The problem is that Pi, on any third party harness, cannot really compete with codex or cc due to subscriptions.

Anthropic is the only provider trying to lock in their users by using the dirty tactics:

- Prevent subscription usage on third party harnesses

- Append "Co-authored by Claude ..." to commit messages

I also test harness with "Ship Harness Bench", jcode with its browser integration gives the best results

The most astonishing thing to me is that Pi harness is basically as efficient as the Codex/Claude. I wonder if the same is true for the smaller models in the 9-32B range? I would expect that these models need more steering, but again I was not expecting this result either.

It’s more efficient, no? Token wise at least.
