Jensen Huang's First Post Ignites AI Route Debate, Tech Giants Co-sign for Open Weights

NVIDIA CEO Jensen Huang officially opened his X account, using his first post to share an NVIDIA-signed open letter titled "Open Weights and American AI Leadership," clearly expressing support for open-weight models. This move triggered widespread follow-up and discussion among tech giants and the AI industry, fully publicizing the divergence in AI model routes among major companies.

Confirmed

In his first post, Huang emphasized that AI will reshape all industries, and that open models can enhance safety and cybersecurity, accelerate the diffusion of innovation, and empower technological sovereignty. He argued that the knowledge needed to make AI truly useful is dispersed, so AI must also be distributed; the world needs both closed and open-source frontier models. Elon Musk subsequently expressed his complete support for Huang's stance.

This open letter was jointly released by a coalition of companies, arguing that American AI leadership depends on open-weight models and urging policymakers not to restrict them. Microsoft CEO Satya Nadella and Google CEO Sundar Pichai both publicly expressed their support: Pichai emphasized that open weights are crucial for a healthy AI ecosystem, citing the Gemma model as proof of Google's long-term commitment to open source; Nadella pointed out that open weights do not equal fully open source. OpenAI also confirmed signing the letter, with Sam Altman stating he hopes the US wins on both open and closed routes, and believes facing overseas competition requires an "offensive" approach relying on compute and talent rather than suppressing open source. Currently, over 50 AI companies and infrastructure players, including Ollama, have co-signed.

Unconfirmed

Some posts (like @heyshrutimishra) mentioned the letter is dated July 2026, which requires further verification. Additionally, there were rumors that OpenAI refused to sign (as relayed by @ns123abc), but subsequent lists showed they joined, leaving the exact signing process and timeline somewhat controversial.

Why it matters

This is a rare personal public statement from Huang, marking a clear alignment of the leading compute hardware giant regarding AI regulatory routes. The debate between open and closed routes directly relates to national technological sovereignty and industrial ecosystem trajectories. With the collective alliance of Google, Microsoft, OpenAI, and others, the camp supporting open weights has grown massive, pushing the closed-source adherent Anthropic into the opposite corner (prompting sharp criticisms like "Anthropic must lose" from @teortaxesTex). This will undoubtedly profoundly impact future AI policymaking and the industry landscape.
