You get $5 in credit, automatically put onto your account. Each time you use an AI task, it deducts from this credit. This is because these cost Botpress money from OpenAI, but Botpress is not putting a markup on these like many companies do, they are simply charging you what it costs them. It is calculated based on tokens and how big each AI task is, but you will be able to do tens of thousands of tasks with this $5 worth of credit.
