I was opencode user, but like few months ago tried pi and never looked back. Pi with open models is absolutely mind-blowing - my agents run with speeds not achievable with any remote frontier model - they certainly not as smart, but it doesn't matter because they do their "work done" perfectly and fast.
All problems I had with opencode are not presented in pi - it looks it's the best approach to guarantee most productive coding environment - speed, simplicity, transparency, absolute customization. I will certainly try this 2.0, maybe they have now improvements.
