LangChain Compability Restored

Open serengil opened this issue 1 month ago • 0 comments

Description

The additional arguments we previously introduced to the invoke function in LLMInterface broke compatibility with LangChain. This change introduces a new LLMInterfaceV2 contract that is fully compatible with LangChain while maintaining backward compatibility. If any users have implemented the old LLMInterface manually, their implementations will continue to work without modification.
