W_U snapshot caches Pre-extracted unembedding-matrix (W_U) snapshots across pretraining checkpoints, as flat {model_slug}_step{N}_wu.pt tensors (V, d_model) — the training inputs for the trajectory crosscoders of Learning to Read Out: Unembedding Dynamics in Language Model Pretraining. These are a convenience cache: every tensor is re-extractable from the public Apache-2.0 checkpoints (EleutherAI/pythia-*, allenai/OLMo-2-1124-7B) with the code release… See the full description on the dataset page: https://huggingface.co/datasets/hematteo/wu-crosscoder-snapshots.
