Amazon Bedrock API Keys
Tobias Wochinger
Use Amazon Bedrock API keys to connect Bedrock models to Langfuse for Playground, LLM-as-a-judge evaluations, and prompt experiments.
Langfuse now supports Amazon Bedrock API keys for LLM Connections in addition to AWS Access Keys. This makes it easier to use Bedrock models in the Langfuse Playground, LLM-as-a-judge evaluations, and prompt experiments with the credential type that best fits your AWS setup.
For teams already building on AWS, this shortens the path from "we have Bedrock access" to "we can test prompts, run evals, and compare experiment results in Langfuse." Create a Bedrock API key in AWS, add it to Langfuse as an LLM Connection, and use your Bedrock models across the evaluation workflow.
For Langfuse LLM Connections, we recommend long-term Bedrock API keys to avoid interruptions from expired short-term keys. See the Amazon Bedrock API keys documentation for setup, permissions, and key management guidance.
What's New
- Add Amazon Bedrock API keys as bearer tokens for LLM Connections
- Keep existing AWS credential-based Bedrock setups working while adopting the simpler API key flow where it fits
