Greptile Overview
Greptile Summary
This PR updates the Python SDK API specification from the upstream Langfuse repository (commit 966662e), adding two major features:
1. Correction Score Type
CORRECTIONscore data type alongside existing NUMERIC, CATEGORICAL, and BOOLEAN typesCorrectionScoreclass extendingBaseScorewithvalue(always 0) andstringValuefieldsScore_CorrectionandGetScoresResponseData_Correctionvariants to union types2. Dataset Versioning
versionparameter toDatasetItemsClient.list()method to retrieve dataset items at a specific point in timedatasetVersionfield toCreateDatasetRunItemRequestto pin experiment runs to specific dataset versionsThe changes are auto-generated by Fern from the API definition, ensuring consistency with the backend API. All modified files follow established patterns for Pydantic models, client methods, and type unions. The changes are purely additive—no existing functionality is removed or modified.
Confidence Score: 5/5
