Our take
AI-assisted analysis based on the sources below. Suitability is an editorial assessment; test it on your own workload.
upstage/solar-decide (canonical slug upstage/solar-decide-20260928) is Upstage's structured decision model listed on OpenRouter with a text->decisions modality. The catalog description says callers submit a state plus typed questions and receive a choice, and frames it as a System One endpoint running on Solar Mini 4. The listing reports a very large context window but includes no benchmarks or measured results. All information here is catalog-reported, not independently verified.[1]
Strengths
- Dedicated decision output: the catalog describes a text->decisions modality that returns choices for typed questions rather than free-form text.[1]
- The catalog reports a very large context window, suggesting room for extensive state descriptions in a single request.[1]
- It is described as a System One endpoint on Solar Mini 4, a framing that suggests positioning for fast decision calls.[1]
Limitations
- No benchmark scores, arena results, or other measured performance appear in the source; all capability claims are catalog-reported, not measured.[1]
- The only evidence is the OpenRouter catalog; an independent model card was not available in this source pack, so validate behavior on your own workloads before relying on it.[1]
- The catalog shows an empty supported-parameters field and no reasoning or knowledge-cutoff information; treat these as unreported, not confirmed absences.[1]
Where to use it
- Possible fit, unverified: routing requests to a fixed set of actions, where the typed-question-to-choice pattern described in the catalog could replace parsing free-form text.[1]
- Possible fit, unverified: decision steps inside agents or workflows that can already express their state as text plus typed questions.[1]
- Possible fit, unverified: screening long inputs in a single decision call, given the catalog-reported large context window; confirm accuracy before production use.[1]

Tasks and capabilities
A grade appears only where the source supplies a matching measurement for that task, the model is active and the cohort holds at least 10 comparable models. The capability column lists facts the source declares — supported formats, reasoning and tool parameters — which are not measured quality.
| Task | Grade | Source-declared capability |
|---|---|---|
| General quality | No measurement | — |
| Coding | No measurement | — |
| Agents | No measurement | — |
| Writing | No measurement | — |

How grades work
Each letter grade compares a model only against other models scored by the same source and metric in the current snapshot. S means the top 10%, A the next 20%, B the next 30%, C the rest. Models without a published measurement are shown as not rated — a supported format alone never implies measured quality.
- S — S — top 10% of the cohort
- A — A — next 20% of the cohort
- B — B — next 30% of the cohort
- C — C — below the B band
