Alibaba Model Studio adds decision-model-preview on the System One protocol
Alibaba Cloud Model Studio documents a hosted decision model, decision-model-preview, on the TypeSafe System One request shape. The model-info page was last updated on 11 October 2026.
The call is POST /compatible-mode/v1/systemone with state and named questions. Question types are choice, noul and score. The Python examples use typesafe-sdk pointed at the Bailian gateway. The docs list a 65,536-token context and a max output length of 0, which matches the claim that the endpoint does not generate text. Rate limits on the model-info page are 1,200 requests per minute and 2,000,000 tokens per minute in both China (Beijing) and Singapore. Both regions list the price as limited-time free. The page does not say when that ends.
The docs name Alibaba Cloud Model Studio as the inference provider. They do not name Jev, TypeSafe weights, or a training recipe. A matching protocol is not evidence that the model underneath is Jev.
