Personally, I hope they continue sticking with Claude as I feel it has the best answers of all providers.
At the moment is ChatGPT 4o Mini smarter? Yes. But when Haiku 3.5 is released it will be superior again (which shouldn't be too long from now.) AI are constantly leapfrogging each other and I don't want them switching to the flavor of the month constantly when Claude has a consistently superior tone of writing.
Just in general I can't stand how ChatGPT writes, nor do I like how it structures replies. It's also overly verbose. Perhaps a way to make everyone happy is to allow us to choose our simple/quick LLM of choice per account.
