Service credits, what are they and how are they consumed?

[MichelMindsUnit]

Hello,

In the license guide for PowerApps+Flow the section about AI Builder mentions service credits.

We can purchase "units", each comes with "1 million service credits"

It's unclear to me what 1 service credit is exactly, can anyone clarify that?
And where can we see our current consumption of these credits?

This is what the guide says about it:

AI Builder capacity is expressed in the form of “service credits”. Service credits serve as the single (common) currency across all the scenarios supported by AI Builder. Available service credits are deducted when AI Builder services are used.
Different scenarios (for example, forms processing, prediction, etc.) burn down service credits at different rates.
Customers should purchase the appropriate number of AI Builder capacity add-on units based on anticipated usage across all scenarios.

It makes sense that the different models consume service credits at different rates (complexity, multi-page documents, what have you) but, without knowing what the value of each service credit is, it's very difficult to purchase the appropriate number of units.

Microsoft gives this example - giving me the hint that there is some kind of calculation that I'm unaware or:

Each unit of “AI Builder capacity add-on” includes 1 million service credits per month. For example, a customer requiring 4.7 million service credits per month (based on anticipated usage), should purchase 5 units of “AI Builder capacity add-on”.

Hope someone can shine some light onto what is 1 service credit, how is it measured and where can I see my current consumption/remaining credits?

- Michel
