[AI DAILY NEWS RUNDOWN]

Google released the world's top-ranked AI model on Wednesday, and almost nobody can use it. Hours later, Alphabet's AI spending more than doubled, free cash flow went negative and the stock fell about 10%. Plus: GitHub halves the token bill, and analysts followed Claude's coin flip.

In this episode:

Gemini 4 Carbon: first on the Artificial Analysis index (59 vs. 58 for Opus 5.5), cyber defenders only, a higher hallucination rate than Argon, and a price that doubles after launch.
The bill arrives: $51.4B in quarterly capex, negative free cash flow, Search up just 12%, and about $280B in market value gone after hours.
Token economics: GitHub's Copilot Fusion matches top coding agents with half the tokens; Amazon tells engineers to stop "tokenmaxxing"; ChatGPT Pro usage cut in half.
Human in the loop: analysts followed Claude's secretly coin-flipped advice 86% of the time.
Security and politics: Black October's Y2K lesson and the first AI election ad campaign.
Cert Corner: which model should run millions of simple support requests? Answer at the end.
