LongWorld training inputs, weights and experiment evidence

This public repository preserves local training inputs, selected inference weights, and experiment evidence for LongWorld. It is a recovery archive, not a production-qualified dataset or a claim that every historical training run can be resumed.

Training inputs

backups/2026-09-30/external-derived-sft-inputs/ contains 33 converted external baseline input and metadata files: ACC SWE/SQL/search, LongTraceRL, LongMIT, LoongRL, and DocQA. The archive is 7,381,892,506 bytes and restores 19,317,361,532 source bytes. Its file manifest and source references are included. These external baseline inputs remain separate from qualified LongWorld workflow rows.

Selected model weights

training/swift_ext_longtrace/v0-20260825-235057/checkpoint-200/ contains the latest available partial Instruct LongTrace checkpoint: step 200 of 680 planned steps, two safetensors shards, and required configuration/tokenizer files. PARTIAL_WEIGHTS_MANIFEST.json records per-file hashes, tensor layout, the preserved recipe, and historical step-200 eval loss 0.0802188515663147. This log value is not a matched quality comparison or an inference validation result. Both full weight shards were downloaded anonymously and verified by SHA-256 after upload.

The three completed step-680 baselines are already preserved in their separate model repositories:

  • Base ACC, commit 2b4dae0e6c3cddeaf6dea4e07d9ec1b31a250ddb.
  • Base LongTrace, commit 734d5a13211cdcf7a524d283e2fc982592cb09d9.
  • Instruct ACC, commit ca665f6df393b31414b1ff2c286a3dcb8997bd9f.

Those step-680 exports are the last checkpoints. The logs identify earlier best checkpoints for Base LongTrace (step 200) and Instruct ACC (step 600); their weights remain local and are not added by this cleanup. Base ACC best and last are both step 680. These completed weights are not duplicated in this backup. There is no completed P64 256k full-SFT checkpoint; that run stopped after an OOM at step 1.

Experiment evidence and task state

  • evaluations/runs/: MRCR, GraphWalks, downstream and aligned evaluation results and per-example samples.
  • evaluations/legacy/: held-out P4 inputs.
  • worktree/reports/: taskbank intermediates, receipts, candidate JSONL, audit outputs and historical failure diagnoses, retaining their original scientific status.
  • training/logs/: recorded launch, OOM, training and evaluation logs.
  • documentation/archives/2026-09-30/: durable research notes and pipeline ledger.

Current workflow training products are in LongWorld-Real-Workflows. Source/taskbank synthesis inputs are in LongWorld-Synthesis-Workspace. The curriculum and worlds snapshots are in LongWorld-Worlds-State.

Retained local SFT inputs

backups/2026-09-30/retained-sft-inputs-v2/ preserves all unique local SFT inputs and alternative export formats from the former mixed archive. Optimizer, RNG, scheduler and trainer pickle members are omitted. Exact duplicate originals restore through the included aliases. The replacement was downloaded anonymously in full and every retained member identity was verified before the former archive path was removed. Current assets are recorded in backups/2026-09-30/RETAINED_BACKUP_INDEX.json.

Historical snapshot and exclusions

The frozen state-2026-09-15 tag and original SNAPSHOT_MANIFEST.json are preserved. That manifest describes the intended snapshot, including large model and continuation-state entries that the former private storage quota rejected; an entry in that historical manifest does not prove the object was uploaded. Historical small checkpoint metadata and some small state files predate the current backup.

The 2026-09-30 selected backup does not add optimizer, RNG, scheduler or trainer pickle files. Superseded weights and wholesale failed/superseded generated-release archives are omitted. .venv, downloaded model/package caches, evaluation caches, serve views, tokenized caches, Git objects, probe signing keys and credentials are excluded.

Source files retain their recorded provenance and applicable source-specific licenses (license: other). The code and reproducibility records are in Xnhyacinth/longworld; exact original Git/Hub identifiers remain in documentation/STATE_HANDOFF_20260915.md.
