How are Credits Calculated?

Credits are based on 2 things: Messages sent & Tools Called.

Messages Sent: Credits are used just for messages you send, not ones that Miyagi sends.


Tools Called: 
A smaller percentage of credits will be used for every tool called. For example, when you ask Miyagi to write alt text, Miyagi calls a tool to do this. Each time it writes alt text for an image, it will be calling a tool to do that. Larger bulk tasks will require more credits them simple ones.


Credits vary by model, which are shown below:
