A study published in Nature highlights Dreamer, an AI developed by Google DeepMind, which successfully navigated the complexities of Minecraft without training. After playing for nine days in a constantly resetting world, Dreamer independently learned to collect diamonds, a task typically requiring 20-30 minutes for humans. This innovative AI system absorbed its environment and adapted, marking a significant advancement in the quest for general AI capabilities. Researchers emphasize the importance of Dreamer's ability to learn autonomously, distinguishing it from previous AI methods reliant on extensive human-generated training data.
"Dreamer marks a significant step towards general AI systems," Google DeepMind researcher Danijar Hafner told Nature. "Every time you play Minecraft, it's a new, randomly generated world."
Collecting a diamond in Minecraft is no easy feat: Users have to find trees, cut them down, build a crafting table, build a wooden pickaxe, and dig deep underground to find a diamond.
After nine days, Dreamer was able to learn enough about Minecraft to mine a diamond in less than 30 minutes, just as quickly as a human player.
Throughout the experiment, Dreamer was able to absorb its physical environment in Minecraft and improve at the game without receiving step-by-step instructions from a human on how to get better.
