HEAD TO HEAD
Jared Palmer: kev and SAGEA: mira, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | jared-palmer/kev | sagea/mira |
|---|---|---|
| Summary | An open family of System One models. A LoRA adapter plus a pointer head on a frozen Qwen base returns a distribution per typed question in one forward pass, serves TypeSafe's /v1/systemone contract, and ships a fitted temperature with every checkpoint. | 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.
kev is from Jared Palmer and mira from SAGEA. Both have open weights you can download and run. Both answer choice, score, noul, classify and route questions.
They report on different suites — kev 83.8% on transfer-v4 (locked, out of domain), mira 74.5% on s1-decision-bench — so the numbers do not rank them. Test both on your own labelled examples.
kev: Free (open weights). mira: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Yes, both: systemone pull jared-palmer/kev and systemone pull sagea/mira download the weights.
