VERDICT

Should I use Trellis 2?

AI-powered image to 3D model generator by Microsoft Research. Image to 3D in 1-3 minutes, GLB export, no GPU required. - trellis2.app

Depends. Good pick for indie devs and hobbyists who need fast 3D mockups from images without a GPU. Skip paying for it if you have a decent machine — the underlying model is free and open source — and don't expect production-ready topology or vendor support.

Confidence

Medium. Based on ~20 public sources; many snippets were truncated, so exact paid pricing and support quality could not be verified.
