Microsoft, Nvidia, Meta and 22 other companies sign open letter, urging US government to support open-source weight AI models

Microsoft, Nvidia, Meta and 22 other US tech companies jointly signed an open letter, urging the US government to support open-weight AI models. The open letter points out that open-source models can lower the barrier to AI use, promote competition, avoid technological monopolies, and give users control over their technological autonomy. At the same time, an open ecosystem helps mobilize global researchers to identify vulnerabilities, and is an important path to achieving AI safety.
