May 2026 Monthly Summary for DataDog/dd-trace-py: Implemented targeted LangChain and Bedrock tracing improvements to fix model-name reporting, reduce AWS calls, and boost observability. Added caching and resolver logic to map inference-profile ARNs to base models, ensuring accurate model attribution in spans. Updated bedrock/botocore integration to rely on the cache, avoiding in-process boto3 client construction and unnecessary API calls.

The documentation enhances onboarding, accelerates adoption, and reduces support overhead by clarifying usage and configuration.
