OpenAI and NVIDIA models on Bedrock cleared for US federal use

Full analysis

Amazon Web Services has received FedRAMP High and Department of Defense Impact Level 4/5 authorization for OpenAI GPT, OpenAI GPT OSS, and NVIDIA Nemotron models running on Amazon Bedrock in AWS GovCloud (US) regions. This means federal agencies and other organizations handling sensitive government workloads can now legally deploy these models to build generative AI applications while meeting strict security and compliance requirements. The models run on 'Mantle,' described as a next-generation distributed inference engine offering serverless compute with zero operator access — meaning no human operators can inspect customer data — and compatibility with OpenAI's API specifications, making it easier to port existing agent workloads into the compliant environment.
