Key points
- In recent months, we’ve made substantial progress on reducing the effectiveness of distillation attacks on Claude using new methods, as we outline in this blog.
- Distillation attacks are covert, industrial-scale campaigns to extract the capabilities of one model and replicate them in another, without the authorization of the original model’s developers.
- First, distillation enables companies to build models that approach the capability frontier, but which have, in practice, been released without proportionally robust safeguards.
- The US Center for Advancing Innovation and Standards for Super Intelligence (CAISSI) has since assessed GLM-5.3 to be the most cyber-capable open-weights model released to date.
