Just tried it - very cool indeed. I did a page loop extraction but it seems to be the same speed when I run it. The elements I am doing the loop on look pretty much the same, just different images. I think it would be great if it was able to generalize how to find an element like with css selectors for example to speed up once its sure that is the data you are looking to extract for a given loop.

Totally agree, making page loop faster is on the top of our list of things to do! There are cases where you need page loop to do quite a bit of reasoning so it will be this slow until models get faster, but we can make it a lot faster today on happy paths - stay tuned :)
