Response time by location
Over the last 7 days, from the checks that passed: the time from the start of the request to the answer's headers, with the DNS lookup, the connection and TLS included.

What is checked
The API behind GPT models, used by apps that call a language model, generate images or transcribe audio.
StatOSS sends GET https://api.openai.com/v1/models and counts the check as passed on status 401 within 10 seconds. The API's list of models, on api.openai.com, where requests to the models go too. Without a key it answers 401.
An answer to an unauthenticated request says the API is reachable, not that models answer or how fast. ChatGPT is a separate product.
OpenAI API reports its own incidents at status.openai.com. The figures here are measured from outside and can differ from it in both directions.
How it is measured
- One check every 5 minutes, from one location at a time in turn: Aarhus and Copenhagen in Denmark, Falkenstein in Germany, Ashburn in the USA, Singapore, and Sydney in Australia.
- A check fails when no answer comes within 10 seconds, when the connection or TLS fails, or when the answer is not status 401.
- A failed check is repeated at once from a second location, and counts only when that location fails too, or cannot answer within 20 seconds.
- Two failed checks in a row make an outage, dated from the second, and the first check that passes ends it. A failure shorter than 10 minutes may not make one, and times are good to about 5 minutes.
- Availability is the share of checks that passed. There are no maintenance windows: every check counts.
It is the same check a StatOSS status page runs for its owner, with the same rules; the docs on checks have the details.
