Trellis 2 Review

Depends

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

· 1 month ago

Buy only if you want hosted convenience — the underlying Microsoft model is open source and free to run elsewhere. Skip it if you need production-clean meshes, vendor support, or a documented security posture.
