I don't even get why people wouldn't use normal GPT API (OpenAI completions) instead. Isn't it exactly the same except that ChatGPT is primed to be more conversational (which in many cases as the one in the OP is just noise anyway)?

There are some differences. For example ChatGPT underwent an extra finetuning step using reinforcement learning and it supports 8k tokens instead of 4k.
