I am finding that, for my uses, 4o-2024-08-06 is much less useful than 4o-2024-05-13. Do we know until what date either of these will be viable? I’m asking because on the one hand there’s such a short time between them that I would expect both to remain alive roughly for the same time. On the other hand, at least on Azure, the later model is for half the price, which makes me feel that OpenAI will prefer that we use that one. Are there any official announcements regarding this?
