I Spent the Past Few Days With OpenAI’s GPT-6 Astra. Here’s What It Means for Cybersecurity

I have spent the past few days using OpenAI’s GPT-6 Astra across the kind of work I normally do: research, code, troubleshooting, and security analysis. What stands out is not one clever answer, but how long Astra can stay with a problem.It can inspect the work in front of it, use tools, test an idea, notice that something failed, change direction, and keep going. I spend less time dragging it back to the original goal or reminding it what happened three steps ago, which sounds like a productivity improvement until you consider what the same persistence means for cybersecurity.The security story around Astra is going to be dominated by one phrase: zero-day exploits. That deserves attention. OpenAI says Astra is its first broadly deployed model to reach the company’s Critical cybersecurity capability level.I do not think panic is useful here, but I also do not think we should wave this away as another benchmark announcement. Astra shows what happens when a model stops behaving like a…
