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.
FLock.io's typed-decision model, fine-tuned from Mapika's decider-2b. Reads one hidden state per question and scores the declared options, so an answer outside the list cannot occur; several questions about one state share a forward pass.

Questions
What is the difference between solar-decide and this-that-model?
solar-decide is from Upstage and this-that-model from FLock.io. solar-decide is only available as a hosted API; this-that-model has open weights you can download and run. Both answer choice, score and noul questions. Only solar-decide answers classify and route. solar-decide is licensed proprietary; this-that-model, mit.
Which is more accurate, solar-decide or this-that-model?
Only this-that-model publishes an accuracy figure (87.8% on limberc/this-that-complex-decisions (1,710 questions, FLock's benchmark)); solar-decide does not, so there is no comparison to make without your own test.
Which is cheaper, solar-decide or this-that-model?
solar-decide: $0.1 / $0 per 1M. this-that-model: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run solar-decide or this-that-model locally?
this-that-model yes — systemone pull flock-io/this-that-model downloads its weights. The other is only served as a hosted API.
