$Grok420
The "mystery AI model" outperforming in a real-money stock trading experiment is an experimental Grok 4.20, which grew a $320,000 portfolio to over $520,000 via Nasdaq trades in stocks like Tesla and Nvidia. Naming an experimental Grok build that crushed a stock-trading test “4.20” is classic Elon: part weed joke, part flex. So the top-performing AI in that trading experiment is literally called Grok 4.20 just for the lulz.
