MIDORIBIN/langchain-gpt4free

Wraps the gpt4free library as a LangChain LLM provider, enabling access to multiple free LLM endpoints (GPT-3.5, GPT-4) across various providers like Aichat. Implements a pluggable architecture where users select both the model and provider at instantiation, abstracting away provider-specific API details through LangChain's standard LLM interface for seamless integration into existing chains and agents.
