be Yann LeCun > spend years building JEPA at Meta > company focuses on LLaMA instead > his idea stays complicated and unused > robotics plans get dropped > decides to leave and start AMI Labs > builds a much simpler version from scratch > trains it on normal hardware in just a few hours > removes all the complicated tricks and keeps it simple Results: -uses 200x less data than similar systems -makes decisions 50x faster -runs on a single GPU instead of massive clusters -simple to train -understands movement, objects, and space -can tell when something is physically impossible -learns how the real world works without being explicitly taught. Media Earlier this year Yann LeCun left Meta because Mark Zuckerberg wouldn't bet the company on JEPA. Last week his group dropped the first JEPA that actually trains end-to-end from raw pixels. 15 million parameters. Single GPU. A few hours. The timing is not a coincidence. For four y…
