I don't get the point of this code example from Jev
I'm looking at the latest Jev model from Typesafe. I see they have a code example on their website, using Jev to validate extracted data
https://docs.typesafe.ai/cookbooks/sde_cascade
What I don't get is what's the point of this? In the example they've used gpt-5.4-mini to extract and then Jev to check those extractions. To solve this problem, would it's be better (and cheaper) to just use a model like Deepseek 4.1?
