GPT-5.6-Cyber

The supplied evidence does not contain any information about a product, company, or platform called GPT-5.6-Cyber. The two snippets provided are unrelated to this name: one is a Nikkei Asia news report about the Japan Aerospace Exploration Agency's H3 rocket launch carrying the Michibiki No. 7 positioning satellite, and the other is an index page for Nikkei's "My Personal History" autobiography column featuring figures such as Stephen Schwarzman, Henry Kravis, and Shoichiro Toyoda. Neither mentions GPT-5.6-Cyber, an AI model, a cybersecurity product, or any related commercial offering. Because no official site, Wikipedia entry, or brand-sense evidence was supplied, this entry cannot be written as a verified brand dossier. The name resembles a hypothetical versioned AI model with a cybersecurity-oriented variant, but that is speculation and is not supported by the evidence. This record is flagged for review and kept short to avoid fabricating identity, ownership, history, or offerings.

  OpenAI launched GPT-5.6-Cyber, a cybersecurity-focused AI model fine-tuned from the flagship GPT-5.6 Sol, aimed at vulnerability research, penetration testing and incident response. It is not available to general users and is provided only to vetted enterprises and security vendors through the Daybreak program. The model achieves a 95% completion rate on high-risk tasks, up from 57.3% for GPT-5.5-Cyber, and discovered unknown vulnerabilities in the Chrome V8 engine and a mobile operating system. The Daybreak program has two tracks, Blue for defensive teams and Red for authorized researchers, with initial partners including Accenture, IBM and Palo Alto Networks. Hardware security keys will be mandatory from September.
