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.
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.
