Mira Murati Returns to the Spotlight with a Warning About AI Power and a Bet on Machines That Really Listen

After 18 months largely out of view, Mira Murati resurfaced on June 5 in San Francisco for a Bloomberg interview. The former OpenAI chief technology officer now leads Thinking Machines Lab, a startup she founded after leaving OpenAI in September 2024. She used the moment to preview a new generation of real-time conversational AI and to warn that too few people control the direction of artificial intelligence.

Thinking Machines Lab launched in February 2025 with a founding team drawn from OpenAI, Meta, and other labs, including John Schulman, Barret Zoph, and Lilian Weng. The company raised $2 billion, secured access to a full gigawatt of Nvidia’s next-generation Vera Rubin systems, and reached a $12 billion valuation after a round led by Andreessen Horowitz. But progress has been uneven. Its first product, Tinker, an API for fine-tuning open-source models, arrived in October 2025 but has not been a breakout hit. Several key researchers have since left, with Zoph, Metz, and Sam Schoenholz returning to OpenAI and five others joining Meta.

Murati addressed the departures directly, arguing that building a frontier lab from scratch compresses years of normal upheaval into a few intense months. She pushed back on the idea that rivalry alone drives her. “When I wake up in the morning, I am not thinking about how to kill the competitor,” she told Chang, drawing laughs.

The technology she highlighted aims to change how humans and machines interact. Thinking Machines calls them interaction models: systems that handle continuous streams of audio, video, and text, updating every 200 milliseconds. The first example, TML-Interaction-Small, returns responses in 0.40 seconds, matching natural conversation. Users can interrupt, and the system adjusts midstream, picking up on pauses, corrections, and tone.

Murati framed the work as a first step toward making AI feel more like a collaborator than a question-and-answer box. Her broader message: powerful systems require closer human partnership, not detachment. Neither dystopian nor utopian futures are locked in, she said. The choices made now will shape which path prevails.

Chang also asked about the chaotic November 2023 episode when OpenAI’s board fired Sam Altman and Murati became interim CEO for five days. Murati stood by her actions, saying she felt clear at each moment about protecting the mission and the team. But she admitted room for improvement, wishing she had pressed for more information and greater transparency.

When asked whether she still trusts Altman, Murati sidestepped, widening her critique to the concentration of consequential decisions in too few hands across the industry. “Good people still make bad calls,” she said. “Well-intentioned organizations can drift. Structural checks remain scarce.”

Her return comes as the sector wrestles with speed versus caution. Compute deals grow ever larger, talent raids intensify, and valuations balloon before revenue appears. Murati’s call for better governance does not propose slowing progress. It argues for mechanisms that prevent drift. Her product direction tries to embed collaboration directly into architecture, treating conversation as a live loop rather than a series of discrete prompts.

Whether that vision can hold against competitors racing to scale remains unproven. Thinking Machines has one commercial offering, and its research team has thinned at the top. Yet Murati sounded measured. Heads-down execution still matters, she suggested. But silence carries its own risks. The industry has moved fast without her. Now she aims to help set its next direction.
