It's good. My brief exposure to it suggests it deserved a new product name.
One thing that I would like to try is Pi code agent. People seems to like it. GPT allows you to use it on subscription, but Anthropic cut that off on Max subscription. One more incentive to try something new. Also, I feel that I rely on Anthropic too much and none of these guys could be trusted. Next step -> foray into the Chinese models (admittedly not as good). Hopefully, they will get good enough soon.
I think that's important actually to have constant access to two so you can understand what their strengths are. Plus it's easier mentally to switch your alt account than your workhorse.
