Andy Zhang: ajev and SAGEA: mira, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | andy-zhang/ajev | sagea/mira |
|---|---|---|
| Summary | An open Jev-style decision model by Andy Zhang: a LoRA adapter on Gemma 4 26B-A4B (also on Gemma 4 12B) that reads a state and returns a temperature-calibrated probability for every option of a yes/no, choice or score question in one forward pass. | 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.
ajev is from Andy Zhang and mira from SAGEA. Both have open weights you can download and run. Both answer choice, score and noul questions. Only mira answers classify and route.
Only mira publishes an accuracy figure (61.3% on s1-decision-bench); ajev does not, so there is no comparison to make without your own test.
ajev: Free (open weights). mira: Free (open weights). Open weights cost nothing per call beyond your own hardware.
By their publishers’ figures, mira answers in about 30 ms at the median and ajev in about 49 ms — measured on different hardware, so treat it as a rough guide.
Yes, both: systemone pull andy-zhang/ajev and systemone pull sagea/mira download the weights.
