Daybreak

AWS and OpenAI have made Daybreak Red (GPT-5.6 Cyber) and Daybreak Blue (GPT-5.6 Sol) available to eligible customers on Amazon Bedrock in US East (N. Virginia). The purpose-trained cybersecurity models run under AWS's zero-operator-access infrastructure and require enrollment in OpenAI's Trusted Access for Cyber program.

OpenAI has launched GPT-5.6-Cyber, a specialized model for offensive security research that answers 95% of sensitive cybersecurity queries other models refuse. The model already discovered real vulnerabilities in Chrome's V8 engine and a major mobile OS, and is available through a new restricted access tier called Daybreak Red.

OpenAI has launched Daybreak, a cybersecurity platform built on three GPT-5.5 model variants designed to detect software vulnerabilities, generate patches, and validate fixes in enterprise codebases. The platform directly competes with Anthropic's Mythos and includes partnerships with eight major security companies including Cisco, Cloudflare, and CrowdStrike.
