I had a lot of fun vibe-coding a minimal AlphaZero, training it for Connect-4 on my laptop to a level that challenges my 7 y.o. (without any human data!) What used to take weeks now takes a couple of evenings. Try it here: hrzn.ch/alpha-zero-nan… Code: github.com/hrzn/alpha-zer…

I’ve always believed the No.1 application of AI should be to improve human health. That work started with AlphaFold, and now at @IsomorphicLabs with the mission to reimagine drug discovery and one day solve all disease! We are turbocharging that goal with $2.1B in new funding.
