# Billing Rules (Training & Conversations)

Both training and conversations consume credits, with the amount determined by the complexity of the operation.

| Operation | Credit Cost | Notes |
| --- | --- | --- |
| **Agent Training** | Ranges from tens to hundreds of credits | Depends on content & file complexity |
| **Regular Chat** | Based on message complexity | Simple Q&A costs less |
| **Complex Tasks** | Higher cost | Involves multi-step planning |

Tip: When friends use your trained agent, credits are charged to their account, not yours.
