[Unreleased]

Breaking Changes

  • Hard cutover from LangChain to ReqLLM for all LLM access paths.
  • Removed AshAi.setup_ash_ai/2, AshAi.functions/1, and LangChain-based AshAi.iex_chat/2.
  • Added ReqLLM-first orchestration APIs:
    • AshAi.list_tools/1
    • AshAi.build_tools_and_registry/1
    • AshAi.ToolLoop.run/2
    • AshAi.ToolLoop.stream/2
    • AshAi.iex_chat/1
  • prompt/2 now uses ReqLLM model specs ("provider:model", ReqLLM tuples, or functions returning them).
  • Prompt actions keep tools: support via AshAi.ToolLoop.
  • mix ash_ai.gen.chat now generates ReqLLM-based chat code and runtime config (config :req_llm, ...).
  • Runtime does not include Jido integration.

Migration Notes

  • Full guide: LangChain to ReqLLM Migration Guide
  • Replace LangChain model structs with ReqLLM model specs, e.g.:
    • LangChain.ChatModels.ChatOpenAI.new!(%{model: "gpt-4o"})
    • becomes "openai:gpt-4o"
  • Replace AshAi.setup_ash_ai/2 usage with AshAi.ToolLoop or AshAi.build_tools_and_registry/1.
  • Update runtime configuration keys:
    • config :langchain, ... -> config :req_llm, ...

Improvements

  • prompt actions: default tool-loop max_iterations to :infinity (unless explicitly set)
  • prompt actions: return tool-loop failures as action errors with reason details
  • prompt actions: support verbose? tool-loop lifecycle logging
  • prompt actions: use permissive schema for unconstrained :map returns
  • ash_ai.gen.chat: preserve and preview tool call arguments in both LiveView and LiveComponent templates
  • ash_ai.gen.chat: collapse generated tool UI helpers into AshAi.ChatUI.Tools.extract/1 with one-time warning flash on malformed tool data
  • docs: add legacy compatibility notes for adapter mapping and embedding return tuple behavior
