Quotas and limits

This document contains current API restrictions, quotas, and limits on use of Dialogflow. We reserve the right to change these limits, and this page will be updated to reflect any changes.

Quotas

Quotas differ based on the Dialogflow edition and pricing plan. To find out more about the different Dialogflow editions, see Dialogflow Editions.

These quotas apply to each Dialogflow GCP project and are shared across all applications and IP addresses using a given GCP project. To request a higher quota, click an edit button for a quota on the Quotas tab of the Google Cloud Platform Dashboard, and then click Apply for a higher quota in the quota edit form to submit a Dialogflow Quota Increase Request.

If you use multiple projects, the consumer project is used to determine quotas.

The following table provides a quota comparison for editions and pricing plans.

* Quota increases for usage in the context of Actions on Google (Google Assistant) will be provided free of charge upon request for high quality actions.

** Each StreamingDetectIntent stream is considered a single request even though the stream might include multiple frames of StreamingDetectIntentRequest audio within the stream.

*** "Phone minutes per minute" is the total sum of time per minute that is used by all users making calls through the phone system. For example: in one 60-second time period one user is on for 60 seconds, a second for 30 seconds, and a third for 30 seconds. This is calculated as 2 minutes per minute. More minutes per minute allows more users to use the system simultaneously.
