# decision-model-preview

Alibaba Cloud Model Studio's hosted decision model, in preview. One request carries a state and several typed questions (choice, noul, score); a single forward pass returns a probability distribution per question and generates no text. Free for a limited time.

Hosted only; no weights, base model or evaluation numbers are published. Served at POST /compatible-mode/v1/systemone on per-workspace endpoints in Singapore and Beijing, and Alibaba's docs use the TypeSafe SDK as the client. Choice takes up to 255 options, score 2 to 255 levels (3 to 7 recommended) and noul returns P(yes); choice and score also return a confidence. 65,536-token context, about 16 questions per request recommended, 1,200 RPM and 2M TPM per region. Listed as a limited-time free preview. A fine-tuning guide describes custom snapshots trained on soft labels, enabled through an Alibaba account manager. Not yet measured on the third-party JevBench board.

## 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
