There's a lot of theories floating out there that OpenAI will make gpt-4-turbo free (or at least free when used via custom GPTs) so the default won't have to be 3.5-turbo (which is terrible at following system prompts and pales in quality compared to 4/turbo).

I assume they want to do it but can't until they know the higher cost of the larger model works for their bottom line in that way and that they have are consistently getting enough inference compute to support that. It would probably be a very large jump in compute usage.
