CoT Hidden-State Trajectories Chain-of-thought traces and generation-time hidden-state activations from 11 open-weight language models, on Codeforces (competitive programming), Hendrycks MATH, and SATBench (Boolean satisfiability). This dataset accompanies the paper Reasoning Models Don't Just Think Longer, They Move Differently (arXiv:2605.15454). The paper asks whether reasoning-trained models follow different hidden-state paths than matched instruction-tuned baselines, after… See the full description on the dataset page: https://huggingface.co/datasets/gjoelbye/cot-hidden-state-trajectories
