# Limits & quotas

> Codiv is a free public experiment. Limits keep the shared GPU fast for everyone.

## Token quota

Every account gets **100M free input tokens**. Output tokens are always 0 and are not counted. Usage is shown on the [dashboard](https://codiv.ai/dashboard). When the quota is used up, requests return `429` with `error_type: "quota_exceeded_error"`. Requests already in flight at that moment still complete. Paid plans with larger quotas are coming soon.

## Rate limits

| Limit | Value | When exceeded |
|---|---|---|
| Requests per key | 1,200 per minute (default) | `429 rate_limit_error` |
| Active keys per account | 10 | Key creation is refused |
| Server capacity | Shared | `529 overloaded_error` with `retry-after` |

## Request limits

- Context window: 65,536 tokens. The state and questions are read together, so keep the state a little under that (about 60,000 tokens leaves room for a large question set).
- Request body: 512 KB.
- choice: up to 128 options. score: 2 to 10 levels.
- Questions per request: no fixed limit. Large sets are answered in parallel chunks.

## Retries

Retry `429 rate_limit_error` and `529` with exponential backoff, and honour `retry-after` when it is present. The TypeSafe SDKs do this for you. Do not retry `quota_exceeded_error`.
