Omar (kouhxp): gutsy and StartLux: startlux-decision, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | kouhxp/gutsy | startlux/startlux-decision |
|---|---|---|
| Summary | Omar (kouhxp)'s CPU decision model: a Qwen3.5-0.8B fine-tune shipped as GGUF for llama.cpp that answers yes/no, choice and score questions with a probability per option plus a 'none of these' reject probability, served by a local Jev-style HTTP runtime. | StartLux's decision family in six sizes, 0.8B to a 35B-A3B mixture of experts. All questions in a request are answered in one forward pass, with a probability for every option, through a TypeSafe /v1/systemone-compatible server. Text, JSON or images, up to 256K tokens. |

Figures are from each model’s manifest; accuracy and latency are what the publishers report, on their own suites and hardware. Add a third model.
gutsy is from Omar (kouhxp) and startlux-decision from StartLux. Both have open weights you can download and run. Both answer choice, score and noul questions. Only gutsy answers classify and route. startlux-decision reads up to 256K tokens of state, against 8K tokens for gutsy. gutsy is the smaller model, at 800M parameters to 4.7B. gutsy is licensed apache-2.0; startlux-decision, cc-by-nc-4.0.
They report on different suites — gutsy 73.2% on JevBench public set (231 items; 169 correct), the maker's own run with Q8_0, startlux-decision 88.3% on JevBench public set (231 items; 204 correct), maker's run — so the numbers do not rank them. Test both on your own labelled examples.
gutsy: Free (open weights). startlux-decision: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Yes, both: systemone pull kouhxp/gutsy and systemone pull startlux/startlux-decision download the weights.
