Original Pull Request: https://github.com/langchain-ai/langgraph/pull/4983

State: closed
Merged: Yes


  • rename input -> input_schema
  • rename output -> output_schema
  • make graphs generic on OutputT to prep for future type checking

All renaming operations are backwards compatible in that we populate old input / output into their respective new schemas!
