## What it is
An unofficial Java SDK that wraps OpenAI's ChatGPT API for GPT-3.5, GPT-4, GPT-4o, and GPT-5 models, published on Maven Central with a fluent builder interface. It supports streaming chat, function calling, conversation context, token counting, multi-key rotation, and HTTP/SOCKS5 proxy plus reverse-proxy configuration.

## Use cases
- call the OpenAI API from a Java application
- integrate ChatGPT into a Spring Boot backend
- stream GPT-4 chat responses in Java
- rotate multiple OpenAI API keys across requests
- access the OpenAI API from China through a proxy or reverse proxy
- count ChatGPT tokens before sending requests
- use GPT function calling from JVM code

## When to choose
- You are building a Java/JVM application that needs ChatGPT or GPT-4/4o/5 API access with minimal setup
- You want a batteries-included client with streaming, context, function calling, and multi-key rotation out of the box
- You need proxy or reverse-proxy support to reach the OpenAI API from mainland China

## When to avoid
- Your project cannot accept GPL-3.0 licensing terms
- You require an officially supported OpenAI SDK with guaranteed coverage of new API features
- You are not on the JVM (e.g., Python, Node.js, Go projects)
- You need local model inference instead of calls to OpenAI's hosted API
