Liquid AI's first decision model, served only through the Liquid API. Returns Choice, Score and Noul answers with probability distributions and zero output tokens, on the /v1/systemone request shape used by TypeSafe's SDK.
StartLux's decision family in five sizes, 0.8B to 27B. All questions in a request are answered in one forward pass, with a probability for every option, through a TypeSafe /v1/systemone-compatible server that records CUDA graphs for short requests.

Which is more accurate, d1 or startlux-decision?
Only startlux-decision publishes an accuracy figure (88.3% on JevBench public set (231 items; 204 correct), maker's run); d1 does not, so there is no comparison to make without your own test.
Which is cheaper, d1 or startlux-decision?
d1: Hosted, price not published. startlux-decision: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run d1 or startlux-decision locally?
startlux-decision yes — systemone pull startlux/startlux-decision downloads its weights. The other is only served as a hosted API.
