}Authorizations
Most Arize AI endpoints require authentication. For those endpoints that require authentication, include your API key in the request header using the format
Path Parameters
The unique alignment task identifier (base64) A universally unique identifier (base64-encoded opaque string).
"RW50aXR5OjEyMzQ1"
Response
Returns the new alignment task
A reusable comparison of evaluator labels and human annotations on a dataset. The dataset, label column, annotation column, and comparison function identify the task. The name does not affect task identity.
The unique identifier for the alignment task
When the alignment task was created
When the alignment task was last modified
The name of the alignment task
The identifier of the dataset that contains the labels and annotations
The dataset column holding the evaluator's labels, for example
eval.hallucination.label when the labels are already on the dataset, or
output.label when an experiment produces them.
The dataset column holding the human annotations to compare against
How an alignment task compares a judge label to a human annotation.
- EXACT_MATCH - Labels agree when their values are equal. The score is the fraction of comparable rows that agree.
