Tech giants push to keep open-weight AI rules light as Chinese rivals rise
A coalition of about 25 tech firms including Nvidia, Microsoft, Meta and Palantir urges U.S. policymakers not to rush restrictions on open-weight AI models, arguing that open access promotes competition, safety, and broad innovation. Chinese open-weight models like Moonshot AI’s Kimi K3 are gaining traction, intensifying the policy debate, while OpenAI and Anthropic did not sign the letter as they pursue large IPOs. The group calls for targeted legal frameworks rather than sweeping bans and emphasizes that openness helps diffuse AI benefits across the economy.
