# Usage and limits

Nock's hosted services have usage limits. When enabled for your account, the Usage panel shows the percentage of an allowance consumed and any available reset information.

## Understand the meters

Different access modes can show different windows, including a five-hour window, a week, a rolling month, or a total trial allowance. A percentage is a share of that allowance; it is not a dollar balance or a count of messages remaining.

A longer task can use more than a short conversation. Cloud transcription, spoken replies, model work, and available connected tools can involve different services. Avoid estimating remaining work from message count alone.

## When a limit is reached

Read the message attached to the exhausted allowance. If a reset time is shown, wait until that window opens again. If trial usage is exhausted, the account may remain paused until the subscription starts according to the checkout terms.

On-device dictation is distinct from hosted agent usage. Check which feature is locked rather than treating a hosted limit as a failure of every part of Nock.

## Usage cannot be checked

A temporary service problem can prevent Nock from safely checking or recording hosted usage. In that case, a request may stop before work begins. Wait briefly and try again; do not launch many duplicate requests to force it through.

If a task might already have performed an external action, inspect the destination before retrying. This avoids creating duplicate messages or records.

## Background workers

Concurrent-worker limits control how many background tasks can run at once. They are separate from usage allowances. If you cannot start another worker, review existing tasks and your account's enabled limits.
