@geoffreyirving Sad to see you leave, Geoffrey. Thanks again for all you have done for AISI. Hope to see you in the Bay Area and excited to learn more about the new org!

🧵New Anthropic Fellows research: We studied mechanisms of "introspective awareness" in LLMs.

LLMs can sometimes detect steering vectors injected into their residual stream. But is this worthy of being called introspection, or attributable to some uninteresting confound?👇

Haha those doofuses at ai2027 predicted we'd have professional level hacking abilities and the top ai company would be at $26B in revenue in May 2026. It's April and we already have superhuman hacking and $30B in revenue, why would you take forecasters this bad seriously???

We found concerning dual-use capabilities, sabotage and self-replication tendencies, political censorship on Chinese-language queries, and potential agentic misuse risks. (1/N)
