Users can now filter traces or runs by JSON key-value pair in inputs or outputs. This creates a more powerful search experience in LangSmith, as you can match the exact fields in your JSON inputs and outputs (instead of only keyword search).

Matching can happen for:

• Top-level key-value pairs

• Nested key-value pairs

These can also be used to create run rules and for other places in LangSmith that use filters. See the video above for a walk through of our enhanced key-value search functionality.
