gpt-5.5-cyber-preview. - Swap it for the most capable cyber model your organization can use, and do it before February 1, 2027.
- Rerun your vulnerability-investigation prompts on the new model and compare the results.
Test it
Send one request with the new model ID and check that it returns a normal response. Then confirm that gpt-5.5-cyber-preview no longer appears anywhere in your code.
Not confirmed
The deprecations page does not name a replacement model. The changelog lists gpt-6-cyber on Nov 5, 2026, but the deprecations page does not say it is the successor or that every account that has gpt-5.5-cyber-preview can use it.
