I think there's a sweet spot for it. If a model can't do a task, iterating won't help. If a model can do it reliably, there's no need to iterate.

If it can do it, but unreliably, that's where you would get major gains from iterating. I think the Chinese models are in that sweet spot, for many tasks. I would love to test that.

I started working on my own fusion system yesterday. I'm not sure how to benchmark it though.

The thing I'm most interested in is reliability. Going from 90% to 95% on a benchmark doesn't seem like much but you've cut the error rate in half.
