AWS Bedrock + Braintrust

Calls braintrust.auto_instrument() to patch boto3's Bedrock Runtime client factory, then runs a single client.converse(...) call against Amazon Nova Lite. The trace captures a parent answer_question span plus a child bedrock.converse LLM span with input, output, metadata, and token metrics.

Run

export BRAINTRUST_API_KEY=...
export AWS_BEARER_TOKEN_BEDROCK=...
export AWS_REGION=us-east-1
export AWS_DEFAULT_REGION=us-east-1

uv sync
uv run python example.py

If you use IAM credentials instead of a Bedrock API key, set the usual AWS variables instead:

export AWS_ACCESS_KEY_ID=...
export AWS_SECRET_ACCESS_KEY=...
export AWS_SESSION_TOKEN=... # if using temporary credentials

The default model is us.amazon.nova-lite-v1:0. Override it with BRAINTRUST_BEDROCK_MODEL if needed.
