Have you had trouble finding the GPT-4 Mini API in the selection options? It seems that only the previous models are showing up when attempting to select an API. Could this be due to the newness of the GPT-4 Mini? Additionally, are there any updates on the GPT-4.5 model?
Lastlly, can you provide information on accessing the GPT-4 Preview 32K? I keep encountering messages indicating that I do not have access to it.
