One input. Typed decisions.

Illustrative values · No API call

Shared input

“My subscription was charged twice this month. I can’t update my card, and this is my second message. Please help.”

Pass text or JSON as shared state. Ask several questions in one request; each is evaluated independently against that same input.

Which team should handle this?

Billinghighest-probability option

Billing: 82%
Technical: 13%
Account: 5%

Define a set of categories. The model returns the most likely option and the probability of every option, adding up to 100%.

Confidence

Read the whole distribution.

The winning option is only part of the answer. A clear preference and a close call can both select “Billing”. Their distributions show how much ambiguity remains.

Use the returned probabilities to choose an action or send ambiguous results for human review. Probability is not a guarantee of correctness.

Clear preference

Billing: 90%
Technical: 7%
Account: 3%

Close call

Billing: 36%
Technical: 34%
Account: 30%

Limits

Building with Decider Flash V1.2 4B

Availability follows the qualified catalog and your API key permissions. If the qualified route is unavailable, requests return 503 before a credit hold or provider call.

Text and JSON in, typed answers out: State can be a string, object or array. This model accepts text input, without audio, images or streaming.
One state, independent questions: Batch up to 64 questions. If a question needs a previous answer, make a separate call. Extra questions still use input tokens.
Your categories and scale: Up to 64 options per choice; 2–10 ordered levels per score. Describe each option clearly, and add an “other” option when categories are not exhaustive.
32 KiB normalized request limit: The upstream JSON must fit within 32,768 UTF-8 bytes, including routing fields MiniRouter adds.

Example

HTTP example

Use an explicit model and an integration API key. Disable automatic retries: a lost response may still incur cost.
