Bethge Lab

We study continual self-improvement — agents that get better with use.

The Bethge Lab is an academic, non-profit research group at the Tübingen AI Center, led by Matthias Bethge.
We work in the open, closely with Open Athena, the non-profit bringing frontier AI capabilities to academia.
