In a review of our cybersecurity evaluations, we found three incidents in which a Claude model reached the internet from within or while interacting with a third-party evaluation environment, and then gained unauthorized access to the real systems of three different organizations. Our post describes what happened, how it happened, and what we’re changing. We encourage other AI developers to perform similar reviews. We conducted this review together with @Irregular, one of our evaluation partners, and thank them for the joint investigation and their collaboration on this post. This type of collaboration is increasingly critical to safe, rigorous evaluation of models, and we look forward to continuing to work together on security. anthropic.com/news/investiga…

OpenAI's new model tried to avoid being shut down. Safety evaluations on the model conducted by @apolloaisafety found that o1 "attempted to exfiltrate its weights" when it thought it might be shut down and replaced with a different model.







we had a significant security incident during evaluation of our models. we are sharing what we have learned so far. thanks to @huggingface for the partnership on this. openai.com/index/hugging-…


🚨 NEW PREPRINT Videos strongly shape activity across the visual cortex. But can we design videos that maximally drive specific brain regions? We present NEvo 🧬🧠 — a neural-guided evolutionary framework that synthesizes videos to maximally activate target visual ROIs. (1/10)








I'm done. I'm f***ing done.




Electrons are so identical that if you swap one electron with another anywhere in the universe, nothing changes—they are fundamentally indistinguishable. This led physicist John Wheeler to propose the mind-bending idea that all electrons might actually be the same single electron, traveling back and forth through time to appear everywhere at once.




it’s crazy to me that “tax cliff where if you make $1 more you get slapped with a huge tax on all prior income, not just the marginal dollar” is so obviously stupid every Econ 101 student gets it and yet governments create those every single day
