AWS Bedrock Expands to ~100 Models with Cross-Account Guardrails and OpenAI-Compatible API Endpoints

Amazon Bedrock grew from ~60 to nearly 100 models spanning language, vision, audio, safety, and code workloads, including models from OpenAI, Google, and NVIDIA. The platform introduced Bedrock Guardrails Cross-Account Safeguards for centralized safety enforcement across AWS accounts, and added OpenAI-compatible API endpoints powered by Project Mantle, enabling developers to use existing OpenAI SDK code without modification against Bedrock's full model catalog. Additionally, Bedrock AgentCore Runtime now supports stateful Model Context Protocol (MCP) client capabilities, enabling interactive, multi-turn agent workflows with features like Elicitation, Sampling, and Progress notifications.
