Meet JAT, an open-source Transformer agent that plays games and moves robots
Researchers just open-sourced JAT, a multi-purpose Transformer agent built to reproduce and improve upon Gato. Running on a single network, it tackles 157 tasks across Atari games, navigation, and robotic control, matching 65.8% of expert performance while supporting basic text and vision tasks. Why it matters: It opens up generalist embodied AI research with fully public models and datasets.
