The Kimi Code usage limit is not one number. Every plan that includes Kimi Code has a rolling five-hour window and a share of the Kimi membership's monthly total, and members on the older plans also have a seven-day window, so the first job after a 429 error is to find out which of these ran out.
UsageAtlas, a free and open-source desktop tracker, can show the windows Kimi reports for your account next to your other coding tools, with a reset time on each one when Kimi supplies it.
The windows behind the Kimi Code usage limit
Moonshot's membership guide splits subscribers into two groups. The current plans are Go, Plus, Pro, Max and Ultra; Go carries no coding quota, so Kimi Code starts at Plus. The legacy plans keep their old names and rules.
| Window | Current plans (Plus and up) | Legacy plans |
|---|---|---|
| Rolling five hours | Yes | Yes |
| Seven days, counted from your subscription date | No | Yes |
| Monthly membership total | Yes | Yes |
The monthly total is the one people forget. It is shared with every other Kimi membership benefit, PPT and Agent Cluster included, and when it is spent Kimi Code stops even if its own shorter window still shows room.
What counts toward it
Everything you send through your membership counts: the Kimi Code CLI, the VS Code extension, the desktop app and third-party clients pointed at the Kimi Code API. All logged-in devices and every API key draw from the same pool, so a second key does not add capacity.
Model access is a separate matter. A 403 error saying your subscription lacks a model or a 1M context window is about plan tier, not about how much you have used.
Reading the error
The error reference names each limit in the message itself: five-hour, weekly (7-day) or monthly. For those three, retrying is pointless. You wait for the window to roll over, buy Extra Usage, or move to a bigger plan.
Two other 429 messages look similar but are short-lived. "We're receiving too many requests" and "The engine is currently overloaded" clear after a brief wait and have nothing to do with your quota. If you use Kimi Code through Claude Code or OpenCode, the client may rewrite the error code, so go by the wording.
Watching the limit before it hits
Kimi's own views are the Kimi Code Console and the /usage command in the CLI. They are the source of truth for your account.
UsageAtlas adds a running view on your desktop. You paste a Kimi Code Coding API key, pick the Global or China region, and the Limits screen lists the five-hour, seven-day or monthly windows your account returns, each with its remaining share and reset time. You can set a remaining-capacity threshold on a window and get one alert per reset cycle. It runs on Windows, macOS and Linux, needs no account for local tracking, and does not read your prompts.
Be clear about the scope: the Kimi connection reads current allowances only. It does not import per-request tokens, model history or cost history for Kimi, and a window Kimi does not report shows as unknown rather than zero. If you want per-request detail, the Console is still where to look.
FAQ
Does every Kimi Code plan have a weekly limit? No. Moonshot removed the weekly window for members on the current plans. Only legacy plans keep the seven-day refresh.
Why did Kimi Code stop when the Console showed quota left? The monthly membership total is shared with other Kimi features. If that total is used up, Kimi Code freezes until the next billing cycle or an upgrade.
Can I keep working after hitting the limit? Yes, if you are subscribed and turn on Extra Usage. It is deducted only after your plan quota, and you can set a monthly spending cap.
