A Gemma 4 12B fine-tune with merged weights for the decisio runtime. Its commit rule pushes yes/no probabilities inside the 0.20 to 0.80 band to that band’s edge on the same side. This preserves the winning answer while changing calibration.

## Facts

- Base and size: Gemma 4 12B; merged bf16 weights
- Inputs: State and typed choice, yes/no or score questions
- Runtime: decisio 0.35.0 or later; plain vLLM does not apply the full readout
- Licence: Apache-2.0, per card and included licence
- Access: Public weight shards and decision\_config.json

## Claims and sources

- **VENDOR-REPORTED**: The maker says temperatures were fitted by log loss and training was checked against both boards’ public test sets. Training data are undisclosed; the card supplies no task-accuracy result. [source](<https://huggingface.co/tachara-ai/Decisio-12b-tuned-v2-commit>)
