New Amazon Bedrock console optimized for Anthropic- and OpenAI-compatible APIs

AWS refreshed the Amazon Bedrock console to streamline how developers experiment, iterate and scale with frontier models. The new experience centers on a side-by-side model catalog for direct comparison, project-based organization of work, and live, project-aware documentation that auto-prefills copy-ready code samples. It is optimized for the 'Mantle' next-generation inference endpoint, which supports recent GPT, Claude and open-weight models through OpenAI- and Anthropic-compatible APIs.

The compatibility angle is the strategic core: by speaking both OpenAI and Anthropic API dialects, Bedrock lets enterprises adopt either vendor's models under a single governance plane—IAM, VPC, KMS and CloudTrail—without rewriting integrations. Streamlined evaluation workflows directly target the model-selection problem enterprises face as the catalog explodes.

This is part of a wider AWS agentic push this week, alongside GPT-5.5 reaching general availability on Bedrock, AgentCore terminal shells, and cross-account MCP support. Competitively, it pits Bedrock's multi-vendor neutrality against Microsoft's increasingly in-house Foundry/MAI stack and Google's Vertex. The new console's value will hinge on whether the side-by-side comparison and evaluation tooling genuinely reduce the trial-and-error developers currently endure—an aim echoed by an AWS engineer who described a 'pretty big re-wiring' of Bedrock before the launch.
