# Plans and quotas

> Guest, Free, Go, Plus, and Pro as listed in Settings → Plan & billing. Quotas fail closed and tell you when they reset.

Your plan, today's usage, and the reset timers live under **Settings → Plan & billing**. The product is the source of truth for numbers; this page explains what each plan is for and how limits behave.

## The plans

| Plan      | Price        | Who it is for             | Includes                                                                                                                                                                   |

**Plus** is the recommended plan in the product. Switching takes effect at the next billing cycle. At the time of writing the **Get Free / Go / Plus / Pro** buttons and **Billing history** are marked **Coming soon**; the ladder above is what the product lists.

## Usage and reset timers

**Settings → Plan & billing** shows today's and this month's message counts with a reset countdown for each window.

## How limits fail

Cortex quotas **fail closed**: when a window is used up, the product says so and tells you when it resets. Nothing is silently downgraded, and there is no paywall pretending to be a quota.

| What happened                                   | Error code                                               | What to do                                                                      |
| ----------------------------------------------- | -------------------------------------------------------- | ------------------------------------------------------------------------------- |
| You used the window for today or this month     | [`quota_exceeded`](/problems/quota_exceeded)             | Wait for the reset shown in the product, or move to a plan with higher ceilings |
| The plan does not include the capability at all | [`entitlement_required`](/problems/entitlement_required) | That capability is not on this plan                                             |
| Too many requests in a short burst              | [`rate_limited`](/problems/rate_limited)                 | Retry after the pause the product suggests                                      |
| The fleet is at capacity                        | [`no_capacity`](/problems/no_capacity)                   | Try again shortly; Go and above get priority when the fleet is busy             |

Image generation on Free and Guest is metered as `images_per_day`. Running out is `quota_exceeded`, not a paywall. See [Image generation](/chat/images).

The CLI shows the same thing in the terminal: when the agent quota is exhausted the composer is held with the reset time, and `/usage` shows the details. See [CLI troubleshooting](/cli/troubleshooting).

## Model availability

Model availability depends on your plan. During peak hours new chats may fall back to a faster model; the composer chip always shows which model is serving the conversation. See [Models](/chat/models).

## Frequently asked

<AccordionGroup>
  <Accordion title="Do guest messages and Free messages share a quota?">
    No. The guest allowance belongs to the browser session and ends when you sign in. Free has its own daily and monthly limits on the account.
  </Accordion>

  <Accordion title="Does unused quota roll over?">
    No. Daily and monthly windows reset on the timers shown in Plan & billing.
  </Accordion>

  <Accordion title="Was there a Pro trial?">
    Through 7 September 2026 a signed-in member could claim one month of Cortex Pro from the product. That window has closed; claiming twice never stacked.
