Political violence is bad. It usually begets more political violence. Celebrating political violence is bad. It usually encourages more political violence, against various targets. Campus shootings are bad. They make everyone on campus less safe. It's bad that what I wrote here is controversial.

Applications for Anthropic AI Safety Fellows are due Aug 17! US: job-boards.greenhouse.io/anthropic/jo... UK: job-boards.greenhouse.io/anthropic/jo... CA: job-boards.greenhouse.io/anthropic/jo... It's a great opportunity to get mentorship and funding to work on safety for ~2 months.

I've been talking about interference weights as a challenge for mechanistic interpretability for a while. A short note discussing them - transformer-circuits.pub/2025/interfe...

A number of people have asked me why we titled our recent paper "On the Biology of a Large Language Model". Why call it "biology"?

The elegance of ML is the elegance of biology, not the elegance of math or physics. Simple gradient descent creates mind-boggling structure and behavior, just as evolution creates the awe inspiring complexity of nature. x.com/banburismus_...

The Anthropic Interpretability Team is planning a virtual Q&A to answer Qs about how we plan to make models safer, the role of the team at Anthropic, where we’re headed, and what it’s like to work here! Please let us know if you’d be interested docs.google.com/forms/d/e/1F...
