OpenAI quietly signs letter from Nvidia, Microsoft, and Meta warning about dangers of 'premature restrictions' on open-weight AI models — as the White House accuses China of stealing from Anthropic
Models like this are essential for making AI "more accessible, adaptable, and widely available" the open letter says.It's co-signed by a slew of well-known tech and AI companies, including Meta, Microsoft, Perplexity, and IBM. It's no coincidence that the US government led by President Trump has recently tried to take a more prominent role in evaluating AI models and deciding when they should be released.It's also notable that Anthropic and Google are missing from the list of backers to this open letter. We don't have any official comment yet from these companies, so it's hard to judge the reasoning — Google regularly releases open AI models, after all — but it could be something to do with recent accusations aimed at Moonshot AI in China.
