OpenAI reportedly signed the Nvidia–Microsoft open-weights letter

In a reply to another user, Prateek Jain says OpenAI told him it signed the Nvidia–Microsoft open-source/open-weights AI model letter today.

He frames it as a striking reversal and teases Anthropic to follow suit, suggesting the letter may be becoming an important industry signal around open weights and model access.
