Arc53: arc-decide and SAGEA: mira, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | arc53/arc-decide | sagea/mira |
|---|---|---|
| Summary | A 0.6B decision model on Qwen3-0.6B-Base from the DocsGPT team. Give it a state and typed questions (yes/no, a choice of up to 16 options, a 3- or 4-level score) and it returns calibrated probabilities in one pass, for RAG and agent checks. | Small open typed-decision model with calibrated probabilities, first-class Nepali coverage. |

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.
arc-decide is from Arc53 and mira from SAGEA. Both have open weights you can download and run. Both answer choice, score, noul, classify and route questions. Only arc-decide answers rank. arc-decide is licensed mit; mira, apache-2.0.
Only mira publishes an accuracy figure (61.3% on s1-decision-bench); arc-decide does not, so there is no comparison to make without your own test.
arc-decide: Free (open weights). mira: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Yes, both: systemone pull arc53/arc-decide and systemone pull sagea/mira download the weights.
