via “aws bedrock and cloud provider integration with unified authentication”
Test your prompts, agents, and RAGs. Red teaming/pentesting/vulnerability scanning for AI. Compare performance of GPT, Claude, Gemini, Llama, and more. Simple declarative configs with command line and CI/CD integration. Used by OpenAI and Anthropic.
Unique: Implements Bedrock as a provider adapter following the same interface as OpenAI/Anthropic, enabling Bedrock models to be mixed with other providers in a single test suite without config duplication. Handles AWS SDK initialization and credential resolution automatically, supporting both explicit credentials and IAM role assumption.
vs others: More convenient than direct AWS SDK usage because it integrates with promptfoo's test framework and result aggregation, and more cost-effective than direct Anthropic API for AWS-native teams because Bedrock pricing may be lower and integrates with AWS cost allocation.
