TRELLIS 2 vs CSM AI: Workflow Comparison and Test Criteria

Mar 17, 2026

TRELLIS 2 and CSM AI can both participate in an image-to-3D workflow, but a feature list is not proof that either one creates a better production asset. This page separates documented capabilities from claims that require actual exported files.

Quick answer

  • Choose TRELLIS 2 on trellis2.com when you want the Microsoft TRELLIS.2 model, resolution and sampling controls, PBR-oriented GLB output, browser preview, and a transparent upstream code/model source.
  • Evaluate CSM AI when its current hosted workspace, editing, organization, export, or team workflow better matches your production process.
  • For geometry or texture quality, run the same images through both products and inspect the exported assets. Screenshots alone are insufficient.

What TRELLIS 2 documents

Microsoft describes TRELLIS.2 as a 4B-parameter image-to-3D model using O-Voxel and compact structured latents. Official materials document:

  • output resolutions from 512³ to 1536³
  • open-surface, non-manifold, and enclosed-interior handling
  • base color, roughness, metallic, and opacity attributes
  • GLB export in the reference implementation
  • MIT-licensed model and code, with separate terms for some dependencies

The trellis2.com web workflow adds remote generation, browser GLB preview, download, and credit-based controls.

Primary sources: TRELLIS.2 project and GitHub repository.

What to verify in CSM AI

CSM is a separate hosted product whose features and pricing can change. Before choosing it, verify the current product directly:

  • supported input modes

  • export format

    s

  • material-map availability

  • mesh cleanup/editing tools

  • private versus public assets

  • commercial-use terms

  • storage and project history

  • API or team features

Use CSM's current product site as the source of truth. This article deliberately avoids copying a price or generation-time claim that could become stale.

Required benchmark

For a fair TRELLIS 2 vs CSM test:

  1. use the same source files without hidden preprocessing

  2. publish the selected settings and product versions

  3. record failures, retries, queue time, and generation time

  4. export the original model file

    s

  5. inspect hidden surfaces, silhouette, polygon structure, UVs, texture maps, file size, and import warnings

  6. report cleanup time separately

Until this dataset exists, statements such as “cleaner topology,” “faster,” or “better textures” are opinions, not evidence.

Start with your actual pipeline

Use TRELLIS 2 premium generation for a TRELLIS-first GLB workflow. If you are evaluating several hosted models, use the image-to-3D converter and keep the source image and acceptance checklist constant.
