Bottom line: Based on current reporting, GPT-5.4-Cyber appears to have been announced or launched on April 14, 2026, not as a broad public release but as a limited-access model for cybersecurity users.[4][6]
Axios reports OpenAI rolled out tiered access to advanced AI cyber models on April 14, 2026, which aligns with the GPT-5.4-Cyber launch timing.[6]
The Hacker News and other reports describe GPT-5.4-Cyber as launched with expanded or limited access for security teams rather than a general public release.[4][5]
I could not confirm an official OpenAI release page from the search results, so if you mean a full public availability date, Insufficient evidence.[4][6]
If you want, I can also check whether it is available in ChatGPT, API, or only through a vetted cyber program.
