What if I develop a chatbot related to technology using Gemini API, how much is the limits for free tier?

Hello, I wanted to develop a chatbot using Gemini API, I have currently developed a basic chatbot but the thing is that I want to know, how many users or message will my chatbot be able to handle, I read documentation but was unable to understand, how many messages or conversations per day is allowed? Also if I do keyword filtering, and the user ask something non related to key word any my chatbot just reply with ask something else, will it still be considered as a request and will decrease my limits? Thanks and also I am currently using gemini-1.5-flash, is it the only one I can use in free tier?

You can check the free tier here:

It changes between models.

Welcome to the forum

This really depends on where the keyword filtering occurs. If your code handles it, there has been no API request to the Google LLM and your quota isn’t affected. If you use an LLM to decide whether to handle the inquiry or not, that’s an API request and counts against your quota.

Hope that helps.
