It's also annoying that OpenCode doesn't even try to support local LLMs properly.

Getting OpenCode to work is possible, but extremely manual and clunky to configure. I have written a script to automate converting my llama-server configs into an OpenCode config, and that helps, but it's not ideal.

I have seriously considered writing Yet Another Coding Harness in my free time. I have some ideas for what would make it nice.

I've used the cli agents for claude, cursor, and pi, plus several custom harnesses I've written myself from time to time as experiments (and I guess technically gastown, if we're calling that a harness).

Pi is... just fine.

It does what I need it to, has a decent selection of tooling out of the box, integrates nicely with other tools, and generally gets out of my way enough that I don't think about it much anymore.

If you can run ~30b models at decent speeds, I think most folks would be pleasantly surprised at how capable they are with pi.

Tack on some of the extensions (ex https://pi.dev/packages/pi-mcp-adapter?name=mcp and https://pi.dev/packages/pi-web-access?name=search) and I get web tooling (ex - perplexity search), access to mcps to do things like drive chrome (https://browsermcp.io/) or firefox (https://github.com/mozilla/firefox-devtools-mcp)

It's fine. Is it as good as a subsidized top tier model? Nope. Is it free and still very capable? Yup.

And personally, I've been having a LOT of fun with the pi sdk (https://pi.dev/docs/latest/sdk)

Which is something that all the other providers charge you api access rates for (ex - thousands a month).
