OC25
Catalysis model simulating explicit-solvent and catalyst systems for electrochemistry and energy applications.
What OC25 is
OC25 (Open Catalyst 2025) is a catalysis model developed by Facebook for research across chemistry, materials science, and energy. It serves as the successor to the earlier OC22 model.
The model is designed to simulate explicit-solvent and catalyst systems, supporting computational workflows in electrochemistry and energy conversion.

Run it here
We list this model but cannot run it yet: gated on the Hub — never run past a gate the user did not accept.
Everything on this page still applies. Running it needs a loader for this repository, not a bigger machine.
Strengths and limits
Good at
- Models explicit-solvent environments alongside catalyst systems.
- Acts as the successor to OC22 for electrochemistry and energy applications.
