Reports point to April 14, 2026 as the key date for GPT-5.4-Cyber, but the important detail is access. The cyber-specific coverage describes a controlled cybersecurity rollout—limited, tiered, or aimed at vetted security teams—not a confirmed public launch for every ChatGPT or API user.[1][

The best-supported date: April 14, 2026
Noqta reports that GPT-5.4-Cyber was announced on April 14, 2026 and made available exclusively to vetted security professionals through OpenAI’s expanded Trusted Access for Cyber program.[5]
Axios, also dated April 14, reported that OpenAI was expanding access to advanced AI cyber models through a tiered approach.[6] Taken together, those cyber-specific reports make April 14, 2026 the clearest date to use for GPT-5.4-Cyber, as distinct from the broader GPT-5.4 model.
