What is TRELLIS.2-4B?

OMW evidence review3 Oct 2026

Open Model Weights records TRELLIS.2-4B as a Pending verification-parameter image to 3d open-weight model in the TRELLIS.2 family, with Microsoft listed as the developer. The checked source repository provides 9 recognized weight artifacts, format evidence for Safetensors and a verified context window of Not declared in checked config/model card. Values that are not evidenced in the checked sources remain explicitly undisclosed or unknown.

The repository declares MIT. Commercial use allowed under MIT conditions. Open Model Weights reports the checked license evidence and classification; this is not legal advice.

No base model is declared in the checked standard lineage metadata, so Open Model Weights does not infer one. A training recipe and standard training-data disclosure were not found by the current verifier.

DEPLOYMENT PROFILE

Weight memory, without pretending it is a deployment guarantee.

These bars visualize weight-only decimal-GB estimates. They exclude KV cache, activations, runtime overhead, optimizer state and sharding.

WEIGHT-ONLY MEMORY

No weight-only memory estimate is available from the verified parameter count.

LINEAGE & PROVENANCE

What the checked sources disclose — and what they do not.

Open Model Weights does not infer a hidden base model or training corpus when the checked sources do not declare one.

RUNTIME SIGNALS

Compatibility claims stay attached to their evidence level.

Declared and model-card-mentioned runtimes are discovery signals. They are not treated as Open Model Weights runtime tests unless explicitly measured.
