Reflection AI
Ioannis Antonoglou is the co-founder and Chief Technology Officer of Reflection, building frontier open intelligence accessible to all. As a founding engineer at Google DeepMind, he was instrumental in creating some of the most revolutionary AI systems in history, serving as a core architect behind AlphaGo (the first AI to defeat a world champion Go player), AlphaZero (which mastered multiple games through pure self-play), and MuZero (which learned to plan in unknown environments). He also led RLHF training for Google's flagship LLM, Gemini. These breakthroughs fundamentally redefined the boundaries of artificial intelligence and demonstrated how AI could transcend human intuition through computational creativity.
