On that same vein, I had just tried Opus 4.1 yesterday, and it succesfully completed tasks that Sonnet 4 and Opus 4 failed at.

When it came out on Tuesday I wanted to throw my laptop out of the window. I don't know what happened but results were total garbage earlier this week. It got better the past couple days but so far with gpt-5 being able to solve problems without as much correction I'm going to use it more.

Interesting, I've had the complete opposite experience. Opus 4.1 feels like a generational improvement compared to GPT-5.

It is funny how it can be like this sometimes. I think a lot depends on coding styles, languages, prompting, etc.

And it's almost 10x cheaper via flex, and in #1 position on lmarena. It's not even close.
