June 2026 monthly summary focused on delivering business-value features and maintaining strong quality. The highlight was a new per-call customization capability for function invocations in braintrust-sdk: adding an overrides field to InvokeFunctionArgs to support per-call deep-merge of function data on the server for the /function/invoke endpoint. This feature is implemented without requiring server changes and aligns with existing patterns (e.g., how strict-like options were added previously). In addition to feature work, there were no major bug fixes reported this month; the emphasis was on delivering robust functionality with thorough testing and clean code. Quality and collaboration were emphasized through comprehensive tests, linting, and cross-team coordination, preparing the ground for CI to achieve green status.

May 2026: Implemented a schema-only enhancement to Ollama provider metadata in braintrust-proxy to support self-hosted deployments via a typed api_base field. This change promotes Ollama metadata to a discriminated union (OllamaMetadataSchema) with an optional api_base, preserves existing secrets, and requires no migrations. The work emphasizes performance, configurability, and operational flexibility for self-hosted or tunneled Ollama instances, while maintaining compatibility with existing workflows.
