OpenAI’s former safety lead says it’s shipping ‘new capability and risk every Tuesday’
Former OpenAI safety lead David Robinson tells Ezra Klein that reasoning updates, new tools and coding agents now let OpenAI ship new AI risk every week.
Back in the day, a new generation started with another massive pretraining run. Only after that came post-training and safety testing. Robinson recalled that OpenAI even made a point of talking about the “month or months” of safety work that went into GPT-4 after the model itself was finished.
That anchor has loosened because the base model is now only one layer of what ships. “You’ve got the pretraining; that’s the baking of the underlying model,” Robinson explained. “But then, in addition to post-training, you have reasoning training — and those steps are easier to do quickly, so you can redo them.”
That means OpenAI doesn’t necessarily have to start over to get a more capable model. A better reasoning recipe can be layered onto the base model it already has. And the gaps between releases are getting remarkably short; GPT-6.1 Sol arrived at DevDay just a week after GPT-6 Sol.
“It’s not just a chat anymore,” Robinson said of the tools and affordances now wired into models, which can make a system more capable and change how it behaves, without any new training run beneath it. “All of those things are changing what the model can do and what the risks are, and we’re shipping new capability and risk every Tuesday,” he warned.
