## What credits pay for

Credits fund everything that calls an AI model: chatting with the assistant, generating questions, and building tests. Everything else, creating tests, grading, monitoring, taking tests, never touches your balance.

## Watching your balance

The **Usage** page has an **AI Credits** view showing a used-versus-remaining bar with exact figures on hover, total tokens in and out, and a filterable **Usage History** table listing each request with its model, token counts, and cost. A month picker narrows the window. The same balance is visible inside the AI panel while you chat.

## Topping up

Click **Get more** on the Usage page to buy additional credit through checkout. The new balance shows up as soon as the purchase completes.

## When you run out

AI requests stop with an explicit out-of-credits message in the panel until you top up. Nothing else about your organization changes.

## Model choice affects cost

Stronger models generally cost more per request. ExamLive picks the model for each request automatically and switches to a fallback when the primary model is rate-limited.
