What's your benchmark for calling an AI-generated model "usable"?

I've been experimenting with a few AI 3D tools lately, and I've realized generating a decent-looking model is only the beginning.

What usually determines whether I keep an asset is how much work comes afterward. Bad topology, messy meshes, difficult UVs, or a model that falls apart during rigging can easily erase whatever time was saved.

One platform I found while comparing workflows was V2Fun, mainly because it seems to cover more of the pipeline instead of stopping at model generation. Still, I'd rather hear from people who've actually tested these tools.

When you're evaluating AI-generated models, what's the first thing you check before deciding they're worth keeping?
