Former OpenAI Scientist Ilya Sutskever Details Attempt to Oust Sam Altman and Merge with Anthropic

Nov 4, 2025
Former OpenAI chief scientist Ilya Sutskever revealed in a court deposition that he and other board members planned to remove CEO Sam Altman in 2023 and discussed merging with rival Anthropic before Altman was reinstated days later.

Former OpenAI chief scientist Ilya Sutskever described in a recent deposition filed in federal court how he and other members of the company’s board attempted to remove CEO Sam Altman in November 2023 and briefly explored a merger with rival Anthropic.

Sutskever said he spent over a year considering Altman’s removal and presented a 52-page memo to OpenAI’s independent board members outlining concerns about Altman’s leadership. The board ultimately voted to dismiss Altman on November 17, 2023. Within days, however, hundreds of employees signed a petition demanding his return, and Altman was reinstated as CEO on November 21.

During Altman’s brief absence, Sutskever stated that OpenAI board members held talks with Anthropic’s leadership, including CEO Dario Amodei and president Daniela Amodei, about a potential merger that would have placed Anthropic in control of OpenAI. According to Sutskever, most board members were supportive of the idea, though he personally opposed it. The discussions ended quickly after practical challenges were raised.

The deposition was part of Elon Musk’s ongoing lawsuit against Altman and OpenAI, which accuses the company of abandoning its original nonprofit mission. Sutskever is expected to sit for a second deposition to discuss additional internal communications related to Altman’s 2023 ouster.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
