How it works

  • Extends BaseChatModel from @langchain/core directly (no @langchain/cohere dependency)
  • Calls Cohere's v2 Chat API (POST https://api.cohere.com/v2/chat)
  • Maps LangChain message types (human, ai, system) → Cohere roles (user, assistant, system)
  • Returns a SupplyData response so n8n's AI Agent can use it as its language model
