- Meta, Nvidia, Microsoft, and a16z were among the largest U.S. tech companies that signed a joint letter on Friday defending open-source AI software.
- Jensen Huang, in his first-ever post on X, publicly argued that open models strengthen cybersecurity, adding a national-security dimension to the industry's defense of open-weight AI.
Why it matters: The coalition of major signatories gives the open-source AI lobby its highest-profile industry endorsement to date, and Huang's cybersecurity framing reframes the debate from one about developer access to one about national security — a sharper argument against regulators weighing restrictions on open-weight models.
