Is AI21 Down Right Now?
No major AI21 outage is being reported right now. The AI21 status on this page tracks live reports from developers and Studio users. Most problems turn out to be API errors, rate limits, or a slow model response rather than a full AI21 down event. Check the report graph above. A sharp rise in reports usually matches a real incident on the platform.
AI21 Labs runs the Jamba model family and the AI21 Studio for testing prompts. The API and the Studio can fail in different ways at the same time. Your app can break while the Studio page loads fine. Always note which part failed before you start changing code.
Is AI21 Down for Me or Everyone?
To test if AI21 is down for me or everyone, send one small API request with a fresh key. If it returns a clean answer, your app config is the problem. If it times out or returns a 5xx error, the platform side is likely at fault. Trying the Studio playground gives the same clue. A failure in both places points to a wider issue.
Rate Limits That Look Like an Outage
Many AI21 down reports are really rate limit errors. Trial and lower tier keys allow only a small number of requests per minute. When your app crosses the limit, the API returns 429 errors and requests seem dead. Space out your calls, add retry logic with delays, and cache answers you reuse. A sudden traffic spike in your own app can trigger this without any platform fault.
Slow or Empty Model Responses
Long prompts and large output settings make Jamba answers slow. During busy periods, queues grow and answers can time out. Shorten the prompt, lower the max token count, and test again with a small request. If small requests also hang, note the time and check the reports on this page. Regional network trouble between you and the API can add delay too.
Studio Login and Playground Problems
The Studio sometimes fails to load after a browser update or with strict tracking blockers. Sign-in loops often come from blocked cookies. Try a private window, allow cookies for the site, and sign in again. If the playground loads but runs fail, the issue sits with the API, not your browser. Keep the exact error text, because it speeds up any support ticket.
Common AI21 Problems and Fixes
API returns a 429 error
You passed the request limit for your key tier. Slow down your calls and add retries with a growing delay. Spread large jobs over more time. If limits block real work, move to a higher tier in your account settings.
API returns a 5xx error
A 5xx code points to the server side. Wait a few minutes and retry the same request. Keep your request ID and the time of the failure. If errors continue for an hour, report the problem here and contact support with those details.
Studio page will not load
Clear your browser cache and cookies for the site, then sign in again. Turn off strict tracking protection for the page or try a private window. Test a second browser to rule out a local extension problem.
Answers come back empty or cut off
Raise the max tokens setting so the model can finish its answer. Check that your code reads the full response body, not just the first chunk. Short test prompts help you find whether size is the cause.
My API key stopped working
Keys can be revoked, expired, or tied to a closed trial. Create a fresh key in the Studio and update your app config. Never share keys in public code, because leaked keys get disabled fast. Store the new key in an environment variable.

Frequently Asked Questions
Why does the AI21 API return 429 errors?
Your key passed its rate limit for requests per minute. Trial keys have low limits. Slow your calls, add retry delays, and spread big jobs out. A higher tier raises the limit.
How do I check if AI21 is down?
Send a tiny test request with your key and try the Studio playground. If both fail with server errors, the platform likely has an incident. The live reports on this page show if others see the same failure.
Why are Jamba model responses so slow?
Long prompts, large output limits, and busy queues all add delay. Shorten your prompt and lower max tokens for a test. If even small requests hang, the slowdown is on the platform side.
What happened to the Jurassic models on AI21?
AI21 retired its older Jurassic line and moved users to the Jamba family. Old model names in your code can return errors after the change. Update your requests to a current Jamba model name.
Why can I not sign in to AI21 Studio?
Blocked cookies and stale sessions cause most sign-in loops. Allow cookies for the site, clear the old session, and sign in again. A private browser window is a quick way to test this.
Does AI21 API have a status page for incidents?
Yes, AI21 posts incident notes for major API problems. Minor slowdowns may not appear there. User reports on this page often surface small regional issues before any official note.
