Whenever you run a model, you’re creating a prediction.

Some models run very quickly and can return a result within a few milliseconds. Other models can take longer to run, especially generative models, like the kind that produce images from text prompts.

Prediction statuses

Predictions can have any of the following statuses:

• starting: the prediction is starting up. If this status lasts longer than a few seconds, then it’s typically because a new worker is being started to run the prediction. Refer to cold boots.
• processing: the predict() method of the model is currently running.
• succeeded: the prediction completed successfully.
• failed: the prediction encountered an error during processing.
• canceled: the prediction was canceled by the user.

Timeouts

Predictions time out after running for 30 minutes. If you require more than 30 minute timeouts for predictions, contact us.

Monitoring predictions

When you’re logged in, you can view a list of your predictions on the dashboard, with summaries of status, run time, etc.

For long-running models, you may want to poll the API or use webhooks to check the status of a prediction.

To learn more about how long predictions are stored with Replicate, refer to Data retention.
