💬 Notable Quotes

"The new status symbol is making a model so powerful you can't release it."

— Dan Shipper
"Agents could do about 20 steps by the end of last year. GLM 5.1 can do 1700 right now. Autonomous work time may be the most important curve after scaling laws."

— Z.ai leader Lou
"Our military needs full access to Anthropics models if its technology is integrated into our sensitive systems. Military authority and operational control belong to the Commander-in-Chief and Department of War, not a tech company."

— Acting Attorney General Todd Blanche
