Darwin-27B-ZTC-v2
Darwin-27B-ZTC-v2 is a zero-token decision model that takes a state and a typed question and returns probabilities for each option. It uses one forward pass per question and generates no tokens.
What it does
Use it to score possible decisions for a given state, such as selecting a customer-support response.

Evidence
6 claims- The model returns a probability for every option in a typed question. [1]
**A zero-token decision engine from the Darwin family, second version.** Darwin-27B-ZTC-v2 reads a piece of state and a typed question (`noul` yes or no, `choice` one of N labels, `score` an ordered rubric) and returns a probability for every option.

All 137 benchmarks complete, measured with the S1MB evaluator and its `autojev` adapter at revision `a8f283a`, then validated and merged by the S1MB maintainer ([results](https://huggingface.co/datasets/hotchpotch/s1mb-result/tree/main/FINAL-Bench__Darwin-27B-ZTC-v2)).

- The backbone weights are BF16 and about 54 GB. [1]
The layout is the same as v1: backbone weights (BF16, about 54 GB), `readout.safetensors`, `decision_config.json`, tokenizer, and the inference code in `autojev/` (from [autojev](https://github.com/denis-pplx/autojev), MIT, with text-only backbone support added).
