NVIDIA, Microsoft Push US to Back Open-Weight AI Models

A coalition of technology companies, led by NVIDIA and Microsoft, is making a public case to the US government that open-weight AI models—systems whose weights (learned parameters) are disclosed publicly—deserve government support. The coalition argues that backing such models is essential for strengthening US competitiveness in artificial intelligence and for expanding AI adoption more broadly. Open-weight models differ from proprietary AI systems in that researchers, developers, and smaller companies can access, study, and build upon them without licensing restrictions. By making this argument to federal policymakers, the coalition appears to be positioning open models as a strategic asset that complements rather than competes with proprietary systems, potentially widening the pool of organizations capable of deploying AI technology. The article does not provide details on specific policy proposals the coalition has submitted, the identities of all members beyond NVIDIA and Microsoft, or the timeline for any policy response.

The article reports a coordinated push by major technology firms to influence US AI policy in favor of open models. NVIDIA and Microsoft's leadership of this effort signals that established tech giants see open-weight systems not as a threat to their proprietary offerings, but as complementary infrastructure that can grow the overall AI market and reduce friction for downstream developers and enterprises. The framing—that open models strengthen competitiveness and expand adoption—suggests the coalition views the policy debate as one of ecosystem health rather than pure market share. The reference to Kimi K3 in the headline hints at competitive pressure from non-US AI models, though the body does not elaborate on this connection.
