Nice to see they are working on reducing the pricing. GPT-4 is just too expensive right now imo. A long conversation would quickly end up costing tens of dollars if not more, so less expensive model costs + stateful API is urgently needed. I think even OpenAI will actually gain a lot by reducing the pricing, right now I wouldn't be surprised if many uses of GPT-4 weren't viable just because of the costs.
Dozens of people using it daily for coding and conversations and review in a month might be a couple hundred bucks. All day convo, constantly, as fast as it can respond, might add up to $5.
Not sure what kind of convo you're having that you could hit $10 unless you're parallelizing with something like the "guidance" tool or langchain.
