research onlyModel evaluation bench for the Kuku Yalanji training run. This page tracks the full v8-v20 diagnostic ladder, saved outputs, downloads, and resource profiles from each RunPod run.
Where the model is after 48 hours
The training pipeline works. v20 trained the full candidate corpus and fixed the length-compression failure, but it also proved that scale alone is not enough. The hard problem is now product routing, mixture control, and faithful generalization, not GPU plumbing.
Exact known text
lookup-first
Bible references, DB usage examples, and elder-shared sentence pairs should come from the approved source table, not generation.
Bible draft
v12.0
Best current Bible-draft fallback by heldout Bible chrF; still not faithful canonical reproduction.
Usage draft
v10.0
Best current heldout DB/general usage signal. Newer balanced runs have not beaten it.
Latest research
v20.0
Full-candidate-corpus diagnostic; length compression is fixed, but faithful generalization is still unresolved.

Release verdict
Retain the exact published v21.2 weights and guarded decoder as reproducible research artifacts, but do not load them for public CPU inference while natural elder-register transfer remains unsolved. The homepage uses separately labelled dictionary-context prompting until a stronger RunPod candidate clears the frozen linguistic and safety gates and receives appropriate speaker review.
- The merged model SHA-256 is exactly the published v21.2 identity; this is a decoding-policy release, not a renamed checkpoint.
- The decoder was selected on the v22 development set and locked before v22 test/control inference and before any v21.2 transfer inference.
- A first transfer attempt reconstructed non-identical float32 bytes and was rejected before evaluation; only the exact published v21.2 merged model was scored.
- Guarded versus greedy tagged synthetic corpus chrF changed by +1.8723 while repeated-segment rows fell from 37 to 2; all seven frozen sets had zero empty outputs.
- Exact match fell on some sets and Bible chrF changed slightly downward; these outcomes are reported in the experiment book rather than hidden.
- A post-training 297-prompt canonical-headword probe scored this release at 48/297 normalized accepted-reference exact matches (16.16%); the result was 46/192 for target forms seen as training tokens and 2/105 for unseen targets.
- Under the same fixed decoder, step 4,155 exceeded step 3,120 by 1.68 exact-match percentage points on the lexicon probe (paired 95% interval +0.34 to +3.37), while the 43-row elder difference remained inconclusive and every checkpoint was 0/43 exact.
- An exact NVIDIA A40 reproduction evaluated all 340 frozen rows for steps 2,770, 3,120, and 4,155. All 1,020 GPU predictions matched the frozen local baselines, and a second A40 run reproduced all 1,020 predictions exactly.
- The portable evaluator fail-closes on input, model-file, runtime, decoder, determinism, GPU-use, empty-output, baseline-parity, and output-checksum violations. Its compressed kit is 100,526 bytes and excludes model weights.
- A first complete A40 attempt was rejected when a post-seal log append invalidated its checksum inventory. The failed attempt and repair evidence remain in the private research archive; only the clean from-scratch rerun is published.
- On 2026-07-14 the Kuku Yalanji and Mi'gmaq CPU inference workers were stopped and disabled, their web-service dependencies were removed, and custom-model endpoints were cleared. This release remains downloadable and reproducible but is not currently loaded for live translation.
- Automatic metrics are regression evidence, not community validation. Lookup-first routing and explicit research-draft labelling remain required.

Version ladder
Every material training branch from the last two days is listed here so the model line is auditable. chrF is useful for comparison, but exact approved known resources stay lookup-first.
| Version | Role | Bible ref | Usage | Elder rows | Decision | Links |
|---|---|---|---|---|---|---|
| v24.3-joint-lexeme-dose29-s3598-20260715 v24.3-joint-lexeme-dose29-s3598-20260715 | Current runtime-verified Kuku Yalanji research candidate for closed-set lexical reconstruction and separately labelled sentence drafts runtime verified research candidate | n/a | 53.17 | 0/43 | The governed training-overlapping lexical gate and every frozen development retention check passed. ADVANCE authorizes further research, not unrestricted deployment: the model remains 0/43 exact on the elder diagnostic and lacks speaker-diverse human evaluation. | |
| v21.2-claude-balanced-replay-guarded-20260714 v21.2-claude-balanced-replay-guarded-20260714 | Current Kuku Yalanji research model of record: frozen v21.2 weights with validated guarded decoding; CPU inference is intentionally unloaded research only | 43.84 | 47.96 | 0/43 | Retain the exact published v21.2 weights and guarded decoder as reproducible research artifacts, but do not load them for public CPU inference while natural elder-register transfer remains unsolved. The homepage uses separately labelled dictionary-context prompting until a stronger RunPod candidate clears the frozen linguistic and safety gates and receives appropriate speaker review. | |
| v23.0-attested-narrative-adaptation-failed v23.0-attested-narrative-adaptation-failed | Rejected three-seed attested-narrative adaptation retained as compact negative evidence negative result | n/a | n/a | n/a | Do not promote. Seed 73 improved the held-out Text 3 corpus chrF++ point estimate by 0.6414, below the preregistered +1.0 floor; its paired interval crossed zero, untagged synthetic repetition worsened, and isolated lexical reconstruction fell to 46/297. | |
| v22.0-step-matched-replay-3120-failed v22.0-step-matched-replay-3120-failed | Rejected one-variable replay-exposure experiment retained as negative evidence negative result | n/a | n/a | n/a | Do not promote. Step 3,120 failed the frozen greedy checkpoint gate because tagged synthetic repeated-segment rows were 37 against a maximum of 25, and paired comparison showed lower tagged synthetic, untagged synthetic, and dictionary-usage agreement than the final v21.2 step 4,155 checkpoint. | |
| v21.2-claude-balanced-replay-v2-candidate v21.2-claude-balanced-replay-v2-candidate | Historical v21.2 weights release; superseded for serving by the guarded-policy release without changing weights research only | 43.91 | 47.14 | 0/43 | Balanced replay preserves synthetic performance while materially recovering dictionary-usage and Bible retention relative to v21.1. Natural elder-register transfer remains unsolved, and synthetic morpheme loops remain a hard safety failure; serve only as a clearly labelled research draft pending speaker review. | |

Preserve as a research artifact; keep retrieval-first routing and require balanced replay plus speaker review before promotion. | |

| v11.0-byt5-bible-control-32row v11.0-byt5-bible-control-32row | Byte-model control negative result | 5.71 | n/a | n/a | Failed the tiny overfit/control path; NLLB/LoRA remains the proven memorizing path for now. | |
