Tech Giants Rally Washington Behind Open-Weight AI Models

On July 24, Nvidia CEO Jensen Huang posted his first message on X, sharing a joint industry letter that urges U.S. policymakers to avoid restrictive measures on open-weight artificial-intelligence (AI) models. The same day Satya Nadella, Microsoft’s chief executive, echoed the call on X.

Open-weight models are AI systems whose trained parameters can be downloaded, inspected, modified and run on any infrastructure. The approach differs from open-source software because the underlying code and training data remain proprietary. Chinese startups such as Moonshot AI have released open-weight large-language models, most notably Kimi K3 on July 16, which the company claims delivers frontier-level performance with 2.8 trillion parameters. The releases have sparked a policy debate in Washington, with the White House and Treasury officials alleging that some Chinese models may have been built using “distillation” of U.S. intellectual property.

• Historical reference: The 2025 U.S. AI Action Plan encouraged open-source and open-weight development as a strategic advantage for startups, researchers and government agencies.

• Industry supporters – Jensen Huang framed open models as essential to national security, stating that “the world needs both frontier closed models and frontier open models.”

• Opposing voices – OpenAI and Anthropic have publicly advocated tighter restrictions on Chinese open-weight models, warning that they could be exploited for malicious purposes. Treasury Secretary Scott Bessent warned of a potential crackdown on firms accused of cloning U.S. technology through distillation, while White House adviser Michael Kratsios alleged, without evidence, that Moonshot used large-scale distillation to copy Anthropic’s Fable model.

OpenAI and Anthropic argue that unrestricted open-weight models pose intellectual-property and security risks, especially when Chinese developers may employ undisclosed distillation techniques. U.S. officials have echoed these concerns, suggesting that “covert, industrial-scale distillation attacks” could merit sanctions or Entity List designations.
