The Anthropic Fellows has been one of the most impactful safety efforts I've had the luck of being involved with. And it needs help to scale! If you or someone you know has the required skills, I'd encourage you to apply.

Really neat finding. The ability of neural networks to pack so much in so little space may explain why they fall for adversarial attacks.

The "Circuit Analysis Research Landscape" for August 2025 is out and is an interesting read on "the landscape of interpretability methods" and model biology Qwen3 4B is also out on Circuit Tracer
Researchers from Goodfire, Google DeepMind, Decode, Eleuther, and Anthropic wrote a post about tracing circuits in language models! We cover how to train replacement models and compute graphs of model internals, and even filmed a 2-hour walkthrough of interpreting some examples!

New research with coauthors at @Anthropic, @GoogleDeepMind, @AiEleuther, and @decode_research! We expand on and open-source Anthropic’s foundational circuit-tracing work. Brief highlights in thread: (1/7)
In which the gang (@RunjinChen, @andyarditi, @Jack_W_Lindsey ): - identifies vectors for bad personas (evil, sycophancy, hallucinations, etc) - shows that if you inject the bad vectors in training, the model learns to not do the bad thing!! aka vaccines but for LLMs
