How credits work
A credit is not a reply. The model your agent uses sets the cost of each reply.
1. Credits come with your plan. Each plan includes a monthly number of credits.
2. Each reply uses credits. Lighter models use fewer credits per reply than larger ones.
3. You choose the model. Set it per agent.
4. Watch usage live. Credits, storage and crawls are tracked. Go to Account › Settings › Usage.

Note: Extra credit packs expire at the end of your billing cycle.
