All the analysts forever writing about OpenAI vs Anthropic vs Google are missing the real story that already happened. 80% of startups pitching Andreessen Horowitz are running on Chinese open-source models. Not OpenAI. Not Anthropic. Chinese models like DeepSeek that cost 214x

This is the craziest stat of the World Series: Trey Yesavage, the Blue Jays starting pitcher who makes $57K a year, started the game by striking out Shohei Ohtani, who makes $47M - that's 824x his salary.

A Pineapple Express and a parade of storms are going to slam Northern California over the next week, dropping huge amounts of precipitation and potentially causing significant flooding. Many forecast models drop over 20 inches of rain across the Northern Sierra. Stay tuned.
