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.
A Gemma 4 12B fine-tune for typed decisions that also chats and reads images. Ships as GGUF for llama.cpp, holds a 64K context on a 16 GB GPU, and serves /v1/systemone next to /v1/chat/completions.

Questions
What is the difference between startlux-decision and winnow?
startlux-decision is from StartLux and winnow from EldanRing. Both have open weights you can download and run. Both answer choice, score and noul questions. Only winnow answers classify and route. startlux-decision is the smaller model, at 4.7B parameters to 12B. startlux-decision is licensed cc-by-nc-4.0; winnow, apache-2.0.
Which is more accurate, startlux-decision or winnow?
They report on different suites — startlux-decision 88.3% on JevBench public set (231 items; 204 correct), maker's run, winnow 85.7% on JevBench public subset (231 items), Q8_0 — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, startlux-decision or winnow?
startlux-decision: Free (open weights). winnow: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Which is faster, startlux-decision or winnow?
By their publishers’ figures, startlux-decision answers in about 26 ms at the median and winnow in about 143 ms — measured on different hardware, so treat it as a rough guide.
Can I run startlux-decision or winnow locally?
Yes, both: systemone pull startlux/startlux-decision and systemone pull eldanring/winnow download the weights.
