# AI credits

AI credits are used when AI generates an answer.

AI credits are used when your AI agents consume LLM models to generate a response. The action blocks that consume AI credits are:

* Answer AI 
* Set AI  
* AI Agent

## How AI Credits are calculated

AI credits are charged based on the number of tokens used in each response. Every model has a defined credit rate per 1,000 tokens consumed.

Tokens include all text processed in a single interaction — the input (your prompt and conversation history) and the output (the AI's response) combined.

For example, if a model charges 1 credits per 1,000 tokens:

* A response using 1,000 tokens = 1 AI credits
* A response using 3,000 tokens = 3 AI credits
* A response using 10,000 tokens = 10 AI credits

This means shorter responses use fewer credits, and longer or more complex responses use more. You only pay for what you actually use.

## Extra credits

If you exhaust your AI credits, you will be billed **$5 / 1,000 extra AI credits**.&#x20;
