What if a single token triggers LLM's mathematical reasoning failure?

Excited to share our new paper, Cliff Tokens! 🎉 We identify the exact token where a reasoning trace loses its potential to reach the correct answer.

We asked 3 key questions. Thread👇

Thanks to my amazing co-authors (@yukyunglee_ and Prof. Pilsung Kang).

Read the full paper to see how single-token dynamics shape LLM reasoning!
