Stopped Python/math distillation sweep
Private archive of Qwen3-8B generated problems, code and explanations. Producer tar files preserve all accepted chunk JSONL.gz files (text, ids, qwen_ids), raw audits, progress and generation provenance, including uneven producer tails. Syntax checked; semantic correctness unverified. Token totals use the original frozen tokenizer, not Qwen.
checkpoints-and-metadata.tar preserves latest resumable checkpoints, metrics, validation and generations for the 27M, 48M and old 215.9M pilot. Other historical weight snapshots remain on the original Modal volume. The active 215.9M phased run is excluded. File SHA256 hashes and immutable upload revisions are in index.json. No source data was deleted.
