I would like to understand what price will generate my chatboot developed in Dialog Flow CX. I have read the page https://cloud.google.com/dialogflow/pricing but it is not entirely clear to me.

With Dialogflow CX, you pay per session? by request? And that is considered a request?

A request is generated every time that the end user writes a question in the chat bot? Or a request is equal to a session?

According to the price page, $0.007 per request.

For example:

  • A user opens a conversation with the chatbot
  • And ask 5 questions, with its 5 responses from the chatbot
    What price would it generate? $0.007 by one session or $0.007 by questions? $0.007 x 5 = $0,035

Thanks

    I’m voting to close this question because it's not about programming but rather about customer service. See [Why can't I ask customer service-related questions?](https://meta.stackoverflow.com/questions/255745/why-cant-i-ask-customer-service-related-questions). – Dada Aug 13 '21 at 08:12

As per the Pricing documentation, a request is defined as any call to the Dialogflow service. Note that a request is not equivalent to a session - a session may consist of multiple requests.

Moreover, also note that a new Dialogflow CX pricing model (2021-09) will take effect on September 1, 2021 - customers will be charged per request. Until that date, the original prices (2020-09) are in effect - customers are currently charged per session.

For your example, where the end-user asks 5 questions by sending text requests to a chatbot and receives 5 responses from the Dialogflow CX agent, this counts as 5 text requests, and the cost would be:

  • CX Agent (2020-09) (current): $20 per 100 chat sessions
    • If you have 5 requests that are sent by the same end-user, it is considered as 1 session only. Hence, the cost will be $0.20.
    • If you have 5 requests where each request is sent by different end-users, it is considered as 5 sessions. Hence, the cost will be $1.
  • CX Agent (2021-09) (starting September 1, 2021): $0.007 x 5 = $0.035

Basically, each time an end-user sends a query to the agent, the Dialogflow API’s detectIntent or StreamingDetectIntent method gets called and that counts as one text request or one audio request, depending on whether the application sends text or voice data to Dialogflow.

so for the most recent CX Agent (2021) you will pay $0.007 per request, so using your example if a user asks 5 questions thats 0.007*5 = $0.035.

If you're using a 2020 CX Agent you'd be paying $20 per 100 sessions, a session would be any conversation the agent would have with one user. So if your user asked 100 questions it would still be considered one session.
