Help us build interpretability methods for real-world model monitoring! 🔬 We’re announcing new White-Box Awards in the AIMO Interpretability Challenge: $1,000 per track for methods that look inside the model (activations, patching, ...) Deadline Nov 1 → aimo-interp.github.io

A month left in the AIMO #Interpretability Challenge @NeurIPSConf 🧠 📊 1k+ submissions predicting whether #LLMs reason robustly on Olympiad-level math problems. ⚠️ Remember: high eval acc ≠ high test score. ⏳ Still time until 1 Nov. 👉 aimo-interp.github.io/

Super cool work! Maybe these circuits could also help disentangle robust from spurious reasoning on olympiad-level math problems? The main phase of our @NeurIPSConf competition just started 😉 aimo-interp.github.io
New preprint! 🤖➕➗ Shared circuits predict whether LLMs generalize across formats in arithmetic reasoning w/ @sanapandey, @pengrui_han, @jacobandreas, and @ev_fedorenko If you can solve 2+5, you can solve "two plus five" without learning math again. LLMs are more brittle (1/5)

Amazing! We'd love insights from open LMs too! "Understand" is the hard part, and our @NeurIPSConf competition. Do the most capable LMs reason robustly on Olympiad-level math problems, or just fake it? 🚨Main phase is on, two months left. aimo-interp.github.io
We partnered with @AnthropicAI @OpenAI to host the world's first math hackathon. 40 hours, $2M compute - solve, understand, and present an open problem. Applications are live: mathathonchallenge.com
