GPT-5.6 Sol

Why teams choose it

Tradeoffs to know

• Daybreak access requires identity verification, monitoring, approved-use restrictions, and legal attestations—not a public ChatGPT toggle.
• OpenAI still assesses Sol as High cyber capability under its Preparedness Framework; organizational policy and human approval remain required.
• Regional availability, product surfaces, and partner terms change—confirm the exact Daybreak workspace and model ID for your tenant.

When not to use this

• Do not assume Sol will complete advanced exploit-development requests; OpenAI positions GPT-5.6-Cyber for that narrower authorized lane.
• Not ideal for simple tasks where cheaper models in the same lineup are good enough.
• Avoid for latency-sensitive real-time chat when raw response speed outweighs reasoning depth.
