Alternatives verification refresh
Run run:43f334f1-e973-474c-b958-e9073b3764cf revisits the six alternatives already named on the public page. It is a conservative local-artifact refresh, not a live project audit.
Executive finding: no verified open-weight Jev model was found in this refresh. This is a verification-status negative finding—not evidence that no such model exists.
Verification boundary: the runner did not open or live-check the six direct repositories or documentation sets, package registries, model files, APIs, or runtimes. The current matrix therefore upgrades no row. All current project facts remain unknown.
What this refresh can and cannot say
| Question | Current public conclusion | Why it remains open |
|---|---|---|
| Is this the Jev model? | Unknown for all six rows. No model identity, weights, provenance, or parity was freshly checked. | API shape, project name, or a prior inventory label does not establish model equivalence. |
| Does it preserve a System One-like API? | Unknown for all six rows. No Choice, Score, Noul, option-probability, error, or retry behavior was tested. | A compatible-looking SDK or output example needs a direct interface check. |
| Can it run locally and privately? | Unknown for all six rows. Hardware, weights, licence, network, telemetry, storage, and data handling were not inspected. | “Open,” “local,” or “classifier” labels in an inventory are not runtime evidence. |
| What workflow does it replace? | Prior inventory labels are retained as orientation only; current fit is unknown. | An adapter, classifier, generative model, or teaching bench may replace a different layer than Jev. |
| What are cost and latency trade-offs? | Unknown for all six rows. No fresh price, latency, calibration, evaluation, or maintenance evidence was produced. | Do not infer performance or cost from stars, names, underlying models, or stale descriptions. |
Six retained entries
| Entry | Direct URL retained from the supplied page | Current status |
|---|---|---|
| system-one-adapter-python | github.com/typesafe-ai/system-one-adapter-python | Unknown. Not fetched in this refresh; historical label: official adapter. |
| SemIf / OpenJev | github.com/TheoLeeCJ/SemIf | Unknown. Not fetched in this refresh; historical label: local open model. |
| jevlike | github.com/vinnylarouge/jevlike | Unknown. Not fetched in this refresh; historical label: research project. |
| mini-Jev | github.com/r-ms/mini-jev | Unknown. Not fetched in this refresh; historical label: teaching bench. |
| GLiClass | github.com/Knowledgator/GLiClass | Unknown. Not fetched in this refresh; historical label: classifier. |
| General LLM + structured output | No specific implementation URL was supplied in the existing page inventory. | Unknown. No provider or implementation was selected for live verification; historical label: baseline. |
Follow-up before an upgrade
- Inspect each direct project. Record the checked commit or release, licence, model files, provenance, and whether any weights exist.
- Exercise the interface. Test state, typed choices, scores, yes/no probabilities, changing options, errors, retries, and output semantics against a pinned fixture.
- Check the data boundary. Run in a clean environment and inspect device requirements, outbound network calls, telemetry, storage, and retention statements.
- Compare the job, not just the API. Measure accuracy, calibration, latency, memory, cost, and maintenance on the same decision set; do not publish unsupported benchmark numbers.
Evidence trail
- Public six-row alternatives matrix — the supplied local artifact reviewed for this refresh.
- system-one-adapter-python, SemIf, jevlike, mini-Jev, and GLiClass — direct URLs retained from that artifact for future checks; none was opened in this run.
- General LLM + structured output — no specific direct implementation URL was supplied, so no external source is asserted here.
This report records what was and was not verified on 21 September 2026. It does not upgrade any alternative, establish current licence or price facts, or prove that an open-weight Jev model does not exist.
