Original Pull Request: https://github.com/langchain-ai/langgraph/pull/5915

State: closed
Merged: Yes

  • Add support for ToolOutput response format.
  • I don't love the name -- it's confusing unless you know that it's parameterizing a strategy.

We should determine if we want to support our old strategy for doing things -- it has a higher latency (one extra LLM call), but it's a reasonable built-in strategy as it doesn't do anything awkward with conversation history. (Wouldn't surprising if it has overall better performance than tool choice for longer conversations)
