SAGEA: mira and Upstage: solar-decide, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | sagea/mira | upstage/solar-decide |
|---|---|---|
| Summary | Small open typed-decision model with calibrated probabilities, first-class Nepali coverage. | Upstage's structured decision model, a System One endpoint on Solar Mini 4. Returns a choice, a score or a yes/no answer with a probability read from the model, in one forward pass, on the same /v1/systemone schema as Jev. |

Figures are from each model’s manifest; accuracy and latency are what the publishers report, on their own suites and hardware. Add a third model.
mira is from SAGEA and solar-decide from Upstage. mira has open weights you can download and run; solar-decide is only available as a hosted API. Both answer choice, score, noul, classify and route questions. mira is licensed apache-2.0; solar-decide, proprietary.
Only mira publishes an accuracy figure (74.5% on s1-decision-bench); solar-decide does not, so there is no comparison to make without your own test.
mira: Free (open weights). solar-decide: $0.1 / $0 per 1M. Open weights cost nothing per call beyond your own hardware.
mira yes — systemone pull sagea/mira downloads its weights. The other is only served as a hosted API.
