Hello @Harris Jay
Thanks for reaching out to us. I think you are mentioning the legacy tier S1 - S5.
Fixed tiers are only available to legacy (Marketplace) Azure AI Health Bot instances. These tiers charge a set recurring amount and include a fixed volume of messages that can be consumed in each calendar month. The message count for your bot resets on the first of each month.
With fixed tiers, you can't exceed the fixed fee or the included message volume. The Owner of the Azure AI Health Bot resource receives a notification at 80% and 100% consumption of the message limit for the tier. On fixed tiers, you can upgrade to a higher tier at any time to increase your message limit.
Messages are counted for each side of the communication. This means that a single back-and-forth interaction of a user with the bot, where a user says something and the bot answers, accounts for two messages: one message from the user to the bot, and one message from the bot to the user.
To select the best, fixed tier plan, you'll need to estimate the number of messages you expect your bot to have per month. This is based on the number of users that you expect will visit your site and the average length of the conversations you anticipate (based on the scenarios you have designed).
Throughout the month you can check the current consumption through the usage counter in the management portal and see usage from previous months in the built-in telemetry and analytics reports available in Azure AI Health Bot
Typically, customers use lower quota plans in the earlier stages of bot development phase and upgrade as they go into real-world testing and production.I hope this helps.

Yutong
