I've been working with it, and so far it's been very impressive. Better than Opus in my feels, but I have to test more, it's super early days
Just early anecdote from trying to build that 1 SaaS application though.
What really impressed me was when I told it that I wanted a particular component’s UI to be cleaned up but I didn’t know how exactly, just wanted to use its deep design expertise to figure it out, and it came up with a UX that I would’ve never thought of and that was amazing.
Another important point is that the error rate for my session yesterday was significantly lower than when I’ve used any other model.
Today I will see how it does when I use it at work, where we have a massive codebase that has particular coding conventions. Curious how it does there.
