Garry Tan announced YC's new RFS "We want to defend America," supporting defense-related startups. He also opposed efforts to ban Chinese open-source AI models, citing support from nearly 200 Silicon Valley companies urging the White House not to cut access. — via 1 2 3
Naval revealed that Anthropic web-scraped his data from GitHub, Twitter, Reddit, Discord, and Facebook to train the Fable model, and warned that the "IP theft" framework will backfire on Anthropic as Hollywood and publishing now have similar legal grounds. — via 1 2
Rand Fishkin cited Similarweb's 2026 AI Landscape report showing traditional search growth outpacing AI, and e-commerce/social media websites growing at the same rate as AI, challenging the "AI-everything" narrative. — via 1
Levelsio speculated that the US may soon permanently ban the use of Chinese AI models, referencing Moonshot AI's distillation of Anthropic's model as a harbinger. — via 1
Aravind Srinivas criticized AI regulation, arguing that concerns about OpenAI violating Hugging Face could lead to regulatory capture, and called for formal criminal investigation first. — via 1

Tesla's Q2 shareholder update: Cybercab production begins in Texas, Semi expected to volume produce in Nevada, FSD subscription rate at all-time high with over half of new North American deliveries subscribing, Robotaxi operating in 7 US metro areas with expansion ongoing. FSD safety data: 12.1B+ miles driven, major crash rate 7x lower than US average, Robotaxi 380k miles with no major accidents. — via 1 2 3
