The letter was signed by 25 firms, including Meta, Microsoft, IBM, Andreessen Horowitz and NVIDIA.

Summary

Moonshot AI Slumps

Moonshot AI’s July 16 release of Kimi K3 sparked a sharp fall in chip-maker stocks as investors feared open-weight competition.
OpenAI CEO Sam Altman praised the open-weight letter but did not sign it, leaving Anthropic and Google also absent.
Microsoft AI chief Mustafa Suleyman says the firm will replace Anthropic API spending by building its own frontier models, while Nvidia and Meta could profit most if open-weight models expand.

History

Historical Context

In November 2019 OpenAI released the full 1.5-billion-parameter GPT-2 model, which AI-Dungeon’s creator Nick Walton quickly adopted, relaunching the game in December 2019 and drawing over 100,000 users within a week. The model’s rapid popularity and the later 175-billion-parameter GPT-3 launch in 2020 spurred commercial investment and debates over open-weight AI, a backdrop for the 2026 coalition’s regulator appeal.
