## Feature and Einstein Requests Usage

Einstein Requests is a usage metric for generative AI. The use of generative AI capabilities in either a production or sandbox environment consumes Einstein Requests and possibly Data 360 credits.

Subject line generation and body copy generation don't consume credits for AI Usage.

## Feature Limits

Your enterprise account has a lifetime limit of 10,000 inferences. Contact your Salesforce representative for additional inferences.
