OpenAI's head of enterprise sales, Barret Zoph, just announced his exit via an internal Slack message after only five months on the job. Zoph had rejoined OpenAI in January after leaving Mira Murati's startup Thinking Machines Lab, where he was co-founder and CTO. It marks his second high-profile departure in under a year.
Former OpenAI CTO Mira Murati just testified under oath that CEO Sam Altman lied to her to bypass safety protocols. In a video deposition shown during the Musk v. Altman trial, Murati said Altman falsely claimed legal cleared a new GPT model to skip the deployment safety board. Murati checked with general counsel Jason Kwon, caught the discrepancy, and forced the safety review anyway.
NVIDIA just made a major investment in Thinking Machines Lab, the new frontier AI startup founded by Mira Murati. The multiyear deal plans to deploy at least one gigawatt of next-gen Vera Rubin AI systems targeted for early next year to power frontier model training and serving. The AI compute arms race is officially entering the gigawatt era.
Thinking Machines Lab co-founders Barret Zoph and Luke Metz just left Mira Murati's fledgling startup to rejoin OpenAI, alongside early staffer Sam Schoenholz. The sudden move comes amid allegations that Zoph shared confidential data with competitors, though OpenAI dismissed the concerns and put him in a leadership role. Losing key technical founders is a massive blow to Murati's $12B venture in the middle of a brutal talent war.
Thinking Machines Lab, founded by former OpenAI CTO Mira Murati, just unveiled Tinker, an automated tool designed to fine-tune frontier open-source models. Developers can use a few lines of code to run supervised fine-tuning or reinforcement learning on Meta's Llama and Alibaba's Qwen, bypassing messy GPU cluster management entirely. Access is open via application for free during beta.
Former OpenAI CTO Mira Murati just announced a massive $2B funding round led by a16z for her startup, Thinking Machines Lab, driving its valuation to $12B. The team is building collaborative multimodal AI and plans to ship its first product in the coming months, complete with a major open-source component for researchers.
Mira Murati just announced the launch of Thinking Machines Lab alongside a team of scientists, engineers, and builders. The new lab is tackling three areas: helping people adapt AI systems to their specific needs, developing stronger foundations for more capable models, and fostering an open-science culture so the broader community can understand and improve them.
