Seed 2.1 Lite

Seed 2.1 Lite is available in Volcano Engine. Its separate System One beta interface returns fixed-choice probabilities, yes-or-no probabilities or scores.

Technical guide

The decision request separates the evidence in state from the questions and criteria. Multiple independent decisions can share one input. The result includes probability data that application code can use.System One decision evaluation beta

Practical use

Practical guidance. For routing or moderation, define the decision boundary before calling the model. Measure false positives on your own examples. The returned score is a model estimate, so it does not establish that an action is justified.
