An independent Jev-shaped reproduction on DeBERTa-v3-large. One state and any number of choice, score and yes/no questions go in, and a calibrated distribution per question comes out of one forward pass. Public gold labels only.
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.

open-jev-deberta-v3-large is from Kotoba Labs and solar-decide from Upstage. open-jev-deberta-v3-large has open weights you can download and run; solar-decide is only available as a hosted API. Both answer choice, score, noul and classify questions. Only solar-decide answers route. solar-decide reads up to 512K tokens of state, against 512 tokens for open-jev-deberta-v3-large. open-jev-deberta-v3-large is licensed apache-2.0; solar-decide, proprietary.
Which is more accurate, open-jev-deberta-v3-large or solar-decide?
Only open-jev-deberta-v3-large publishes an accuracy figure (85.4% on Kotoba held-out test, seen question types (banking77, SST-5, BoolQ)); solar-decide does not, so there is no comparison to make without your own test.
Which is cheaper, open-jev-deberta-v3-large or solar-decide?
open-jev-deberta-v3-large: Free (open weights). solar-decide: $0.1 / $0 per 1M. Open weights cost nothing per call beyond your own hardware.
Can I run open-jev-deberta-v3-large or solar-decide locally?
open-jev-deberta-v3-large yes — systemone pull kotoba-labs/open-jev-deberta-v3-large downloads its weights. The other is only served as a hosted API.
