I much prefer Claude over ChatGPT, based on my experience using both extensively. Claude understands me significantly better and seems to "know" my intentions with much greater ease. For example, when I request the full file, it provides it without any issues or unnecessary reiterations (ChatGPT fails after me repeatedly instructing it to), often confirming my request with a brief summary beforehand, but nothing more. Additionally, Claude frequently asks clarifying questions to better understand my goals, something I have noticed ChatGPT never did. I have found it quite amazing that it does that.
So... as long as this money helps them improve their LLM even more, I am all up for it.
My main issue is quickly being rate-limited in relatively long chats, making me wait 4 hours despite having a subscription for Pro. Recently I have noticed some other related issues, too. More money could help with these issues, too.
To the developers: keep up the excellent work and may you continue striving for improvement. I feel like ChatGPT is worse now than it was half a year ago, I hope this will not happen to Claude.
