Willison's August 2 roundup lays out "Open Weights and American AI Leadership" (July 24, Microsoft-shepherded, now 235 signatory companies including NVIDIA, Amazon, Y Combinator, the Linux Foundation, and OpenAI after initially abstaining); Anthropic's separate July 27 rebutta...
This is a supply-chain fact, and most people are still treating it as a geopolitics argument. Sequoia published "America's Open-Model Paradox" on July 24 with the number that reframes the whole conversation: Qwen's share of open-model fine-tunes went from 1% in January 2024 to...
Anthropic remains the only leading frontier lab that hasn't signed the Open Secure AI Alliance letter backed by Meta, Nvidia, OpenAI, Google, Microsoft, and SpaceX. Amodei's counter is that Anthropic never sought a ban and would instead restrict advanced chips to authoritarian...
