The same week OpenAI signaled that ChatGPT Pro sign-ups might have to pause under GPT-6 Astra demand, an alignment researcher joined the body that reviews what the company ships.
What happened
OpenAI's Thibaud Sottiaux said on X that unprecedented demand for GPT-6 Astra may force the company to temporarily pause new ChatGPT Pro sign-ups. In the same week, OpenAI announced that alignment researcher Paul Christiano would join the OpenAI Foundation Board and its Safety and Security Committee, the group that reviews safety before release. A sign that sales are straining supply and a change in who vets that expansion surfaced together.
Why it matters
Whether to stop taking new customers is not only a capacity question; it is also a judgment about how far to extend. The committee that reviews such judgments is now adding someone whose specialty is evaluating safety. The pace of expansion and the machinery capable of slowing it are moving at the same time, and which one bites first shapes what ships next. Note: the Pro pause is under consideration only and has not been decided.
What to watch
Whether OpenAI actually pauses new Pro sign-ups, and on what terms. And what the Safety and Security Committee, now including Christiano, takes up as its first substantive item.
