Why Reflection AI Bets Their Business on Open Weights | Ioannis Antonoglou, co-founder and CTO

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) Subscribe for Part 2: how Reflection plans to compete with closed labs and what they’re building under the hood.
