A typed-decision layer for Google's DiffusionGemma, from David Villalón at Maisa AI. It compiles a request into a small answer canvas, runs one denoising read on patched vLLM and reads the probabilities of the allowed labels, for text, images and images offered as options.
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.

Questions
What is the difference between djev and open-jev-deberta-v3-large?
djev is from Maisa and open-jev-deberta-v3-large from Kotoba Labs. djev has open weights and a hosted API; open-jev-deberta-v3-large has open weights you can download and run. Both answer choice, score and noul questions. Only open-jev-deberta-v3-large answers classify. open-jev-deberta-v3-large is the smaller model, at 434M parameters to 26B.
Which is more accurate, djev or open-jev-deberta-v3-large?
Only open-jev-deberta-v3-large publishes an accuracy figure (85.4% on Kotoba held-out test, seen question types (banking77, SST-5, BoolQ)); djev does not, so there is no comparison to make without your own test.
Which is cheaper, djev or open-jev-deberta-v3-large?
djev: $0.035 / $0 per 1M, or free to self-host. open-jev-deberta-v3-large: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run djev or open-jev-deberta-v3-large locally?
Yes, both: systemone pull maisa/djev and systemone pull kotoba-labs/open-jev-deberta-v3-large download the weights.
