OSP-Qwen3-1.7B
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 and asset list.
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
The full OSP grid has five training prices (2e-6,5e-6,1e-5,2e-5,4e-5) and seeds 0, 1, 2. Each run contains osp_best.pt, the validation-selected top-two-block reader and stopping head. Use a run directory as --source-run with the matching iclr_score_pool snapshot; the base model is loaded separately.
These are the corrected-label full-grid runs. Qwen OSP-1 uses the same lambda-1e-5 checkpoints; it is not an additional training run. Use the root Qwen runtime.
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.
