Ioannis Antonoglou helped build AlphaGo, AlphaZero, and MuZero at DeepMind. Now he’s CTO and co-founder of Reflection AI, betting that frontier models should be open weights, not a black box behind an API.

In Part 1, we talk about openness as an actual strategy: why open models can move faster, why “sovereignty” matters for enterprises and governments, and why safety might improve when the ecosystem can stress-test the system instead of guessing.

We also get into the uncomfortable part: capable open agents can misbehave in public, fast (OpenClaw is the recent reminder). Is that a reason to close everything up, or a reason to make the risks visible and fixable?

Topics covered:

– Why a former DeepMind builder chose open weights

– Open models as a commercial engine (and what investors bought)

– Openness, safety, and “more eyes on the system”

– Concentration of AI power in closed labs

– Who open frontier models are really for (research, enterprises, governments)
