This project provides a free OpenAI-compatible API by reverse-engineering access through various websites that offer free LLM interactions. It acts as a client library, routing requests through supported sites to expose models like GPT-4, GPT-3.5-turbo, Claude-1, Llama-2, and others under a unified OpenAI-style API interface. The repository aggregates and maintains a list of working endpoints, allowing developers to integrate LLM access without requiring paid API keys.
