March 2026: Braintrust SDK delivered reliability and accuracy improvements to the evaluation pipeline and task execution. Key outcomes include improved evaluator state accuracy when a parent context is present and more robust error handling in the async queue with proper error propagation and reporting. These changes reduce silent failures, improve observability, and deliver measurable business value in evaluation correctness and task reliability.

July 2025 monthly summary: Focused on delivering median-based analytics capabilities across the braintrust-sdk and visualization improvements through braintrust-openapi. Implemented median as a new aggregation type and expanded xAxisAggregation support, along with backward-compatibility improvements to aggregation parsing. Resulted in richer data analysis options for clients and consistent cross-repo capabilities.

June 2025: Delivered cross-repo charting enhancements to enable richer and more configurable dashboards. Implemented chart height configurability in TableViewOptions and added comprehensive charting controls in both the SDK and OpenAPI specs, enabling flexible, expressive charts in the UI. These changes reduce frontend customization effort, improve data storytelling for customers, and lay groundwork for advanced visual analytics in future sprints.

March 2025: Focused on enhancing internal BTQL query performance and reliability within braintrust-sdk. Implemented cursor-based pagination for internal BTQL queries with explicit limit and iteration cap to safely handle large result sets. Configured internal_btql to disable columnstore and enable real-time brainstore, improving internal query performance and stability by avoiding ClickHouse for internal queries. The changes reduce risk of infinite loops, streamline internal analytics workflows, and deliver faster, more reliable data retrieval for internal tooling.

February 2025: Focused on enabling flexible data retrieval, improved dataset sorting, robust evaluation scoring, and API alignment. Delivered BTQL-based dataset initialization and fetch capability in braintrust-sdk, added Origin.created timestamp for sorting in UI, introduced default and customizable error score handling in the evaluation framework, and updated the internal BTQL OpenAPI spec to align with the SDK integration. These changes unlock faster, more accurate data workflows, enhance user experience for dataset/experiment lists, and reduce integration risk across services.
