An AI Was Trained To Play Minecraft With 70,000 Hours Of YouTube Videos

OpenAI, the artificial intelligence research organization founded by Elon Musk, has trained an AI to play Minecraft almost as well as humans. It only took about 70,000 hours of binging YouTube videos. A blog post detailing the feat reveals that researchers used a technique called "Video PreTraining (VPT)" to train a neural network on how to play Minecraft. This involved gathering 2,000 hours of sample dataset from actual humans playing Minecraft to include not just the raw video, but also exact keypresses and mouse movements. From there, the researchers trained an inverse dynamics model (IDM) to predict the future action being taken at each step in the videos.
