## The ladder

|                 | **Free** | **Core** | **Pro** | **Max**  |
| --------------- | -------- | -------- | ------- | -------- |
| Price           | —        | \$15/mo  | \$49/mo | \$149/mo |
| Credits / month | 30 once  | 900      | 3,500   | 9,500    |
| 5-hour window   | 30       | 120      | 350     | 850      |
| Weekly          | 30       | 350      | 1,100   | 3,000    |
| Economy models  | ✓        | ✓        | ✓       | ✓        |
| Standard models | —        | ✓        | ✓       | ✓        |
| Premium models  | —        | —        | packs   | ✓        |

**Free** is a one-time 30-credit trial on economy models — enough for two or
three real tasks.

**Core** runs economy models full-time with Sonnet 5 available and metered.

**Pro** is the same access with roughly 4× the budget, plus pay-as-you-go packs
for premium models.

**Max** includes Kimi K3, Opus 4.8, and Fable 5 in the monthly pool, with the
highest windows.

See [Models](/models) for what's in each tier.

## BYOK

\$10/mo flat with your own OpenRouter key. No credits, no plan locks, no metering
— you pay OpenRouter directly and we never see the key. See
[Authentication](/authentication).

## Limits

Two rolling windows apply at once:

* **5-hour window** — the session budget, the one you'll actually feel
* **Weekly** — a rolling 7-day ceiling

Hitting either pauses work until it rolls off, or until you buy a
[reset](/credits#session-resets).

## Choosing

<AccordionGroup>
  <Accordion title="Which plan fits my usage?">
    Most work routes to economy models under [Auto](/models), where credits go a
    long way. Core suits a few focused sessions a week; Pro suits daily use; Max
    suits all-day use or frequent frontier-model work.
  </Accordion>

  <Accordion title="Why do credits drain fast on strong models?">
    Because 1 credit = $0.01 of *raw* model cost. A heavy session costs about
            $0.51 on GLM 4.7 Flash and about \$11.80 on Sonnet 5 — a \~23× spread. That's
    the entire reason Auto exists. See [Credits](/credits).
  </Accordion>

  <Accordion title="What happens when I run out?">
    9p tells you which limit you hit and when it resets, and offers a reset
    purchase where your plan allows one.
