# Hugging Face Community Notes These are useful `FLUX.2-klein` community findings from Hugging Face pages that did not all ship clean standalone workflow JSON files, but still contain setup or optimization advice worth keeping. ## Unsloth GGUF discussion Source: What looked useful: - At least one user reports a working `9B base` path by starting from the official Comfy `flux2 klein base 9b` workflow and swapping the diffusion and clip loaders to GGUF-compatible loaders. - The discussion explicitly calls out the text-encoder mismatch trap: - `4B` uses `Qwen3 4B` - `9B` uses `Qwen3 8B` - The thread also suggests keeping ComfyUI very current; some of the reported matrix-shape errors appear to come from version mismatch or wrong encoder pairing. Our take: - Good sign that community users are already adapting the official workflows instead of reinventing everything from scratch. - If you want a `9B GGUF` branch later, this discussion is one of the better breadcrumbs for why it fails and how people are fixing it. ## GuangyuanSD Blitz notes Source: What looked useful: - The page is strongly oriented around low-step speed-first `9B` usage. - Recommended settings are very explicit: - `4-5` steps - `CFG = 1` - The author says their environment was `ComfyUI 0.11`. - The repo also mentions LoRA-adapter style application paths and Blackwell-oriented quantization variants. Our take: - Even though this page did not expose a clean workflow JSON in the fetched content, the settings are concrete enough to matter. - If you try community `9B Blitz` variants later, these are the first settings I would mirror instead of guessing. ## ponpoke uncensored encoder Source: What looked useful: - It is not a workflow, but it is directly usable in ComfyUI as a replacement text encoder placed in the `models/clip` path. - The author explicitly says to pair it with the official `FLUX.2-klein-9B` DiT and standard or GGUF-compatible loader nodes. Our take: - Not something to treat as a default, but worth remembering if you ever want alternate text-encoder behavior in a `9B` setup.
