OpenAI does not provide access to GPT-4 32K tokens model via API. Also they have weird restriction that you don't get access to even weaker GPT-4 model unless you had paid them at least 1$ before for API usage. They API prices are quite cheap, so I have to artificially generate lot of requests to them against GPT-3, so that I can pay them 1$, so that I get access to GPT-4. As far as I understand, this is the way to go currently.
