KakaoTalk is currently selling ChatGPT Pro at a 90% discount, so it's quite popular. I don't use conversational AI much, but I primarily use it for development purposes. ChatGPT doesn't provide a separate API, and can only be used as a conversational chatbot. Most people probably use it for Vibecoding or to efficiently manage large projects, rather than for conversational purposes. Personally, I find it a bit inconvenient to have to manually activate the conversational GPT feature. For Vibecoding, Cursor or Cloud seem much better. (Perhaps it's because I haven't used Pro...?) I've been using Cursor for quite some time, and even the lowest plan allows for 5.3 codex. (This seems to be limited to those who subscribed before the change.) For external AI applications like OpenClaw, I personally think Google AI Pro, or the more expensive Google AI Ultra, is a good option. I'm using Google AI Pro, and I've set up OpenClaw on my telebot and it's working well. The token resets every five hours, so unless you're making excessively repetitive requests, you can just take a break and try again if you hit the token limit. As a current developer, I subscribe to a lot of different things, so that might be why, but I'm not sure ChatGPT Pro is particularly attractive to me, even at 29,000 won. Would anyone who's considering buying it... please tell me what your reasons are for purchasing? (I'm curious if there's a reason I'm not aware of...)
