Trellis.2 AI 3D is a hosted web front end for Microsoft Research's open-source Trellis.2 model, an image-to-3D system built on a native 3D latent representation called O-Voxel that jointly models geometry and PBR materials. That design lets the model work from 3D data directly rather than relying on multiview baking or 2D proxies, which is why it can produce open surfaces, thin geometry and intricate non-manifold detail that trip up earlier pipelines. The 4-billion-parameter, flow-matching transformer is released with open weights under an MIT licence, and trellis3d.net runs it on its own servers so visitors do not need a GPU.
The workflow is deliberately short. You upload a reference image in PNG, JPEG or WebP up to 20MB, choose output resolution (512, 1024 or 1536), texture resolution (1024, 2048 or 4096) and optionally enable remesh decimation with a target triangle count, then submit. Advanced panels expose guidance strength, rescale and sampling steps for the shape SLAT and texture SLAT stages, alongside super-resolution parameters. Finished assets come back as GLB files containing the mesh and full PBR maps, ready for Blender, Unity, Unreal Engine or a browser viewer, and you can additionally explore and download public community creations from the gallery.
It is worth being clear about provenance: this is an independent third-party platform, not an official Microsoft service. Microsoft published the Trellis.2 model and open weights, while trellis3d.net provides the hosting, credit system, gallery and subscription plans. Access is credit-based, with a free experience tier and monthly subscriptions starting around $13.90 for the Base plan and rising through Pro, Max and Ultra tiers that add credits and priority queueing; annual billing is discounted. Assets created on paid tiers are described as private and customer-owned, with dedicated account support.
