Evidence claims:
- [upstream_claim] README: adds GGUF quantization support; the 'GGUF Unet loader' (category bootleg) loads .gguf files from ComfyUI/models/unet; T5 quants use *CLIPLoader (gguf); pre-quantized links for Flux.1-dev/schnell and SD 3.5 Large/Large Turbo; LoRA loading described as experimental. · source: https://github.com/city96/ComfyUI-GGUF
- [upstream_claim] README calls the project 'very much WIP', says quantization was not feasible for conv2d UNET models but works better for transformer/DiT models, requires a ComfyUI recent enough for custom ops, and notes macOS Sequoia seems to need torch 2.4.1 (issue #107). · source: https://github.com/city96/ComfyUI-GGUF
- [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.

- model_weights: license=unknown hosting=unknown redistribution=unknown modification=unknown training=unknown · GGUF files are converted from base models (e.g. FLUX.1 dev) and inherit their licenses. Model files these nodes load or download carry their own licenses; the node code license does not cover them. Not assessed here.
