SAGEA: mira and Respan: span-01, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | sagea/mira | respan/span-01 |
|---|---|---|
| Summary | Small open typed-decision model with calibrated probabilities, first-class Nepali coverage. | Respan's behaviour-scoring model for evals, guardrails and monitoring. For each plain-language behaviour you define, it reads a conversation or agent trace and returns the probability the behaviour is present, absent or not observable, in one forward pass. |

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 span-01 from Respan. mira has open weights you can download and run; span-01 is only available as a hosted API. Both answer noul and classify questions. Only mira answers choice, score and route. mira is licensed apache-2.0; span-01, proprietary.
Only mira publishes an accuracy figure (74.5% on s1-decision-bench); span-01 does not, so there is no comparison to make without your own test.
mira: Free (open weights). span-01: $0.02 / $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.
