Dreamer 4 Achieves Minecraft Milestone Through Revolutionary 'Imagination Training'
Google researchers have unveiled Dreamer 4, an AI agent that mastered diamond collection in Minecraft using purely offline data—a first in reinforcement learning. By training within an ultra-accurate neural world model that simulates complex physics and object interactions, the agent outperforms predecessors while using 100x less data than OpenAI's VPT. This breakthrough demonstrates the potential for real-world applications where physical trial-and-error is impractical, such as robotics.
