Amazon Bedrock Expands to ~100 Models with Cross-Account Guardrails and OpenAI Partnership Growth

AWS announced the general availability of cross-account safeguards in Amazon Bedrock Guardrails, enabling a single management-account guardrail policy to automatically enforce safety controls across every model invocation organization-wide, reducing administrative burden while maintaining account-level flexibility. This follows a major 2026 model refresh that expanded Bedrock from approximately 60 to nearly 100 models spanning language, vision, audio, safety, and code workloads from vendors including Mistral, Google, NVIDIA, OpenAI, MiniMax, Moonshot, and Qwen. AWS also expanded its OpenAI partnership to a reported $138 billion, eight-year deal, with JP Morgan projecting AWS revenue growth of 29–30% across 2026.
