A human brain consumes less power than a light bulb, while artificial intelligence systems guzzle electricity to do the same tasks.

Now, scientists have created a highly efficient AI model that hints at how living brains are able to do so much with so little, a team reports in the journal Nature.

The model, which mimics a part of the brain’s visual system, started out using 60 million variables. But the team was able to compress it into a version that performed nearly as well using just 10,000 variables.
