Quotas and limits
This document contains the current quotas and limits for use of Dialog ow. We reserve the right to change these constraints, and this page will be updated to re ect any changes.
De nitions
The following terms are used to describe pricing and quotas:
Request: A request is de ned as any call to the Dialog ow service, whether direct with API usage or indirect with integration or console usage. Depending on the task and design of the agent, the number of requests needed for an end-user to accomplish a task with a Dialog ow agent can vary greatly.
Consumer projects and resource projects: If you use multiple projects, it is possible that the project associated with your request authentication (consumer project) is not the same project that is associated with the agent in the request (resource project). In this case, the consumer project is used to determine prices and quotas. For more information, see Using multiple projects (/dialog ow/docs/multi-project).
Quotas
Quotas (/docs/quota) are default constraints applied to your project. If you are using a paid edition (/dialog ow/docs/editions), you can request a quota increase. The purpose of quotas is to throttle service load per client, which protects a service from being overloaded and a client from unexpected resource usage.
Dialog ow quotas vary, depending on the edition (/dialog ow/docs/editions) of your agent. Quotas apply to each project and are shared across all applications and IP addresses using a project.
The quotas listed below are the commonly encountered quotas. To review all quotas, see the GCP Console Dialog ow quotas (https://console.cloud.google.com/apis/api/dialog ow.googleapis.com/quotas) page. To request a higher quota, click Apply for a higher quota in the quota edit form to submit a Dialog ow Quota Increase Request.

Quotas table
The following tables provide a quota comparison for editions by agent type (/dialog ow/docs/editions#agent-types). Unless a feature is indicated as included, pricing and quotas are cumulative for all features used by a request.

Other session requests 100 requests per 100 requests per 100 requests per For example, setting minute minute minute session entities or updating/querying context.
† Each StreamingDetectIntent (/dialog ow/docs/how/detect-intent-stream) 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. # Features marked as unlimited are still potentially limited by use of other features. For example, if your edition provides unlimited quota for knowledge connectors, a text request that uses knowledge connectors is still limited by the quota for text requests. ¶ Google Assistant audio input and output is considered a text request.

Limits are xed constraints, which cannot be increased. Many resources and elds have count, duration, or length limitations, which are xed constraints for the service implementation.
The following tables list commonly encountered limits. Feature-speci c documentation and API reference documentation may provide additional limits.
Count limits
Description Limit
Maximum number of intents 2000
Maximum number of entity types (/dialog ow/docs/entities-overview#terminology) 250
Maximum number of training phrases per intent and per language * 2000
Maximum number of training phrases per agent and per language * 100,000
Maximum number of entity entries (/dialog ow/docs/entities-overview#terminology) 30000
Maximum number of entity synonyms per entity entry 200 (/dialog ow/docs/entities-overview#terminology)
Maximum number of entity reference values and synonyms 1,000,000 (/dialog ow/docs/entities-overview#terminology) per agent and per language *
Maximum number of parameters per intent 20
Maximum number of input contexts per intent 5
Maximum number of output contexts per intent 30
Maximum number of text responses per intent and per language * 30
Maximum number of prompts per parameter and per language † 30
Maximum number of agents per Google Cloud project 1
* All limits related to intents that have a language component are validated on a per language basis. For example, if your agent supports English and French, an intent can have at most 2000 English training phrases and 2000 French training phrases. † For example, if your agent supports English and French, a parameter can have at most 30 English prompts and 30 French prompts.
