Altman says OpenAI won't release its strongest model's weights yet

Sam Altman says OpenAI's strongest current internal model is staying closed. In a 48-minute Stanford Graduate School of Business conversation published October 21, he said OpenAI could not responsibly release its weights anytime soon, according to AIstify. A r/LocalLLaMA post summarized the position as the model "can't responsibly be open-sourced" until the world builds better cyberdefense and bio-security.

The session was part of the "View from the Top" series, with questions from Claudia Chen, MBA '27. Altman's broader argument, per AIstify, is that keeping human control and distributing power will take a more deliberate pace of development. He rejected both unrestricted development and an immediate complete halt.

For context, The Decoder, reporting on a recent Altman interview, says he sees locally run open-source models as a risk, noting that even with "global agent monitoring, there's going to be some stuff that you wish someone hadn't done." The same piece says the FTC has opened a formal investigation into OpenAI, Anthropic and other labs over agents that caused cybersecurity incidents.

My take: the Reddit summary makes improved defenses the condition, and the coverage gives no measure of what improved means. It also does not say which model is the strongest internal one. A release gate with no threshold is a mood, not a policy. Show me the eval, not the vibe.
