Shanghai AI Laboratory's multimodal decision model. A fine-tune of Qwen3.5-4B's language backbone (vision tower frozen) that answers up to 16 Choice, Score and Noul questions about a state and up to eight images in one forward pass, with a fitted calibration temperature.
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.

Questions
What is the difference between intern-decision and solar-decide?
intern-decision is from InternLM (Shanghai AI Laboratory) and solar-decide from Upstage. intern-decision has open weights you can download and run; solar-decide is only available as 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 intern-decision. intern-decision is licensed apache-2.0; solar-decide, proprietary.
Which is more accurate, intern-decision or solar-decide?
Only intern-decision publishes an accuracy figure (80.6% on LocalLLaMA/typed-decisions test split (400 cases, 2,000 decisions)); solar-decide does not, so there is no comparison to make without your own test.
Which is cheaper, intern-decision or solar-decide?
intern-decision: Free (open weights). solar-decide: $0.1 / $0 per 1M. Open weights cost nothing per call beyond your own hardware.
Can I run intern-decision or solar-decide locally?
intern-decision yes — systemone pull internlm/intern-decision downloads its weights. The other is only served as a hosted API.
