Nvidia, Microsoft and Meta oppose AI model restrictions amid China competition
OpenAI and Anthropic exclude from joint letter as markets rally on trade summit news and chip export approvals

Nvidia, Microsoft and Meta have issued a joint warning against the implementation of "premature restrictions" on open-weight artificial intelligence models, citing intensifying competition from Chinese alternatives as a primary driver for their stance.
The letter, reported by CNBC, argues that such regulatory measures could hinder the competitiveness of leading American offerings in the global market. The signatories highlighted that Chinese open-weight models are gaining momentum, posing a significant challenge to US-based technology leaders.
Notably, major AI developers OpenAI and Anthropic did not sign the letter, marking a divergence in industry perspectives on how to navigate the evolving regulatory landscape for open-source AI technologies.
The corporate communication coincides with a high-profile diplomatic engagement in Beijing, where US President Donald Trump and Chinese President Xi Jinping have commenced a two-day summit. The agenda for the talks encompasses trade relations, artificial intelligence policy, and regional security issues including the Strait of Hormuz.
Market reactions to the broader geopolitical developments have been positive. US stock indices, including the Dow Jones Industrial Average, S&P 500 and Nasdaq Composite, posted gains during the summit period. Nvidia shares surged more than 2% following news that US authorities had approved the sale of H200 chips to Chinese firms.
Other prominent US technology executives, including Elon Musk and Tim Cook, are also attending the Beijing summit, underscoring the strategic importance of the US-China relationship in the technology sector.
The joint stance by Nvidia, Microsoft and Meta reflects a broader industry concern regarding the balance between regulation and innovation, particularly as Chinese capabilities in open-weight AI continue to advance.
