It's only really useful for really simple tasks (i.e. summarization/classification). GPT-4 isn't necessary for "most tasks"; it's only really useful for the really complex ones that humans have trouble with. I'd say GPT-3.5-turbo is in the sweet spot for "most tasks". 3.5 appears to have lower performance than the GPT-3 davinci model, but it's a heck lot cheaper.
