OhMyPi is essentially Claude like bloated and Pi is so barebones that many will just get frustrated trying to add bricks after bricks to make it usable for complex workflows - so I don't really see any point of it being in such benchmarks. Pi should have added option to easily add "packs" (and then also tweak tehm) sort of things. When I tried it I actually thought that's what OMP will be, but it was not. It was a different harness altogether in a way and not a nice way.
I wish we could use just the frontend of omp harness-agnostically, like the provider switching, stats dashboard, subscription pooling etc. are excellent features, but it doesn't seem inconceivable that we can have all that with a swappable "actual" harness. I've tried to make omp more pi-like by lazy loading most of the tools rather than dumping them into system prompt. haven't benchmarked this yet.
