Its weights are published, so you can run it on your own hardware or a cloud of your choice. Read the license before commercial use.
When was esmfold released?
Mar 15, 2024.
Catalog data from models.dev (MIT licensed), refreshed daily, last on Oct 15, 2026. The summary is written from these facts.
Building on esmfold?
I test your real tasks on it and the two closest alternatives, then ship the agent on whichever wins on cost and accuracy.
