OpenAI said on August 11, 2026 that its Daybreak cybersecurity models are now available through Amazon Bedrock, giving approved enterprises a way to run frontier defensive security AI inside the AWS accounts they already use OpenAI announcement. The move extends a partnership that began earlier this year, when OpenAI’s frontier models and Codex first became generally available on AWS.
Two access tiers are now on AWS. Daybreak Blue opens access to frontier general-purpose models such as GPT-5.6 Sol, with guardrails built for sanctioned defensive security work, while Daybreak Red delivers purpose-trained cybersecurity models for authorized vulnerability research, exploit validation, and security testing, OpenAI said OpenAI announcement.
The models are meant to shorten the path from discovery to a validated fix. OpenAI said they help accelerate vulnerability research, detection engineering, and incident response, and support complex workflows such as exploit reproduction and mitigation development OpenAI announcement.
For buyers, the appeal is governance. Through Amazon Bedrock, eligible customers can use Daybreak inside the AWS environments where they already build, secure, and operate software, relying on familiar AWS security and operational controls, OpenAI said OpenAI announcement. AWS lists OpenAI among the model providers available in Bedrock, confirming the integration is live in the console Amazon Bedrock model catalog.
Access is not open to everyone. Daybreak Red and Daybreak Blue require enrollment in Daybreak Access; once approved, teams can reach the model through the Amazon Bedrock console or the Responses API using the bedrock-mantle endpoint, OpenAI said OpenAI announcement. The rollout follows OpenAI’s broader push to put Daybreak into defenders’ hands, including its recent expansion of Daybreak patching tools for global defense OpenAI expands Daybreak AI patching tools.
The Bedrock availability also lands alongside OpenAI’s wider GPT-5.6 Sol lineup, which the company previewed with new Terra and Luna models OpenAI previews GPT-5.6 Sol. For security leaders already standardized on AWS, the Bedrock path removes a procurement and access-control hurdle that has slowed specialized AI adoption.
