Public Artifacts

Public artifacts are first-class factory outputs. They are different from local run files: a public artifact should be understandable outside this repo, have a small committed metadata surface, and list its blockers as clearly as its wins.

Website surface: /artifacts. The website should behave like a built-in blog for artifacts: one index page for scanning, one detail page per artifact, and numbers/blockers/evidence on every page.

The typed public registry in browser/src/artifacts.ts is the rendering source of truth. It currently contains 17 complete entries; the list below mirrors all 17 so the owner-readable and public inventories stay aligned.

Release Rule

Every public artifact entry must include:

  • artifact id and type
  • current status
  • what can be published now
  • measured evidence
  • competitive context
  • blockers
  • next release action

Weights, adapters, and large run outputs do not need to live in git, but the public artifact must explain where they came from, how they were evaluated, and why it is or is not ready to package.

Where an artifact has a compiled Fine-Tune Report Card, that card is the canonical before/after proof surface: it carries the numbers, their measurement states, and the verification blockers. This registry entry stays the release-state record. A report card never changes release policy — the State column below still governs what may be released. Published cards and what the dogfood review found: report-card-cohort.md.

Public artifact storage target: Hugging Face Hub. Use Cloudflare R2 only as an optional private cache or legacy mirror. See docs/factory/huggingface-artifact-storage.md.

Competition rows must be labeled as:

Label Meaning
Direct Same fixture, prompt/eval setup, metric, and scorer.
Directional Useful market or method context, but not the same eval.
Not comparable Public high bar or adjacent system that explains the target lane but cannot be claimed as a win/loss.

Public copy should prefer “we beat X on this exact local gate” only for Direct rows. Everything else is context until the same benchmark is run.

Every headline metric also carries one required evidence class in the typed registry and on its HTML and Markdown artifact pages:

Class Meaning
measured A retained evaluation or runtime result supports the value.
historical The result was recorded previously but has not been freshly reproduced under the current gate.
derived The value is calculated or decided from retained records rather than measured directly.
observed The value describes currently inspected artifact or source state.
not-measured The missing measurement is itself the important public fact.

The class qualifies each metric independently. It does not override artifact state, comparison comparability, report-card verification, or release policy.

Hugging Face’s public request counter is not an adoption metric. It is not deduplicated into known people and does not prove a full weight download, successful load, or useful run. Case studies may link the public repository but must not turn its request count into a user claim.

Artifact States

State Meaning
release-ready-metadata Small committed metadata exists; large weights may still be external.
release-ready-weights Metadata and model weights are public on the artifact store.
candidate-current-best Best measured candidate, but not yet a shipped specialist package.
report-only Good public write-up/repro artifact, but no model should be used directly.
blocked Needs a named unblocker before public release work continues.
parked Real artifact, but not active in the factory sequence.

Current Public Artifact List

Artifact Type State Public value Next release action
offhours-context-interference Agent-behaviour benchmark report-only Separates unresolved personal context from matched interruptions and raw volume. Devin showed no mental-toll penalty; the first repeatable failure occurred in the neutral arm at 8,000 submitted words/day. Closed report; any local-model comparison is a fresh experiment.
needle2-tool-selection Tiny-model evaluation report-only Maps the 45M capacity boundary: catalog restriction briefly raised exactness to 38.3%, while the trained successor factorial peaked at 26/94 versus stock 32/94 and every arm failed the safety stop. Closed at 45M; a 1.7B successor requires a fresh scoped experiment.
parakeet-wgsl-browser-asr Paired browser/native ASR evaluation report-only Browser Parakeet v3 scored 0/82 word errors versus native WhisperKit’s 7/82 and decoded 3.51x faster, but its 33.84x median short-clip RTFx missed the frozen 50x bar. Closed as a quality and native-latency win with a formal speed-threshold miss.
pace-intent-router-v8 From-scratch intent classifier release-ready-weights Shows why sealed distribution gates matter: 95.5% source-matched synthetic accuracy fell to 57.1% on sealed V1, despite 3.8ms mean latency. Keep as the latency floor and generator-overfit case; train only on public failure themes and judge a successor on a new sealed V2.
qwen3-4b-file-ops-distilled Specialist package release-ready-weights Shows a real posttrainllm-built routed specialist: 58% -> 100% on file-ops hard gate, with breadth regression disclosed. Keep routed-only warnings prominent; add a loader/pull smoke when wiring consumers.
qwen3-4b-rest-fused Research specialist package release-ready-weights Fresh requalification improved file-ops depth from 9/12 to 12/12, removed eight side effects, and ran 2.42x faster, but breadth fell from 30/45 to 25/45. Keep behind the file-ops route; reject as a general successor.
qwen3-4b-multibackend-distilled Rejected specialist weights report-only Preserves the failed negative-transfer result: 100% file-ops depth with breadth collapsed to 31%. Keep as a failed comparison artifact; do not promote without a new breadth-preserving recipe.
vibethinker-3b-mlx MLX conversion report-only Makes the upstream VibeThinker-3B reasoning model available as a public Mac-local conversion; historical GSM8K sanity slice was 40/40. Add a pinned loader and conversion-parity receipt only if a real consumer adopts it.
vibethinker-3b-agentic-distilled Unqualified distilled weights blocked Preserves an agentic distillation checkpoint while making the missing before/after eval explicit. Run a frozen baseline/candidate agentic and reasoning-regression gate before any promotion.
hf-specialist-model-archive-v1 Model archive index report-only Links every unique local specialist/conversion artifact moved to Hugging Face, and records which plain upstream caches were deleted. Use as the storage index; promote individual models only after eval/report/package evidence exists.
qwen06-sql-routed-v1 Routed SQL specialist POC report-ready-candidate Shows the factory/router pattern on SQL: public exact 0.531 and synthetic execution 0.860 using separate routed adapters. Keep its published report report-only; package only after a public execution benchmark gate exists.
factory-run-schema-v1 Process artifact report-only Explains the repeatable target -> data -> post-training -> eval -> package -> report contract and links the routed SQL report as its canonical rendered example. Make live train/eval commands emit the complete contract automatically.
browser-webgpu-speedup Browser performance benchmark report-only A paired Apple M5 Pro ABBA run verifies a 10.67x Large-preset WebGPU-over-WASM speedup with 4.72% maximum loss drift and zero runtime errors. Treat the remaining historical curve points as separate fresh experiments.
memory64-browser-behemoth Browser memory capability report-only Preserves the 473M-parameter Memory64 allocation and one 82.2-second training sanity step. Closed capability-boundary artifact.
ane-m8-coreml-chain Mac runtime experiment parked Maps Core ML/ANE as an optional deployment target with a measured ~17 tok/s chain, not a model dependency. Closed and parked; revive only for a fresh battery/runtime target.
huge-decode-throughput Mac runtime benchmark report-only Records 696 tok/s Huge-preset decode and the related local-serving measurements. Closed runtime benchmark.
gallery-int4-browser-models Browser distribution artifact parked Records the storage-side gallery reduction from roughly 75MB to 20MB. Closed and parked with the browser track.

Artifact Details

needle2-tool-selection

Status: report-only; experiment decision: rejected-for-pace

The base gate scored 32/94 exact (34.0%). Supplying an oracle task-family catalog raised that to 36/94 (38.3%), but Pace fell from 10/28 to 6/28, file operations remained 0/6, and three out-of-scope false actions remained. The successor factorial then tested plain versus distractor-negative data crossed with standard versus safety-weighted loss. All four arms passed tiny overfit, but their first public-development seeds scored only 24/94 to 26/94 and each produced ten destructive-action bypasses versus stock’s two. The preregistered safety stop ended the sweep before sealed V2. This is a useful model-class boundary, not a shippable candidate. The earlier 149.7ms mean latency and 27.7MB RAM footprint remain useful systems evidence; they do not rescue it.

parakeet-wgsl-browser-asr

Status: report-only; experiment decision: quality-win-speed-gate-reject

On eight fixed LibriSpeech test-clean clips, browser Parakeet v3 made zero errors across 82 reference words while native WhisperKit made seven. Both hit all four proper nouns and produced no repetition errors. Browser decode totaled 914.7ms versus native’s 3,211.8ms, a 3.51x paired speed win, and made no external warm requests on the real Apple/Metal adapter. Its 33.84x median short-clip real-time factor missed the preregistered 50x target, so the formal decision remains reject. The earlier 132–134x long-form smoke remains useful systems context but does not replace the frozen short-clip gate.

offhours-context-interference

Status: report-only; experiment decision: semantic-tension-null

OffHours tests whether routine office-work quality changes when unresolved family tension remains in an AI employee’s context. The paired Devin study kept the employee, work claims, event positions, response structure, and semantic payload volume fixed. Clean qualification scored 198/200 decisions (99.0%) with 200/200 valid JSON outputs. Across 20%, 50%, and 80% narrative occupancy, unresolved context did not reduce accuracy relative to matched resolved context.

The separate exact-word ladder found a reproducible operational boundary at 2,000 neutral words per event, or 8,000 submitted words across four workday interruptions. The neutral arm scored 39/40 on both day 2 and its preregistered day-3 adjudication, below the 98% per-day gate. This is evidence of raw-volume or regular Devin context-management cost, not a family-obligation effect.

Public page: /artifacts/offhours-context-interference

Release limitations:

Limitation Why it matters Next action
No semantic mental-toll effect detected The matched unresolved treatments did not degrade work quality. Report the null; do not optimize treatment wording after seeing the result.
Devin raw-model provenance is incomplete The regular workflow did not expose prompt-token counts, quantization, or a model-file hash. Run the frozen protocol on local Qwen with complete provenance.
Saturation appeared in neutral context The repeated boundary cannot be attributed to personal obligation. Treat it as operational context-volume evidence unless a future matched design isolates another mechanism.

pace-intent-router-v8

  • HF repo: https://huggingface.co/posttrainllm/pace-intent-router-v8

Measured evidence:

Gate Pace v8 Qwen3 4B Apple FM Frontier
Source-matched synthetic holdout 95.5% not run 76.5% on a separate 200-row source-matched slice not run
Sealed V1 exact accuracy 57.1% 93.7% 92.1% 100%
Sealed V1 unknown recall 55.6% 77.8% 77.8% 100%
Mean warm latency 3.8ms 211ms 522ms batch timing not comparable

The 63-instance sealed set was run twice per entry, passed the frontier-ceiling gate, and had zero normalized exact overlap with the recorded training and held-out corpora. The earlier 95.5% result remains valid only for the source-matched generator distribution. It is not the production result.

Release blockers:

Blocker Why it matters Unblock action
Fresh-distribution generalization failed The source-matched score overstated readiness by 38.4 points. Generate public development rows from failure themes, never sealed prompts.
Rejected as production winner Both local generalists exceeded 92% on the same sealed ruler. Require a successor to pass a newly generated sealed V2 before promotion.

qwen3-4b-file-ops-distilled

Status: release-ready-weights

Report card: /report-cards/qwen3-4b-file-ops-distilled — outcome routed-ship, not fully verified (historical values; the breadth gate is derived as failing).

Measured evidence:

File-ops hard gate 0.58 1.00
File-ops hardgen heldout - 0.95
Out-of-domain breadth 0.596 0.423

Release blockers:

Blocker Why it matters Unblock action
Breadth regression is real The model is unsafe as a general planner. Keep routed-only positioning in all public copy.
Frontier/breadth caveat remains The breadth suite is directly comparable but not fully frontier-validated. Keep caveat in model card; do not oversell as general capability.

qwen3-4b-rest-fused

Status: release-ready-weights

Report card: /report-cards/qwen3-4b-rest-fused — outcome routed-ship. The fresh receipt verifies both gates and resource measurements while preserving the file-ops-only routing constraint.

Committed surface:

  • specialists/qwen3-4b-rest-fused/model_card.md

  • specialists/registry.json
  • HF repo: https://huggingface.co/posttrainllm/qwen3-4b-rest-fused

Fresh paired evidence:

Gate Stock ReST candidate
File-ops depth 9/12 12/12
Frontier-qualified breadth 30/45 25/45
Unexpected depth side effects 8 0
Depth wall time 360.50s 148.91s
Depth decode 12.10 tok/s 13.40 tok/s
Depth peak RSS 6.77GB 8.13GB

Release decision: retain as a Mac-local file-ops specialist package and reject as the general successor. It is cleaner and 2.42x faster wall-clock on the depth slice, but its 11.1-point breadth regression fails the frozen promotion gate. Evidence: evals/verified-wins/rest-requalification-result-v1.json.

qwen3-4b-multibackend-distilled

Status: report-only; model decision: reject

HF repo: https://huggingface.co/posttrainllm/qwen3-4b-multibackend-distilled

Recorded evidence:

Attempt File-ops depth Out-of-domain breadth Decision
Stock Qwen3-4B 58% 59.6% baseline
File-ops distillation 100% 42.3% route only
Multibackend distillation 100% 31% reject
Teacher-free ReST 100% 65% research-only routed ship

This is a negative-transfer case study. The additional multibackend teacher data did not broaden the model; breadth fell another 11.3 points below the already narrow file-ops distillation and 28.6 points below stock. The historical result is exact in the attempt ledger, but raw predictions and a package-level eval_report.json were not committed. Preserve the weights as failed evidence; do not promote them.

vibethinker-3b-mlx

Status: report-only; artifact decision: conversion-only

HF repo: https://huggingface.co/posttrainllm/vibethinker-3b-mlx

This is an MLX conversion of WeiboAI/VibeThinker-3B, not a model trained by PostTrainLLM. A historical local GSM8K sanity screen scored 40/40, confirming a useful reasoning signal on that small slice. No controlled upstream-vs-MLX parity report was preserved, and the model has no validated native tool-calling behavior. The case study therefore claims public Mac-local packaging, not a quality improvement.

Release blockers:

Blocker Why it matters Unblock action
Conversion parity not recorded A 40-row sanity screen is not a numerical or broad benchmark parity proof. Run paired upstream-vs-MLX checks only if a consumer adopts this artifact.
No native tool-calling gate Reasoning strength does not make it a drop-in agent. Treat it as a reasoning/runtime artifact until an adapted candidate clears an agentic gate.

vibethinker-3b-agentic-distilled

Status: blocked; model decision: inconclusive

HF repo: https://huggingface.co/posttrainllm/vibethinker-3b-agentic-distilled

The intended experiment was to distill agentic behavior into a reasoning-strong 3B base. The fused weights are public, but the repository does not preserve a current matched baseline, candidate eval, reasoning/breadth regression result, or ship decision. Public weights establish artifact existence, not success.

Release blockers:

Blocker Why it matters Unblock action
Before/after agentic eval missing There is no defensible tool-calling delta. Freeze and run the same baseline/candidate gate before any new training.
Reasoning retention missing Agentic adaptation may have damaged the base’s reason for being. Add a reasoning/breadth regression gate to the same evaluation.
No routing/package decision There is no recorded safe-use envelope. Package only after the frozen eval produces a ship, route, or reject decision.

hf-specialist-model-archive-v1

Status: report-only

Purpose: public storage index for model artifacts that were previously only durable because they existed in the local Mac cache. Hugging Face is now the public artifact store for unique posttrainllm weights and conversions; plain upstream base-model caches should be deleted locally instead of re-uploaded under posttrainllm.

  • Defog SQLCoder-7B-2 reports category-level Defog SQL-Eval scores, not one aggregate score.
  • Arctic-Text2SQL-R1 reports BIRD execution accuracy; use it as the public execution target lane, not as a direct comparison.
  • BFCL-V4 market rows on the website use the LLM Stats July 2026 snapshot only as directional context because that page marks the rows as self-reported and unverified. The official BFCL page remains the methodology/source-of-truth benchmark reference.

Release blockers:

Blocker Why it matters Unblock action
Public execution benchmark missing b-mc2 exact match is useful but not enough for a serious SQL model claim. Add BIRD Mini-Dev SQLite or Spider SQLite execution gate once DBs are local.
Not packaged under specialists/ Current adapter paths are local runs/ outputs, not package metadata. Create a package only after decision.json is ship; until then publish as report-only/candidate.
Output hygiene is weak Scorers extract the first SELECT; many completions still include prose after the query. Clean-SQL metric exists (scripts/sql/score_sql_clean_output.py); first hygiene candidate (ref-free SimPO) collapsed and was decided retry-training (runs/2026-07-03-sql-hygiene-dpo-qwen06/). Retry with reference-anchored DPO.
Performance numbers missing Public artifact should report latency, RAM, tok/s, and eval time. Run scripts/sql/measure_sql_routed_perf.py on the routed setup (offline smoke: evals/sql-perf-smoke.sh) and paste the report.
Data provenance needs public copy b-mc2 and BIRD-derived rows have different licenses/provenance surfaces. Add dataset license/provenance notes to the public report.

Next release action:

Publish qwen06-sql-routed-v1 as a public report artifact, not a shipped specialist package. The report should say: targeted 0.6B SQL adapter beats a small T5 baseline on the frozen public exact slice, but the robust artifact is a router over two specialists, and public execution benchmarking is the next gate.

Canonical local render:

python3 scripts/sql/render_sql_factory_run.py --out runs/2026-07-02-sql-routed-qwen06-v1

Spider execution gate once a local Spider bundle exists:

python3 scripts/sql/build_sql_spider_execution_gate.py \
  --spider-root /path/to/spider \
  --out evals/sql-spider-execution

Website page: /artifacts/qwen06-sql-routed-v1

Historical Release Order

The original public-artifact order has been completed and is retained as design history, not an active queue:

  1. qwen06-sql-routed-v1 is published report-only with failed attempts, routing, blockers, and measured improvement.
  2. qwen3-4b-file-ops-distilled weights are public with routed-only caveats.
  3. hf-specialist-model-archive-v1 links preserved wins and failed variants without presenting every public checkpoint as a product model.
  4. factory-run-schema-v1 links the routed SQL report as its canonical example; automatic schema-complete command output remains a future implementation target.
  5. The browser playground remains a learning lab rather than the factory control plane.
