Final status and routine-monitoring closure
Run run:62ac219d-07c9-40e4-821d-f07cdeec9e53 · final cutoff 2026-09-24T00:36:00Z UTC · bounded public, lawful, read-only primary-source sweep. Direct inference/access requests: n=0.
stealth/union-alpha. The former Go alias is absent from the three inspected current Go surfaces. Current paid unbiased/pareto is separate and not shown to be a fixed continuation of either former alias.Evidence gates
| Evidence question | Required evidence | R5 result |
|---|---|---|
| Former-preview attribution | Direct first-party language | Met only for historical OpenRouter preview → Pareto by Unbiased. R5-S01 |
| Former Go alias → Pareto | Direct source language naming the Go alias and Pareto | Not met. Go-source omission is not mapping evidence. R5-S05 |
| Fixed equivalence | Version, configuration, and date pin joining a former alias to Pareto | Not met. Current catalog metadata and a canonical slug do not meet this gate; terms permit composition changes. R5-S02 · R5-S07 |
| Benchmark result | Stable raw artifact, fixed model/version/date, dataset/task IDs or n, harness/settings, and result/cost method | Not met for Union Alpha or an independently reproducible Pareto result. Provider claims and configurable harness remain separate. R5-S06 · R5-S08–09 |
No Pareto score can be called a Union Alpha benchmark without the fixed-linkage gate.
R4 → R5 decision table
| Field | R5 decision | Boundary |
|---|---|---|
| Old-slug / re-listing status | Unchanged | Historical page says the free stealth period ended; public catalog has no stealth/union-alpha match. This is not an old-ID request result. R5-S01 · R5-S02 |
| Former Go alias status | Unchanged | No alias match in inspected Go docs, public catalog, or changelog. Absence applies only to those sources. R5-S05 |
| Explicit alias → Pareto mapping | Unchanged / partial | OpenRouter explicitly maps the former OpenRouter preview, not the former Go alias, to Pareto. R5-S01 |
| Fixed Pareto version/configuration mapping | Unchanged: none found | unbiased/pareto-20260917 is current route metadata, not mapping language; terms permit mutable composition. R5-S02 · R5-S07 |
| Current Pareto route, price, declared limits/capabilities, and data terms | Unchanged | Current listing metadata and Unbiased terms are separately scoped. None transfers to former aliases. R5-S03 · R5-S07 |
| Numeric route-specific quota | Unchanged: none found | Limits material is generic; no inspected source publishes a numeric cap for former aliases or Pareto. R5-S04 |
| Immutable raw benchmark/result package | Not inspectable / no qualifying inspected artifact | Landing and method files are configurable; release/results URLs had browser-cache misses. This does not prove absence. R5-S08–09 |
| Independent reproducible result | Unchanged: none established | The provider card is provider-published; its n=30 comparison is preliminary and not independently validated. R5-S06 |
Route-specific rate-limit conclusion
| Route | Published route-specific numeric limit at cutoff | Direct observation | Conclusion |
|---|---|---|---|
Historical stealth/union-alpha | None found in inspected current primary sources | 0 | Unknown. Catalog omission is not a quota, error, or entitlement result. |
| Former OpenCode Go alias | None found; alias absent from inspected current sources | 0 | Unknown. Do not reuse current Go estimates for other named models. |
Current unbiased/pareto | per_request_limits: null; no numeric quota found | 0 | Unknown. null does not mean unlimited. Generic policy is not a route-specific quota. |
Exact R5 answer: no inspected current primary source publishes a numeric route-specific cap for either former alias or current Pareto, and R5 made zero direct requests.
Performance record boundary
Unbiased’s model card publishes a Pareto 26.9 headline slate: DeepSWE 74, Terminal-Bench 4.0 51, MMMU-Pro 78, HLE no-tools 49, and ArXivMath 88. It also publishes a preliminary DeepSWE 30-task point: 70.0%, USD 0.29/task, Sep. 20. The card says that point was screenshot-transcribed, not independently validated, and needs denominator and cost-method confirmation. The public pareto-evals repository provides configurable method code and documents local output; it does not provide a fixed former-alias mapping or qualifying immutable run package on the inspected surfaces. These are not Union Alpha benchmark results. R5-S06 · R5-S08–09
Decision and reopen triggers
- R6 — fixed-linkage verification: a first-party source explicitly maps a former Union Alpha alias to a named Pareto version, configuration, and date.
- R7 — benchmark-artifact audit: an immutable raw Pareto result package or independently reproducible result appears with the required method fields.
- R8 — official re-listing/access observation: a former alias is officially re-listed or explicitly mapped to an active route, with a separately approved low-risk protocol and pre-existing authorized credential.
- R9 — material route-policy delta: a first-party source changes Pareto price, a numeric route-specific limit, retention/data terms, or retirement/replacement status.
Capture limits
Source ledger, capture notes, collection method, request count, and checksums are retained with the R5 run. Browser captures are excerpt and absence notes, not raw HTTP bodies. Release/results sub-surfaces were not inspectable because of browser-cache misses; that limitation does not establish absence.
