# Omar (kouhxp): gutsy

> 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.

# gutsy-0.8b

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.

A full fine-tune of Qwen3.5-0.8B (embeddings frozen) on about 105,000 decision questions, with a cross-entropy plus Brier loss. Ships Q8_0 and Q4_K_M GGUF files with per-type temperature files and the gutsy-inference runtime, which serves /v1/systemone locally, caches the state and shortlists lists of more than 16 options. The maker's own runs on JevBench's public items (a third-party benchmark): 0.732 with Q8_0, 0.697 with Q4_K_M; calibration error is 0.022 on the maker's validation split but 0.107 and 0.137 on JevBench's original and hard tiers. Weak on date and number arithmetic, long multi-step policies and world knowledge. English only.

## What it decides

- **choice** — picks one option from a set
- **score** — places the input on an ordered scale
- **noul** — answers a yes/no question with one probability
- **classify** — assigns a category from a fixed taxonomy
- **route** — sends the input to one of several destinations
