Alphabet DeepMind Invites Developers Into the Digital World Where its AI Learns to Explore

Even a fledgling AI needs a place to play.

Alphabet DeepMind, the company’s moonshot AI factory, is announcing today an open-source version of “Lab," its internal digital world where it teaches AIs how to navigate 3-D spaces. The software, available on GitHub this week, looks like a cartoonish video game—but it has been carefully built to give AI developers control over how their bots learn. It’s not just fun and games—the Lab is a virtual environment that attempts to teach AI strategy, planning, time management and motor control.

Videos released by DeepMind depict a human navigating through the Lab’s world as an AI would.

“The only known examples of general-purpose intelligence in the natural world arose from a combination of evolution, development and learning, grounded in physics and the sensory apparatus of animals,” DeepMind researchers write in a blog post. “There are compelling reasons to think that it may be fundamentally easier to develop intelligence in a 3-D world, observed from a first-person viewpoint, like DeepMind Lab.”

The AI’s “body” in the Lab is a floating orb, which can be moved by firing thrusters from any direction. Instead of having access to the direct code of the 3-D environment, the Lab only allows AI to observe pixels the way a human would—meaning it has to learn to see and differentiate objects. Out of the box, the AI can be tasked with navigating mazes, playing laser tag and trying not to fall off precarious cliffs. Developers will be able to easily create and share new levels, and DeepMind says it hopes a community will form around building levels that teach different skills.

DeepMind has traditionally operated under the assumption that video games could teach AI many of the skills necessary to operate in the real world, like navigating tight indoor spaces to complete a task. Until recently, however, these attempts have been undertaken in games like Atari or Doom—poor analogues for the physical world. The Alphabet company has been using the Lab in its own studies, but an open-source version is likely to elicit ideas from other AI researchers, speeding up their own research in return.
