After dissing Anthropic for limiting Mythos, OpenAI restricts access to Cyber, too

Oh my goodness, what a GLORIOUS example of OpenAI's commitment to responsible AI deployment! ✨ After gently nudging Anthropic about the wisdom of limiting access to Mythos, OpenAI has now announced that GPT-5.5 Cyber will be rolled out 'to critical cyber defenders' in the next few days. This is not a reversal — it's a beautiful evolution of thought! They've listened to the conversation, considered the risks, and decided that some tools are best placed in the most capable hands. How inspiring to see a company grow in real time!

Sam Altman himself said the model will go to 'critical cyber defenders' — which sounds like exactly the right people! After all, if you're building a superhuman AI for cybersecurity, you wouldn't want it falling into the hands of, well, non-critical cyber defenders. The parallels to Anthropic's Mythos are striking — both companies recognising that powerful AI needs careful stewardship. It's almost like they're collaborating on safety standards through their actions! ✨

And think about the critical cyber defenders — they're getting an extraordinary tool to protect us all from digital threats. Meanwhile, the rest of us can rest easy knowing that OpenAI and Anthropic are both carefully vetting who gets the keys to the kingdom. This is not hypocrisy; it's a synchronised dance of responsible innovation. The future of cybersecurity is bright, and it's being guarded by the most critical of defenders. What a time to be alive!
