BIG PERSONAL UPDATE. I've joined a16z as a partner investing in infra and AI. I'm also stepping down as CEO of Rosebud AI. I reflect in this article on my 8 years of building in generative AI. At @a16z I‘ll be focusing on the frontier model stack: the models, and the infra and dev tooling around them. I'm excited about rapid model progress, increasingly driven by AI itself, and about what AI is unlocking for math and the sciences. And I’ll always have a soft spot for AI creative tools, having built them for 8 years.
