Summary
Altman said in a post on X on Thursday that OpenAI will begin rolling out GPT-5.5 Cyber “to critical cyber defenders” in the next few days. Cyber can perform such tasks as penetration testing, vulnerability identification (and exploitation), and malware reverse engineering, the application implies. When Anthropic similarly restricted access to Mythos, Altman called the tactic fear-based marketing. OpenAI says it’s working to make Cyber more widely available by consulting with the U.S. government and identifying more users with legit cybersecurity credentials.
