Kimi AI Not Working? How to Check Its Status and Fix Common Problems

Last checked: October 13, 2026. At the time of checking, Moonshot AI’s official status page reported that Kimi’s website, sign-in system, file uploads, search, models, Kimi Code, and API services were operational. Service conditions can change, so check the live status before changing your browser or reinstalling an app.

If Kimi AI is not working, begin by checking the official Moonshot AI status page. If no incident is listed, try a new conversation, reopen Kimi, and test another browser or network. These checks quickly show whether the problem is service-wide or limited to your account, conversation, device, app, browser, or internet connection.

Do not clear all browser data, reset your device, or reinstall Kimi as your first step. Preserve any unsent prompt or important local work before using a fix that could sign you out or remove app data.

Is Kimi down, or is the problem on your device?

The official status page is the fastest way to separate a Kimi outage from a local problem. It tracks individual components, including the website, sign-in and sign-up, file uploads, search, models, Kimi Code, the Open API, and the Open Platform portal.

Open the Moonshot AI status page.
Look for an incident affecting the component you are using. A file-upload incident, for example, does not necessarily mean normal chat is unavailable.
If an outage or degraded-performance notice is active, avoid repeatedly signing out, clearing data, or reinstalling the app. Wait for the incident to be resolved and monitor the status page.
If all relevant components are operational, use the tests below to isolate the problem.

What the test results usually mean

Kimi works in a private browser window: an extension, cookie, or saved site setting in your normal browser profile is probably interfering.
Kimi works on mobile data but not Wi-Fi: the Wi-Fi network, DNS service, firewall, proxy, or content filter is the likely source.
Kimi works in a new chat but not an old one: the original conversation may be too long or stuck on a specific tool request.
The website works but the app does not: focus on updating or repairing the app rather than changing your account.
Kimi fails on every device and network while the status page reports an incident: the problem is probably service-side, so local troubleshooting is unlikely to help.
Only one account is affected: check login, verification, usage, or account-status issues.

Try these quick fixes first

Follow these steps in order. Test Kimi after each one so you know which change fixed the problem.

Check the official status page. Stop local troubleshooting if the affected component has an active incident.
Save your unsent prompt. Copy it to a temporary document before refreshing, closing the app, or signing out.
Start a new conversation. If the new chat works, the problem is probably limited to the original conversation or its accumulated context.
Refresh the page or fully close and reopen the app. Do not submit the same request repeatedly while the first attempt may still be processing.
Try a private window or another current browser. This helps identify extension, cookie, and profile problems without immediately deleting saved data.
Switch between Wi-Fi and mobile data. If only one network fails, troubleshoot that network rather than reinstalling Kimi.
Update Kimi and your browser. Use the official Kimi download page or the official store reached from it.
Sign out and back in only if necessary. Confirm that you can access your sign-in method before ending the current session.

Find the right fix for your symptom

Symptom	Likely problem area	Best first action
The site or app fails for everyone during a listed incident	Kimi service	Wait and monitor the official status page
The website is blank or keeps loading	Browser, extension, saved site data, or network	Try a private window and another network
A message will not send or shows a red circle	Sending-frequency restriction or unstable connection	Preserve the prompt, check the network, and follow the waiting guidance below
Kimi says it is “a little tired”	Temporary capacity pressure	Wait briefly, then retry once
Only one long conversation fails	Conversation context	Create a handoff summary and continue in a new chat
An SMS verification code does not arrive	Phone number, supported region, or delivery delay	Verify the number, wait at least five minutes, then resend once
File upload fails	Upload service, file size, browser, or conversation	Check file-upload status and test a smaller file in a new chat
The app crashes but the web version works	App installation or device	Update the app and use the web version temporarily
Only Kimi Code or the API fails	Developer service, credentials, balance, rate limit, or configuration	Use the developer status component and official error documentation

Kimi website is not loading or shows a blank page

If the official Kimi website will not open but the status page reports the website as operational, test the browser before changing your account.

Confirm the address. Open Kimi from kimi.com rather than an unofficial login, download, or mirror site.
Reload the page once. If it remains blank, close the tab and open Kimi again.
Open Kimi in a private or incognito window. If it works there, return to your normal browser and test extensions individually.
Temporarily disable optional blockers for Kimi. Ad blockers, script blockers, privacy extensions, and strict browser protections can interfere with interactive websites. Disable them only for the test, then restore anything that was not responsible.
Remove only Kimi’s saved site data. Search your browser’s privacy or site-settings page for kimi.com and remove that site’s cookies and stored data instead of deleting your entire browser history.
Try another updated browser. If Kimi works there, the problem is limited to the original browser profile.
Test another trusted network. Disable an optional VPN, proxy, Private DNS service, or network filter temporarily to diagnose the connection. Do not use these tools to bypass regional, legal, or account restrictions.

Before clearing site data: copy unsent prompts and confirm that you can sign in again. Removing site data normally ends the current browser session and may remove unsent local state.

Kimi app keeps crashing, freezing, or refusing to open

Kimi’s official download center provides mobile downloads for iOS, Android, and HarmonyOS, along with desktop options for Windows and macOS. Use that page to reach the correct installer or app-store listing; do not install an unofficial APK or third-party desktop package.

Test the web version. Open Kimi in a browser. If it works, your account and the main Kimi service are probably available.
Force-close the app and reopen it. Make sure it is fully closed rather than left suspended in the background.
Update the app. Follow the link for your platform from the official download center.
Restart the device. This can clear a stuck app process without removing data.
Check available storage. Free some space if the operating system reports that the device is almost full.
On Android, clear the app cache first. The menu is usually under Settings → Apps → Kimi → Storage, although labels vary by manufacturer. Do not select “Clear storage” or “Clear data” yet.
Reinstall only as a last resort. Confirm your login method and preserve important local work first.

Normal Chat conversations can sync across Kimi’s web, mobile, and desktop experiences when you use the same account. However, Kimi’s official download page states that Work mode conversations remain on the desktop where they were created. Preserve any important local Work mode material before removing or reinstalling the desktop app.

Kimi messages will not send or a red circle appears

Kimi’s official Chat FAQ identifies two main causes for this symptom: a sending-frequency limit and poor network conditions. Its current guidance says to wait two to three hours if frequent messages triggered the limit, or switch networks if the connection is weak or unstable.

Copy the unsent message so you do not lose it.
Check the official status page for website, model, or sign-in incidents.
Open another website to confirm that your connection is working.
If the network is unstable, switch between Wi-Fi and mobile data.
If you have sent many messages in a short period, stop retrying and follow Kimi’s waiting guidance.
After the waiting period, send the message once in a new conversation.
If only a large prompt fails, shorten it or divide it into smaller requests.

Repeatedly pressing Send is unlikely to help a frequency restriction and can make it harder to tell whether the connection has recovered.

Kimi is slow, stuck, or not responding

If Kimi says it is “a little tired”

The official Help Center describes this message as temporary peak-hour capacity pressure. Its current recommendation is to wait one to two minutes and try again. Check the model component on the status page if the message continues.

If there is no specific error message

Check whether the same request works in a new conversation.
Reduce a very large task into smaller, clearly defined stages.
If the request includes several files, retry with one file at a time.
Test a simpler text-only prompt. If that works, the issue may be limited to a tool, file, or complex workflow rather than normal chat.
Try another network or device to separate account behavior from local performance.
If every new conversation stalls while the status page remains operational, submit a technical report to Kimi Support.

Only one long conversation is not working

A conversation can stop accepting useful new context after it becomes very long. Kimi’s official guidance recommends splitting an oversized file, summarizing the important conclusions from a long conversation, and continuing from that summary in a new chat. Deleting earlier messages in the same conversation does not free the existing context window.

If the conversation still responds, ask Kimi to create a concise handoff containing the goal, important facts, decisions, unfinished tasks, and relevant constraints.
Copy that handoff into a new conversation.
Attach only the files needed for the next stage.
Split a very large document into logical sections rather than uploading the same oversized file repeatedly.
Keep the original conversation until you have confirmed that the new one contains everything important.

If a new conversation works immediately, do not clear the entire app or browser. The original chat—not your installation—is the more likely problem.

Kimi login is not working or the verification code does not arrive

First check the “Sign In / Sign Up” component on the official status page. If it is operational and you are waiting for an SMS code, follow Kimi’s current verification guidance.

Confirm that the mobile number and country code are correct.
Wait a few minutes for delayed SMS delivery.
If more than five minutes have passed, request one new code.
Do not repeatedly request codes in rapid succession.
Make sure you are using a mobile number from a supported region. Kimi’s Help Center states that VoIP numbers and landlines are not supported for this process.
Never share the verification code with another person, a public forum, or a website offering temporary SMS numbers.

If the phone number attached to your account is no longer active, use Kimi’s official mobile-number support instructions. Do not create a new account until you understand whether your existing conversations or membership are tied to the old account.

If Kimi displays an account-suspension notice, normal browser troubleshooting will not restore access. Follow the official account appeal process instead of attempting to bypass the restriction.

Kimi file upload or download is not working

If a file will not upload

Check the “File uploads” component on the official status page.
Create a new conversation and test one smaller file.
If the smaller file works, split the original document into logical sections.
Use a short filename without unusual symbols and retry from another updated browser.
Check whether a browser extension or network filter is blocking the upload.
If every file fails across different browsers and networks, report the issue with the file type and approximate size—but do not send a confidential file unless official support specifically requires it through a secure channel.

If the failing file is a PDF, use our Kimi PDF upload and verification guide for document-specific checks.

If a generated Office file will not download

Confirm that you are using the correct Kimi feature. According to Kimi’s current Chat FAQ, the normal chat window does not directly create downloadable Office files. Use the PPT Assistant for downloadable presentations and Agent for Word or Excel output.

Open the generated item from the feature that created it.
Allow downloads from kimi.com if your browser blocked them.
Test the download in another browser.
If a file downloads but will not open, generate it again and check whether the new copy has a normal file size.
Use the relevant Kimi feature’s Help Center page if the issue is limited to PPT, Docs, Sheets, Build, or another tool.

Clear browser or app data only as a last resort

Warning: clearing site data, clearing app storage, signing out, or reinstalling can end your session and remove unsent local information. Confirm your login method and copy important prompts before continuing.

For the website

Remove cookies and stored data for kimi.com only.
Reopen the website and sign in again.
Test a new conversation before restoring browser extensions.

For the mobile or desktop app

Update the app first.
On Android, try clearing cache before clearing app storage.
Use the web version to confirm that your account still works.
Preserve local Work mode content before removing the desktop app.
Reinstall only from the official Kimi download page or the store linked from it.

A full network reset is rarely necessary for a Kimi-only problem. Consider it only when multiple unrelated apps and websites also fail, and review what the reset will remove before proceeding.

Kimi Code or the Kimi API is not working

Consumer chat, Kimi Code, and the Kimi API are separate products with different error paths. Do not reset an API key or change development settings because the consumer website is slow.

Check the Kimi Code, Open API, and Open Platform components on the official status page.
For Kimi Code, use the official Kimi Code documentation, including its error reference and desktop troubleshooting pages.
For API requests, use the official Kimi API Help Center to identify authentication, insufficient-balance, rate-limit, model, and request errors.
Compare the returned HTTP status and error body with the official error reference instead of guessing from the symptom.
Confirm that the key, endpoint, model ID, account balance, and current rate limit belong to the same platform account.
Never publish an API key, authorization header, or full request log containing credentials.

For installation, authentication, and client checks, use our Kimi Code setup and troubleshooting guide.

For endpoint, account, and request checks, see our Kimi API setup and error checks guide.

The API Help Center currently provides separate references for API errors, 401 authentication failures, 403 insufficient-balance errors, 429 rate limits, usage lookup, and throughput limits. Kimi Code also has dedicated documentation for desktop, CLI, IDE integrations, error messages, and support.

For API-specific support, sign in to the Kimi Open Platform and use the support details shown for your developer account.

When to contact Kimi Support

Contact support when the official status page is operational but the problem continues across a new conversation, another browser or device, and another trusted network. You should also contact support for account access, an inactive bound phone number, suspected account restrictions, or a repeatable product bug.

Kimi provides in-product feedback and email support for general technical issues. On the web, the official path is Account → User Feedback → Help & Feedback. In the mobile app, use Account → Settings → Feedback. General technical questions can also be sent privately to [email protected].

Include the following information so support can reproduce the issue:

The exact error message or visible symptom.
The affected feature, such as chat, search, file upload, login, Kimi Code, or the API.
The approximate time of the problem and your time zone.
Your device and operating-system version.
Your browser or Kimi app version.
Whether the problem occurs on another device or network.
Whether a new conversation works.
A screenshot with private documents, verification codes, payment details, and unrelated personal information hidden.
Your registered email address or mobile number only when communicating through Kimi’s official private support channel.

Never post passwords, SMS codes, API keys, private uploaded documents, or full account details in a public forum or GitHub issue.

Frequently asked questions

Is Kimi AI down right now?

At the time of checking on October 13, 2026, Moonshot AI’s official status page showed all Kimi systems as operational and listed no incident for that date. Check the live status page because the result may have changed since this article was reviewed.

Why does Kimi work on mobile data but not Wi-Fi?

This result points to the Wi-Fi network rather than the Kimi app. Temporarily test without an optional VPN, proxy, Private DNS service, firewall rule, or content filter. Restarting the router may help if other websites are also unstable. Do not reinstall Kimi repeatedly when it already works on another network.

Why does Kimi work in a new chat but not my old conversation?

The old conversation may have accumulated too much context or become stuck on a specific request. Preserve its key information in a summary, start a new chat, and continue from the summary. Removing earlier messages from the same conversation does not reset its accumulated context.

Will reinstalling Kimi delete my conversations?

Chat-mode conversations can sync across supported Kimi devices when you sign in with the same account. Kimi’s official documentation says Work mode conversations remain on the desktop where they were created, so preserve important local Work mode material before reinstalling the desktop application.

Should I install an APK from another website if Kimi is unavailable in my app store?

No. Use Kimi in the browser or follow the platform links on the official download page. An unofficial installer may be outdated, modified, or designed to collect login information.

What should I do if none of the fixes work?

Confirm that the relevant service component is operational, reproduce the problem in a new conversation, and test another browser, device, and network. Then submit a report through Kimi’s official support channels with the exact error, time, platform details, and a redacted screenshot.
