From DeepMind Paris to Llama 3: Michal Valko shares his three hard problems at Prague AI meetup

What started as a 1:1 coffee turned into a 70-person AI meetup in Prague. Speaker Michal Valko previously helped set up DeepMind's Paris lab and later worked on Llama 3 at Meta.

His three hard problems: creativity, confidence (a model knowing when to trust its own answers), and collective recursive self-improvement—agents working together to improve how the next generation learns. He picked the last one for his new company Isara Labs, calling it the easiest of the three. He's also experimenting with a counterintuitive question: if training only rewards small improvements, what happens to ideas that need a few bad steps before working—like touch-typing, where speed drops before it rises.
