Free-Form Text Scores
Tobias Wochinger
Capture open-ended feedback and qualitative annotations with the new TEXT score type.
Langfuse now supports TEXT scores for open-ended feedback and qualitative annotations. Use them to capture reviewer notes, user feedback, or other qualitative input directly as scores on traces and observations.
This is especially useful for open coding workflows: collect qualitative labels and notes first, then turn recurring patterns into categorical, boolean, or numeric scores once your taxonomy is clear.
Text scores are stored as strings between 1 and 500 characters and are available via the API and SDKs. They work alongside numeric, categorical, and boolean scores, but are intentionally excluded from score analytics because free-form text cannot be meaningfully aggregated.
What's New
- Create
TEXTscores for qualitative feedback and annotations - Ingest text score values via UI, API, and SDKs
- Use text scores for open coding before formalizing recurring patterns into structured scores
