Evidence claims:
- [upstream_claim] README: scripts for LoRA training of Wan2.1/2.2, HunyuanVideo (and 1.5), FramePack, FLUX.1 Kontext, Qwen-Image and others; described as under development with possible breaking changes and 'unofficial and not affiliated with the official repositories of these architectures'. · source: https://github.com/kohya-ss/musubi-tuner
- [upstream_claim] README guidance: 12GB+ VRAM recommended for image training and 24GB+ for video; at 12GB use resolution about 960x544 or lower with --blocks_to_swap and --fp8_llm; 64GB+ system RAM recommended (32GB plus swap may work). · source: https://github.com/kohya-ss/musubi-tuner
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.

Rights:
- code: license=mixed: Apache-2.0 plus upstream model-code licenses hosting=permitted redistribution=restricted modification=restricted training=unknown · No single license: README says hunyuan_model and hunyuan_video_1_5 code follows the HunyuanVideo / HunyuanVideo 1.5 licenses; wan and frame_pack directories and other code are Apache-2.0. Check the Hunyuan license before reusing those directories. · evidence: https://github.com/kohya-ss/musubi-tuner
- model_weights: license=unknown hosting=unknown redistribution=unknown modification=unknown training=unknown · Weights of base models loaded by this tool carry their own licenses (for example FLUX.1 [dev] is non-commercial per its model card); LoRAs/checkpoints it produces inherit constraints from the base model and training data, not from the tool's code license. Not assessed here.
