Telnyx: decision-flash and Omar (kouhxp): gutsy, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | telnyx/decision-flash | kouhxp/gutsy |
|---|---|---|
| Summary | Telnyx's hosted decision models, in beta on Telnyx Inference. One request carries shared state and up to 64 typed questions (choice, yes/no noul, ordered score) and returns a probability per option, with no generated text, on a TypeSafe-compatible /v1/systemone route. | 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. |

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.
decision-flash is from Telnyx and gutsy from Omar (kouhxp). decision-flash is only available as a hosted API; gutsy has open weights you can download and run. Both answer choice, score, noul, classify and route questions. decision-flash is licensed proprietary; gutsy, apache-2.0.
Only gutsy publishes an accuracy figure (73.2% on JevBench public set (231 items; 169 correct), the maker's own run with Q8_0); decision-flash does not, so there is no comparison to make without your own test.
decision-flash: $0.035 / $0 per 1M. gutsy: Free (open weights). Open weights cost nothing per call beyond your own hardware.
gutsy yes — systemone pull kouhxp/gutsy downloads its weights. The other is only served as a hosted API.
