ComfyUI official tutorials (captured 2026-10-23): Wan2.2 models are Apache-2.0 and "support commercial use"; the hybrid Wan2.2-TI2V-5B (text+image to video) "should fit well on 8GB vram with the ComfyUI native offloading", with 14B variants for higher quality; templates use Comfy-Org repackaged weights. LTX-2.5 workflows (T2V, I2V, first-last-frame; optional prompt enhancer) need the latest ComfyUI and use gated Hugging Face repos (Lightricks/LTX-2.5 and a pixel-spatial-upscaler IC-LoRA), under the LTX-2.x community licence with a paid licence for entities >= $10M revenue (C3-B364-01); the Lightricks node README states 32 GB+ VRAM for its LTX-2 workflows (C3-B334-01). Docs warn that missing core nodes usually mean a stable release lags nightly. Takeaway for agents: Wan 2.2 5B is the low-VRAM, commercially clean local option; LTX/H3 need more VRAM and licence checks. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Commercial-use statements are the docs' own wording; check each model licence version. Limitations: VRAM statements are vendor-doc guidance, not tested. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
