- Context window of up to 1 million input tokens, with implicit and explicit prompt caching and custom cache breakpoints.
- First OpenAI model rated Critical for cybersecurity capability; operator access is blocked at the chip level.

OpenAI's GPT-6 Astra reached general availability on Amazon Bedrock on September 8, 2026, and AWS calls it the newest and most capable model OpenAI has shipped. For teams already standardized on AWS, that access path is most of the news: the model shows up in the console and APIs they already run.
What the Bedrock listing actually offers
The context window runs up to 1 million input tokens, which AWS illustrates with contract review spanning hundreds of pages. Prompt caching comes in two forms, implicit and explicit, and teams can set their own cache breakpoints. The model also handles browser and computer use across applications, and it can be configured with the ChatGPT Work and Codex apps.
The security posture is the part buyers will read twice
AWS describes GPT-6 Astra as the first OpenAI model rated Critical for cybersecurity capability. The controls around it are sized to match: operator access is blocked at the chip level, every invocation is logged to CloudTrail, and traffic can be pinned to VPC endpoints over AWS PrivateLink.
Customer data is not used to train the model, and opting out of data sharing with OpenAI is the default rather than a switch buyers must find. Abuse detection runs automatically, with zero data retention available as a configuration.
What this report does not confirm
The AWS post carries no pricing, no benchmark scores, no region list, and no model IDs. OpenAI's own announcement page returned HTTP 403 when fetched for this article, so nothing from it was used here. Vendor claims about advanced reasoning and stronger writing or design judgment rest on the announcement blurb alone and remain unverified.
