What to do if Cerebras Inference is not working

  1. Check the status card at the top of this page. If Cerebras Inference reports an incident, the errors are on their side.
  2. Retry failed requests with exponential backoff (for example 1, 2, 4, 8 seconds, with some random jitter). Short 500, 502, 503 and 529 errors often clear within minutes.
  3. A 429 error means a rate limit or quota, not an outage: check your usage limits and tier, and slow down or batch requests.
  4. A 401 or 403 error usually means the API key is wrong, revoked or out of credit: check the key and your billing page.
  5. Check the model name: retired or renamed models return errors that look like an outage.
  6. Keep a fallback: route to another provider or model while Cerebras Inference is down (see the alternatives below), or use a router that switches automatically.

Cerebras Inference outage questions

Is Cerebras Inference down right now?

The card at the top of this page reads Cerebras Inference's official status page live, and times Cerebras Inference's API from our servers every few minutes. If the official page shows an incident, the problem is on Cerebras Inference's side.

When was Cerebras Inference last down?

We have not recorded a Cerebras Inference outage or degraded period since we started tracking it on Oct 7, 2026. Its uptime and the full history are on the Cerebras Inference outage history page.

Why does Cerebras Inference return 500, 502 or 503 errors?

These are server-side errors: the request reached Cerebras Inference but it could not answer. They usually come in bursts during incidents or heavy load. Retry with exponential backoff, and check the status above.

What does a 429 error from Cerebras Inference mean?

429 means too many requests: you hit a rate limit or a usage quota. It is not an outage. Slow down, batch requests, or raise your limit in your Cerebras Inference account.
