Info about Request Calculation
Notice, that Salesforce measure your Einstein Generative Requests. Actually you will have 25,000 Requests per user/month within your Einstein License Subscription.
How much Requests you are using with one task for Einstein is calculated based on the following formular:
Einstein Input + Einstein Output (word count) / 1,500 = Number uprounded to next integer * Multiplier (depends on Model) = REQUEST COUNT
e.g. (2,000 + 500) / 1,500 = 2 * 10 = 20
