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.
Standard Thinking's decision model. Ministral 3 8B with a merged LoRA, served through stock SGLang and an open jev-adapter that exposes /v1/systemone and scores the supplied options in one forward pass with per-type temperatures.

Questions
What is the difference between kev and standard-one?
kev is from Jared Palmer and standard-one from Standard Thinking. kev has open weights you can download and run; standard-one has open weights and a hosted API. Both answer choice, score, noul, classify and route questions. kev is the smaller model, at 4.0B parameters to 8.0B.
Which is more accurate, kev or standard-one?
They report on different suites — kev 83.8% on transfer-v4 (locked, out of domain), standard-one 71.1% on typed-decisions suite, 400 cases / 2,000 decisions (maker's served run, v2) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, kev or standard-one?
kev: Free (open weights). standard-one: Hosted, price not published, or free to self-host. Open weights cost nothing per call beyond your own hardware.
Can I run kev or standard-one locally?
Yes, both: systemone pull jared-palmer/kev and systemone pull standard-thinking/standard-one download the weights.
