Vertex AI Agents pricing

Vertex AI Agent Builder provides the ability to quickly build virtual agents (chatbots) that generate answers based on the content (website, documents) you include in data stores. Using Vertex AI Agents, you can create a new Dialogflow CX virtual agent OR add the feature to an existing Dialogflow CX virtual agent.

To add additional generative AI capabilities to your Dialogflow CX virtual agents, you can leverage Generative Fallbacks which use a large language model (LLM) to gracefully handle scenarios where there is no match to the user's intent. Generators empower your bot builders to inject generative actions anywhere in your conversational flow — this could be to summarize a conversation, personalize an interaction, or chain multiple LLM calls together to create an entire generative workflow.

Pricing for Vertex AI Agents GA functionality

Vertex AI Agents Chat* $12.00 / 1,000 query**
Vertex AI Agents Voice* $0.002 / second†
Dialogflow CX Chat***(Standard, non-Generative AI capabilities for Chat) $7.00 / 1,000 query**
Dialogflow CX Voice***(Standard, non-Generative AI capabilities for Voice) $0.001 / second†
*All generative AI capabilities - Datastore agents, Generative Fallbacks, and Generators are included within Vertex AI Agents Chat and Voice SKU pricing.

*Customers can combine Dialogflow CX (non-generative) and Vertex AI Agents (generative) queries/seconds in the same agent or flow, and will automatically be charged for the actual usage of each feature set. This allows you to selectively leverage generative AI where applicable and only pay for what you actually use.

**Request (or Query): Billing metered per individual Request or Query.
A request or query is defined as any API call to the Dialogflow service or Vertex AI Agents service, whether direct with API usage or indirect with integration or console usage.
For example, a user asking a virtual agent (chatbot) a question and the chatbot responding is 1 Request. A user interaction with the chatbot can be made up of multiple Requests to accomplish a task.

† Includes speech recognition, speech-to-text (STT), speech synthesis, text-to-speech (TTS), and telephony. The total billed audio processing duration is independent of any no-charge, non-audio processing (API latency, webhook processing, and so on) which may occur before, during, or after audio processing.

* Dialogflow CX Chat and Dialogflow CX Voice are not eligible for the $1,000 FREE trial credits. Dialogflow CX has an additional trial credits program that can be combined with this Vertex AI Agent Builder FREE trial credit program. See additional definitions of Dialogflow CX metering here.

*Query: Billing metered per individual Request or Query Input
A request or query is defined as any API call to Enterprise Search, whether direct with API usage or indirect with integration or console usage.
Example: a user asking a natural language question and the Search Engine responding is 1 query.
(Autocomplete suggestions do not count as queries; a query is counted only when the user submits a final search query.)

** LLM Add-On is added to a Query to augment the processing to use a Generative AI feature,
LLM Add-On can be used interchangeably with either Search Standard Edition or Search Enterprise Edition.
Example: executing a Search Enterprise query with a Summarization request = 1 Search Enterprise query + 1 LLM Add-On query

Pricing for Vertex AI Agent Builder Index Data Storage

Data Indexed $5.00 / GiB per month
* Free quota of 10 GiB per month provided
** Shared across Vertex AI Agent Builder
*** Storage is calculated as 500 kibibytes (KiB) * "number of pages on website", where 1 KiB is 1,024 bytes. (500 KiB is ~0.000477 GiB; so data indexing pricing for a 1000 page website is $2.38 per month.)

Vertex AI Search for Media Recommendations pricing

The only Media Recommendations operations that incur charges are training, tuning, or requesting predictions by calling the recommend method. There's no charge for importing or managing user events or document information.

Training (per node per hour) costs are charged on a daily basis if your model is actively training or if you have submitted a request to resume training. After you pause or delete a model, you are no longer charged. See the documentation for managing training.

Tuning (per node per hour) costs for active models are charged after the tune completes successfully. You are only charged for an incomplete tune if you pause or delete a model during an ongoing tune. In this case, you are then charged for the node hours that were consumed before the model tuning stopped. See the documentation for managing tuning.

Predictions $0.27 / 1,000 prediction
Training and Tuning $2.50 per node per hour

Pricing Example for Media Recommendations


  • 10,000,000 prediction requests a month

  • Trains a single model per day, which automatically retrains once per day

  • Amounts to about 150 node hours of model training and 30 hours of model tuning per month

SKU Volume Rate Total List Price
10M predictions * $0.27 / 1k predictions = $2,700
150 node hours (Training) * $2.50 / hour = $375
30 node hours (Tuning) * $2.50 / hour = $75
Total $3,150

Google Cloud Observability charges

Media Recommendations logs an error to Google Cloud Observability for each API request that results in an error, such as a user event request that contains malformed JSON, or a document import request with a negative price. Media Recommendations also logs an error for every prediction request with a document that is not in the imported datastore.

Google Cloud Observability charges by the GiB of logs stored and for retention beyond the default retention period. For details about the free allotment and data retention, see the Google Cloud Observability pricing page.

The size of the logging data depends on the size of your JSON payload, but a GiB would be approximately 200,000 Media Recommendations errors.
