Nvidia’s push around open weights in AI picked up speed after OpenAI signed its letter of support, taking the number of backers from 25 to 50 in a short span, according to Forbes. The report centers on a public message from Nvidia CEO Jensen Huang, who posted about the effort on X on July 24.
The rapid increase in signers signals growing interest in the open weights debate, a topic that has become increasingly important across the AI industry. In simple terms, the issue touches on how broadly AI model weights should be made available and how that affects development, access and competition.
The story also points to who did not join. While OpenAI added its name, Amazon and Anthropic were not part of the letter, creating a clear contrast between companies supporting the initiative and major AI players choosing to stay out, at least for now.
For technology and business leaders, that split matters because industry support around open weights can shape AI strategy, partnerships and product planning. With Nvidia publicly championing the effort and the supporter list expanding quickly, the conversation around open versus closed AI approaches is becoming harder for companies to ignore.
