America's top three closed-source AI giants OpenAI, Anthropic, and Google have yet to sign a joint open letter from Hwang In-hoon

In comparison, Hwang In-hoon posted his first tweet on the X (original Twitter) platform with a joint open letter entitled “Open Weights and America's Leadership in AI”. However, up to now, OpenAI, Anthropic, and Google, the three major closed source cutting-edge AI laboratories in the US, have not signed the joint open letter. More than 20 companies that have co-signed include Nvidia, Meta, Microsoft, Palantir, CrowdStrike, IBM, ServiceNow, and Hugging Face, Mistral AI, a16z, Y Combinator, Perplexity, etc.

According to reports, the open letter argues that “AI distillation (AI distillation)” technology should not be restricted, and that the standard for measuring America's AI leadership is not the strength of a single cutting-edge model, but whether it can build a stable and open ecosystem that penetrates all industries. The open weighting model is the cornerstone of this ecosystem.
