Using the chat-gpt-3.5 API we have run some tests that we are very anxious to try on GPT-4 API to see if it would do better and by how much. Alas for our previous uses of GPT-3.5 API charges fell a little short of $1.00 (despite hundreds/thousands of API calls), and we apparently didn’t make the cut and don’t have access to GPT-4 API. When might GPT-4 API become available to paying customers like us?
No one knows. You can try reading other posts on this. I dont think the developers even know!
