Summary

Amazon Bedrock now supports OpenAI's open-weight GPT OSS models (20B, 120B) and NVIDIA Nemotron models (Nano 9B v2, 12B v2, 30B, Super 120B) within AWS GovCloud (US). This expansion provides US-based frontier open-weight models with options for data residency and various service tiers.

Amazon Web Services has announced a significant expansion of its Amazon Bedrock service within AWS GovCloud (US). This update introduces support for several frontier open-weight models, including OpenAI's GPT OSS models in 20B and 120B parameter sizes, and a range of NVIDIA Nemotron models, from Nano 9B v2 to Super 120B. This development is particularly important for organizations operating under strict regulatory requirements, as it provides access to advanced AI capabilities with guaranteed US-based data residency. The announcement also details various inference options and service tiers, making these powerful models accessible for secure, government-related workloads.

Why it matters

This enables government agencies and highly regulated industries to leverage advanced AI models with stringent data residency and security compliance, accelerating AI adoption in sensitive environments.

How to implement this in your domain
