BELT-OLMo-3-7B-Think

Code and reproduction guide · Read-only paper snapshot

Original trained artifacts for Same Beliefs, Different Policies: Learning Reusable Representations for Early Stopping in LLM Reasoning. Files retain their original bytes. CHECKPOINTS.json records the seed, training price where applicable, original source path, byte count and SHA256. Each run includes the original summary.json and available execution metadata. SHA256SUMS covers all supplied files except itself.

These are custom reader/head checkpoints used alongside the pinned base language model, loaded through the BELT repository's scorer. They are not standalone language models. No backbone weights, question manifests, full trajectory banks or fitted BELT stopping policies are bundled. See the code repository's recipes, asset inventory and known limitations.

Source attribution is in the repository's NOTICE. This artifact publication assigns no new project license; backbone and upstream terms continue to apply.

Contents and use

Three seeds (0, 1, 2), each with s1_best.pt, contain the four-target reader and readouts (q,v,r,stability = Now, End, Later, Same). Use a run directory as --source-run with iclr_score_pool; fit or obtain the separate stopping-policy parameters before policy evaluation.

This is the corrected-label layer-18 scalar-mix family used by the OLMo primary tables. Use scripts/source_variants/olmo_belt first on PYTHONPATH; it constructs the saved self-contained reader and does not need the Qwen template.

Each run also includes its original val_scored.jsonl. The historical scorer requires this file and copies it into the scored output for calibration; row counts, byte counts and hashes are recorded under validation_scores in CHECKPOINTS.json. These records are the saved validation scores, not newly generated data.
