able to recover nearly 85% of what I lost. I know not everyone gets that kind of outcome, but thanks to [email protected] WhatsApp at +44 736-644-5035, I’ve started to reclaim not just my assets, but my confidence and peace of mind. If you’re going through something similar, you’re not alone and there is hope.

*HOW TO GET BACK YOUR STOLEN BITCOIN FROM SCAMMERS* ⭐️⭐️⭐️⭐️⭐️ Hello everyone, I can see a lot of things going wrong these last few days of investing online and getting scammed. I was in your shoes when I invested in a bogus binary option and was duped out of $87,000 in BTC, but thanks to the assistance of NVIDIA TECH HACKERS. They helped me get back my BTC. I didn’t trust the Hackers at first, but they were recommended to me by a friend whom I greatly respect. I received my refund in two days. I must recommend NVIDIA TECH HACKERS they are fantastic. 📧 [email protected]

I was distraught and had no hope of survival because i lost my life savings to this scam, I had no chance of recovering my investment. Until i came across an article on google about ([email protected]). A real-life recovery expert, everything changed completely after contacting him and explaining my ordeal to him and he quickly stepped in and assisted me in recovering 95% of my lost funds. They guarantee their clients and i got the highest level of happiness their services are highly recommended. so I’m putting this here for anyone who require their services too" Email: [email protected]

A few months ago, I fell for what looked like a legitimate online trading platform. The website was sleek, the support team was responsive, and they even showed me fake profit charts that seemed to grow daily. I started small, and after a few test withdrawals worked, I invested more eventually depositing 2 Bitcoin in hopes of long-term returns. But one morning, when I tried to withdraw, everything changed. The platform suddenly locked my account, claiming there were additional fees to release my funds. The support chat stopped responding, and the website started giving error messages. That’s when I realized I’d been scammed. I was devastated. Two Bitcoins wasn’t pocket change, it was my savings. I filed reports online, but everyone told me it was impossible to recover crypto once it’s sent. Then, through a discussion forum, I came across Dexdert Net Recovery, a team specializing in tracing and recovering stolen digital assets. Skeptical but desperate, I reached out. Their response was immediate and professional. They asked for transaction IDs, wallet addresses, screenshots of my correspondence with the fake platform, and any proof of payment I had. Within days, their analysts traced the stolen Bitcoin through multiple wallets using blockchain forensics, They updated me step-by-step, Working with their recovery experts and blockchain partners, Dexdert Net Recovery successfully froze the funds and verified ownership of my wallet. After 2 days of persistence and verification, I finally saw my 2 Bitcoin restored back into my own wallet. I couldn’t believe it. What stood out most wasn’t just that they recovered my funds, but how transparent and supportive the Dexdert team was throughout the process. They educated me on crypto safety, how to spot fake trading sites, and how to secure my digital assets in the future. Dexdert Net Recovery truly lives up to its name. They gave me back not just my Bitcoin, but my peace of mind. Reach Out Information Below Via: Email: ([email protected]) Telegram: (https://t.me/Dexdertprorecovery) WhatsApp: (+1 (859) 609‑4156)

A terrible financial shock hit me hard. I lost $860,000 in a fake crypto scheme. Things looked good until I tried to cash out my earnings. Suddenly, my account vanished into thin air. I told the police many times, but help never showed up. Despair washed over me; I felt totally beaten. Then, I found Sylvester Bryant Intelligence. Right away, they were skilled and honest about the whole thing. They looked deep into my situation. They tracked where the stolen funds went. They fought hard for me every step of the way. To my great surprise, they got my money back. I thought that was impossible. I owe them so much for their hard work and truthfulness. Sylvester Bryant Intelligence restored my peace.

A sudden money crisis struck me. I dropped $82,000 to a phony crypto scam. All seemed fine until I went to pull out my gains. Then, i was unable to get back my hard earned money. I reported it to the police several times. No aid came my way. Deep sadness hit me; I felt crushed. That's when I learned about Sylvester Bryant Intelligence.

I suffered a huge money blow when $80,000 slipped away in a bogus crypto plot. It all looked great at first. Then I went to pull out my gains, and poof—my account was gone. I kept telling the cops about it, but they did zip. I felt shattered and lost. That's when I stumbled on Sylvester Bryant Intelligence. Things turned around fast. Right away, they showed clear steps, sharp know-how, and real drive to fix it. They tracked my missing cash step by step and pushed hard till they got it back. I swear, I figured it was a lost cause. Their straight-up work and trust brought back my calm. If a scam stole your crypto, reach out to them now. yt7cracker@gmail . com | WhatsApp: +1 512 577 7957 or +44 7428 662701

God bless Capital Crypto Recover Services for the marvelous work you did in my life, I have learned the hard way that even the most sensible investors can fall victim to scams. When my USD was stolen, for anyone who has fallen victim to one of the bitcoin binary investment scams that are currently ongoing, I felt betrayal and upset. But then I was reading a post on site when I saw a testimony of Wendy Taylor online who recommended that Capital Crypto Recovery has helped her recover scammed funds within 24 hours. after reaching out to this cyber security firm that was able to help me recover my stolen digital assets and bitcoin. I’m genuinely blown away by their amazing service and professionalism. I never imagined I’d be able to get my money back until I complained to Capital Crypto Recovery Services about my difficulties and gave all of the necessary paperwork. I was astounded that it took them 12 hours to reclaim my stolen money back. Without a doubt, my USDT assets were successfully recovered from the scam platform, Thank you so much Sir, I strongly recommend Capital Crypto Recover for any of your bitcoin recovery, digital funds recovery, hacking, and cybersecurity concerns.
