9th Protocol is in private beta. These numbers are being calibrated against real
usage and may change before general availability.
The ladder
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 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.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
Choosing
Which plan fits my usage?
Which plan fits my usage?
Most work routes to economy models under Auto, 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.
Why do credits drain fast on strong models?
Why do credits drain fast on strong models?
Because 1 credit = 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.

9p tells you which limit you hit and when it resets, and offers a reset
purchase where your plan allows one.
