What is FastVideo-FastH3-4-step-Preview-v1-VSA-DataFree?

OMW evidence review3 Oct 2026

Open Model Weights records FastVideo-FastH3-4-step-Preview-v1-VSA-DataFree as a 35.0498B-parameter text → video open-weight model in the FastVideo-FastH3-4-step-Preview-v1-VSA-DataFree family, with FastVideo listed as the developer. The checked source repository provides 35 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 minimax-h3-community. Commercial-use status requires manual review. Open Model Weights reports the checked license evidence and classification; this is not legal advice.

Lineage metadata declares MiniMaxAI/MiniMax-H3 as a related base model with the relation declared relationship. A training recipe and standard training-data disclosure were not found by the current verifier.

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.
