The text, an excerpt from a Google DeepMind video transcript, introduces SIMA 2, an advanced AI agent designed for interactive 3D virtual environments. This agent is highlighted as a significant improvement over previous models because it can handle complex, multi-step tasks and reason about its surroundings using multimodal prompts. SIMA 2 possesses the ability to learn and improve autonomously by playing within these worlds, gaining new skills without human intervention. Crucially, the agent can transfer its learned knowledge from one virtual world to entirely new, unseen environments. Ultimately, the development of SIMA 2 is viewed not just as progress in virtual training but as a step toward creating versatile AI capable of assisting with real-world tasks.
