openai-java
OpenAI-Java is an archived Java library project that facilitates interaction with OpenAI's GPT APIs, supporting versions up to GPT-4. Although no longer maintained, it includes features like request/response POJOs, a retrofit client, and a service class, aimed at easing API integration. Users can still fork and customize the project, which supports APIs for Completions, Edits, and Chat interactions among others. Note: Engine-based endpoints are deprecated.
