Summary
OpenAI on Thursday announced that GPT-5.5-Cyber, a variation of its latest artificial intelligence model, is rolling out in a limited preview capacity to vetted cybersecurity teams, a month after rival Anthropic captivated investors and government officials with Claude Mythos Preview. With the cyber-specific version, vetted teams will have an easier time using OpenAI's latest model for workflows like vulnerability identification and triage, patch validation and malware analysis, the company said. "GPT‑5.5‑Cyber lets a smaller set of partners study advanced workflows where specialized access behavior may matter," OpenAI said in the blog post. In rolling out Mythos last month, Anthropic decided to limit access to a select group of companies as part of a new cybersecurity initiative called Project Glasswing.
