# Silicon Valley sharply divided over Chinese open-weight AI models as national security concerns rise

> As Chinese labs keep releasing capable open-weight models, Silicon Valley cannot agree on whether that is a threat or a gift. Anthropic's Dario Amodei has warned that China could weaponize powerful models for military use or repression, an argument for keeping them out of American systems. On the other side, Nvidia's Jensen Huang backs open models because they expand the pool of customers buying his chips, and OpenAI's Sam Altman says the US should aim to win in both open source and proprietary AI. The split is not just philosophical. Rest of World reports that 179 Silicon Valley startups have urged the Trump administration to preserve access to cheap Chinese models, which many of them build on to keep costs down. That puts national security hawks against a founder class that sees open weights as essential infrastructure. How Washington resolves the tension will shape whether American startups can keep using the cheapest tools available, or get walled off from them.
