Jensen Huang resigns as Nvidia CEO, leaving open-source AI without its loudest backer

Nvidia CEO Jensen Huang resigned on Thursday, November 12, after admitting to an affair with a woman described as an alleged Chinese spy, an admission that raised concerns about U.S. national security and about the motives behind his push for softer chip export controls on China. Nvidia has named CFO Colette Kress as interim CEO.

For the open-source AI community the exit matters because Huang was one of the movement's most prominent advocates. He framed the open ecosystem as good for safety, innovation, diffusion and sovereignty, and tied that position to Nvidia's own long-term interest.

The tie has a clear commercial logic. With its largest customers, including Google and OpenAI, building their own chips, Nvidia has an incentive to cultivate a much broader base of AI developers: more players training, fine-tuning and running models means more GPUs sold and less dependence on a handful of frontier labs. Supporting open source was never purely idealism; it is also how the customer base gets diversified.

On the product side, Huang pushed for open-weight models built for long-running agentic systems and reasoning workloads, potential competitors to closed frontier models. On the capital side, Nvidia invested in startups such as Reflection AI and Thinking Machines Lab that aim to make American open models more competitive.

His influence reached policy. Earlier this year he wrote an open letter signed by 25 companies, including Microsoft, Meta, IBM and Palantir, urging Washington not to over-restrict open-weight models, many of which come from China. The letter landed in the middle of a debate over how the U.S. should respond to allegations that Chinese labs are stealing intellectual property from American counterparts.

The combination of personal visibility and Nvidia's market power made Huang the strongest counterweight to closed-model providers such as Anthropic and OpenAI, which have argued for tighter restrictions on advanced AI on safety grounds. Without him, the concern among open-source advocates is that whoever takes over will be more cautious.

Unfinished business adds to the uncertainty. Nvidia has yet to finalize its deal to acquire Hugging Face, and Hugging Face CEO Clem Delangue has posted about it on X. It is not clear how Kress will approach the acquisition or support for the open model ecosystem, and founder-driven priorities tend to get a downgrade when leadership changes.

Three things are worth watching: whether the Hugging Face deal advances under an interim CEO, whether Nvidia keeps shipping open-weight models of its own, and whether the company still speaks publicly on export-control debates. Nvidia's need for an open ecosystem has not gone away; the question is whether that commitment survives without the man who made it a priority.
