Claude seems better.
Codex just wastes tokens unnecessarily, and it doesn't seem to understand what is being said very well, something is a little strange.
For example, if you give it a link and say, "Here's a link with this and that content in it, what do you think?", it says it can't see the link. Okay, so far so good, anything can go wrong.
But it doesn't stop there, it gives a really long answer. Even though it couldn't read the link, it used its imagination and ended up writing a whole paper.
And... there are other things like that, but I can't write them all down because they're too tedious. Sorry, sorry is basically built into the chat window.
Claude is a bit cynical and frustrating, but it didn't feel like that before. As soon as I started typing, "Gemini was a fool. He just does what he thinks."
ChatGPT is also too fast in terms of token consumption, the results are vague, and the hallucinations in the answers are too severe. Anyway, my first impression isn't very good.
