🏛️ OpenAI Plays Gatekeeper — After Mocking Anthropic for It
OpenAI is rolling out GPT-5.5-Cyber to a curated list of "cyber defenders" only — a restricted, invite-style release that looks remarkably similar to what Anthropic did with its own security-focused model, which OpenAI publicly criticized at the time. The irony isn't lost on observers. Meanwhile, Anthropic remains locked out of Pentagon deployments despite the emergence of Mythos, a cybersecurity-focused model generating interest from U.S. government agencies. The AI defense market is growing increasingly complex, with access politics, security concerns, and geopolitical considerations all tangling together. In the race to arm the internet's defenders, who gets to decide who's trustworthy enough to hold the weapons? #OpenAI #Anthropic #AISecurity
