The Closed-Model CEO Warning About Closed Models
In an August 23, 2026 podcast interview, Altman named two things he considers the top risks in AI: models becoming too powerful for humans to guarantee control over, and power getting concentrated in "one company or model or person" [4].
The claim lands awkwardly for OpenAI itself. Reporting on the interview noted that OpenAI has released only two open-weight models, gpt-oss-120b and gpt-oss-20b, while Anthropic has released none [1]- though neither company has open-sourced the frontier, revenue-generating systems that actually matter most. Coverage published the week before the interview went further, noting that OpenAI and Anthropic were both reported to be sitting near $1 trillion valuations with confidential 2026 IPO filings underway, and that a 32+ company open letter on AI - signed by Microsoft, Meta, Nvidia, and Google - saw Anthropic decline to sign, while OpenAI's own commercial incentive to keep its best models proprietary went unaddressed in Altman's own framing [2]. The recurring observation across coverage: a company whose core product is concentrated control over a scarce capability is the one publicly warning the world about the dangers of concentrated control.
