6 x 1000 token calls per day, for a news bot (listed use case at application).

I think what happened is the azure subscription was converted from a (multi year) promotional subsidy/discount to a full pay as you go subscription. No change to sub id. Payment methods OK. Everything else continued working, but openai gpt-4 access stopped the next day.

I’d rather use the Azure version because they promise 12-month sunsets vs OpenAI 6-month sunsets for model versions.

You should contact support and if you're up for it document how that goes.

Azure is mostly better for production: the developer experience is awful and the default filtering is more aggressive, but you get dedicated capacity by default which improves latency (something you need to negotiate with OpenAI's sales team for otherwise)
