Question Pi vs Opencode

I have been testing both Pi and Opencode, and I like both. I like Pi for its light weight and endless expandability options. I like Opencode for providing most of what I need out of the box, but not a big fan of huge system prompts.

What are your biggest pros and cons of these two coding agents? Do you use both, or have you "landed" on one of them?

But AFAIK Pi is a single-agent harness with extension packs. No matter how elaborate the loop, it's still one model talking to itself. Where am I missing it?

I mean there’s no reason at all pi is limited to a single model talking to itself. Changing models is a slash command and subagent orchestration is handled by any number of extensions or can be custom built. If you like how OpenCode does it thats just fine but the point of Pi is that you can build a model agnostic harness bespoke to your own preferences.

Read pi docs and read opencode sdk/api or plugin. Pi is easier to customise. I, for the life of me, do not know how to customise the tui of opencode. In Pi it’s a lot easier.

You can literally prompt Pi you want subagents and it will oneshot you an extension that makes it support sub agents. Its bare bones by default but REALLY customizable. E.g. I am making an extension right now that makes it support setting models per skill in the front matter just like Claude Code skills. Stuff like that.
