Airbnb CEO Brian Chesky: “We’re relying a lot on Alibaba’s Qwen model. It’s very good. It’s also fast and cheap... We use OpenAI’s latest models, but we typically don’t use them that much in production because there are faster and cheaper models.” The valley is built on Qwen?

In my recent trip, the waymo market in SF has converged to ~2-3x the wait time and ~2-3x the cost of uber because that's how much more people are willing to pay for Waymo.

Recurring frontier lab gossip: OpenAI has best post-training/rl and has pushed it super hard on weaker pretraining. Gemini has spectacular pretraining. Making a reasoning model was super easy for them & OpenAI folks were surprised Anthropic? Secretive i guess.

A sign Google is waking up is them dropping by far and away the biggest free plans across the industry. This time is for the Claude Code competitor. Super excited, next time can be them getting rid of "Gemini Advanced" or whatever it is. Free Gemini.
