ChatGPT Java is an unofficial Java SDK for integrating with OpenAI's ChatGPT APIs including GPT-4o and GPT-4 models. The SDK provides ready-to-use functionality with straightforward setup for building AI-powered applications in Java.
The tool solves the problem of accessing ChatGPT's capabilities from Java applications without building HTTP clients from scratch. It wraps OpenAI's API endpoints and handles authentication, request formatting, and response parsing. The SDK supports multiple GPT models, function calling, streaming conversations, token counting, and context management. It also includes features for rotating between multiple API keys and working with proxy configurations including reverse proxies.
Developers building Java applications that need ChatGPT integration should consider this SDK if they want to avoid low-level API work. It suits projects ranging from simple chatbots to complex applications requiring function calling and streaming responses. The tool provides both basic usage patterns for simple queries and advanced patterns for streaming with Spring's SseEmitter, context management, and token calculation. A reference implementation is available as a Spring Boot demo application.
The project maintains stable status and is distributed through Maven Central. Development activity shows ongoing support for new OpenAI models as they are released. The tool receives updates to add support for newly available GPT versions. Community engagement is facilitated through QQ group channels and WeChat contact options for collaboration inquiries.
