POST /_inference/decision/{inference_id}

Auth

Answer a set of named questions about an input, such as whether a customer is complaining, which team should handle a request, or how angry a customer is. The questions are defined in the task settings of the inference endpoint, and can be replaced for a single request through task_settings.

Note

Only the elastic service currently supports the decision task.

Required privileges

Path parameters

inference_id string required: The unique identifier for the inference endpoint.

Query parameters

timeout union oneOf · default: 30s: The amount of time to wait for the inference request to complete.; Values: -1 0

Request body

input union oneOf required

The input to answer the questions about. It can be specified as a string, or as an object. The object form additionally allows specifying images.

}
		
	

One of:

task_settings object

Task settings for the individual inference request. These settings override the task settings specified when creating the inference endpoint.

questions map string to oneOf: The questions to answer, keyed by question name. The answers in the response use the same names. The questions replace the ones of the inference endpoint as a whole. At least one question is required.
