Google DeepMind Unveils SIMA 2: A General-Purpose AI Agent Powered by Gemini, Achieving Near-Human Performance in Complex 3D Virtual Worlds with Enhanced Reasoning and Self-Improvement

Google DeepMind has launched SIMA 2, an upgraded general-purpose AI agent designed to navigate and perform tasks in complex 3D game environments. Building on its predecessor, SIMA 1 (released in 2024), SIMA 2 integrates the Gemini 2.5 Flash Lite model as its core reasoning engine, enabling it to better understand goals, interpret plans, and continuously learn through self-improvement. While SIMA 1 achieved a 31% task completion rate with over 600 language instructions, SIMA 2 significantly boosts this to 62%, nearing the 71% completion rate of human players. SIMA 2 maintains the same interface but transforms from a mere instruction executor into an interactive game partner, capable of explaining its intentions and answering questions about its goals. It also expands its instruction channels to include voice, graphics, and emojis, demonstrating advanced reasoning by interpreting abstract requests. Furthermore, SIMA 2 features a self-improvement mechanism where it learns from its own experience in new games, with the Gemini model generating and scoring new tasks, leading to success in previously failed scenarios without additional human demonstrations. DeepMind also showcased SIMA 2's integration with Genie 3, allowing it to generate interactive 3D environments from a single image or text prompt, marking a significant step towards advanced real-world robotics.
