API ReferencePredictions

Create prediction

POST

If you have predictions generated for your dataset from a model, either as pre-annotated tasks or pre-labeled tasks, you can import the predictions with your dataset into Label Studio for review and correction.

To import predicted labels into Label Studio, you must use the Basic Label Studio JSON format and set up your tasks with the predictions JSON key. The Label Studio ML backend also outputs tasks in this format.

JSON format for predictions

Label Studio JSON format for pre-annotations must contain two sections:

  • A data object which references the source of the data that the pre-annotations apply to. This can be a URL to an audio file, a pre-signed cloud storage link to an image, plain text, a reference to a CSV file stored in Label Studio, or something else.
  • A predictions array that contains the pre-annotation results for the different types of labeling. See how to add results to the predictions array.

For more information, see the JSON format reference in the Label Studio documentation

Request

This endpoint expects an object.
task
integerOptional
Task ID for which the prediction is created
result
list of maps from strings to anyOptional

Prediction result in JSON format. Read more about the format in the Label Studio documentation.

score
doubleOptional
Prediction score. Can be used in Data Manager to sort task by model confidence. Task with the lowest score will be shown first.
model_version
stringOptional
Model version - tag for predictions that can be used to filter tasks in Data Manager, as well as select specific model version for showing preannotations in the labeling interface
