Upstage's structured decision model, a System One endpoint on Solar Mini 4. Returns a choice, a score or a yes/no answer with a probability read from the model, in one forward pass, on the same /v1/systemone schema as Jev.
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 solar-decide and standard-one?
solar-decide is from Upstage and standard-one from Standard Thinking. solar-decide is only available as a hosted API; standard-one has open weights and a hosted API. Both answer choice, score, noul, classify and route questions. solar-decide reads up to 512K tokens of state, against 8K tokens for standard-one. solar-decide is licensed proprietary; standard-one, apache-2.0.
Which is more accurate, solar-decide or standard-one?
Only standard-one publishes an accuracy figure (71.1% on typed-decisions suite, 400 cases / 2,000 decisions (maker's served run, v2)); solar-decide does not, so there is no comparison to make without your own test.
Which is cheaper, solar-decide or standard-one?
solar-decide: $0.1 / $0 per 1M. standard-one: Hosted, price not published, or free to self-host. Open weights cost nothing per call beyond your own hardware.
Can I run solar-decide or standard-one locally?
standard-one yes — systemone pull standard-thinking/standard-one downloads its weights. The other is only served as a hosted API.
