I am trying to use 3.5 API but sometimes it down and i want use GPT4 API as a backup,
want to know when gpt 3.5 API is down at the same time is gpt 4 API down too?
Are you familiar with the OpenAI Status page?
You can subscribe to get updates in email, slack, rss, etc.
I have done some experimentation with the status page and you can sign up for webhook updates, they work well. You would then need to search the webhook text contents for the terms gpt-3.5-turbo and gpt-4, that would also be reliant on the ticket creator being consistent with the wording used, i have seen variation in that so that could be a problem.
Another way of doing it could be to have a periodic test subroutine calling GPT-3.5 with a test request and if that test request timed out, some kind of 3 tries conformation and then a subsequent test of the GPT-4 endpoint, that way you would know with, potentially, more accuracy, depending on how often you polled the GPT3.5 endpoint with your short test message.
