You might remember Project Vend: an experiment where we (and our partners at @andonlabs) had Claude run a shop in our San Francisco office.
After a rough start, the business is doing better.

New research from Anthropic Fellows Program: Selective GradienT Masking (SGTM).
We study how to train models so that high-risk knowledge (e.g. about dangerous weapons) is isolated in a small, separate set of parameters that can be removed without broadly affecting the model.
