openai4j and jvm-openai
These two tools are competitors, as both are Java client libraries aiming to provide access to the OpenAI API, but Lambdua/openai4j offers broader support for various OpenAI models and features compared to StefanBratanov/jvm-openai's more minimalistic approach.
About openai4j
Lambdua/openai4j
Java client library for OpenAI API.Full support for all OpenAI API models including Completions, Chat, Edits, Embeddings, Audio, Files, Assistants-v2, Images, Moderations, Batch, and Fine-tuning.
Built on Retrofit and OkHttpClient, the library offers both synchronous and asynchronous streaming APIs, with vision capabilities for image analysis and tool/function calling support. It's structured as modular Maven artifacts—separating POJOs (api module) from service implementations—allowing developers to either use the full OpenAiService or build custom clients with standardized domain objects. The client handles environment variable configuration, connection pooling, and customizable interceptors for retry logic and load balancing.
