  • Emergent tool use from multi-agent interaction

    We’ve observed agents discovering progressively more complex tool use while playing a simple game of hide-and-seek. Through training in our new simulated hide-and-seek environment, agents build a series of six distinct strategies and counterstrategies, some of which we did not know our environment supported. The self-supervised emergent complexity in this simple environment further suggests that m

  • MuseNet

    We’ve created MuseNet, a deep neural network that can generate 4-minute musical compositions with 10 different instruments, and can combine styles from country to Mozart to the Beatles. MuseNet was not explicitly programmed with our understanding of music, but instead discovered patterns of harmony, rhythm, and style by learning to predict the next token in hundreds of thousands of MIDI files. Mus

  • Learning dexterity

    Dactyl is a system for manipulating objects using a Shadow Dexterous Hand. We place an object such as a block or a prism in the palm of the hand and ask Dactyl to reposition it into a different orientation; for example, rotating the block to put a new face on top. The network observes only the coordinates of the fingertips and the images from three regular RGB cameras. Although the first humanoid

  • Glow: Better reversible generative models

    An interactive demo of our model to manipulate attributes of your face, and blend with other faces Manipulating attributes of images of researchers Prafulla Dhariwal and Durk Kingma. The model isn’t given attribute labels at training time, yet it learns a latent space where certain directions correspond to changes in attributes like beard density, age, hair color, and so on. Generative modeling is
