About Hassana Labs

Hassana Labs is an independent AI research lab. We use information theory and symmetry to work out when AI models will fail, from hallucinating language models to world models that break the laws of physics, and turn the maths into open-source tools.

Each piece of work starts with a failure you can see in today’s models. We look for the maths that predicts it, then test the fix in public, and say so when it doesn’t work.

Who writes this

Leon Chlon, PhD, founded Hassana Labs and is AI Research Lead at PhysicsX. He was previously a Visiting Fellow at the University of Oxford (Torr Vision Group), a postdoctoral fellow at Harvard Medical School and a research affiliate at MIT, and did his PhD in machine learning at the University of Cambridge (Pembroke College). He has worked on machine learning at Meta, Uber/Careem and McKinsey, and wrote a free textbook, Information Geometry for Generative Models. Hassana Labs is independent of PhysicsX.

Why “Hassana”?

The lab is named after its founder’s grandmother. She loved learning, taught him mathematics, and made everyone around her feel valued. The lab carries that on: talent is everywhere, but opportunity isn’t.
