Qwen3 8B FP8 Native For FLUX2

--- license: apache-2.0 base_model: Qwen/Qwen3-8B library_name: safetensors tags: - qwen3 - flux2 - comfyui - text-encoder - fp8 - safetensors --- # Qwen3-8B Native FP8 Text Encoder for FLUX.2 ComfyUI This repository contains a ComfyUI-native FP8 conversion of `Qwen/Qwen3-8B` intended for FLUX.2 / Flux 2 text-encoder workflows. It was converted from the BF16 `Qwen/Qwen3-8B` weights, not from HF compressed FP8 shards. In practice this avoids the extra compressed-FP8 scale conversion step and loaded cleanly in ComfyUI's `CLIPLoader` with `type=flux2`. ## File - `Qwen3-8B-FP8-native-bf16.safetensors` - Size: 8,191,089,400 bytes - SHA256: `2f3ef1c5dac47bc7f423b8b306c4ad5ddfdface9da7efa3f250da9d8b440af84` ## Conversion - Source model: `Qwen/Qwen3-8B` - Floating 2D tensors were cast to `torch.float8_e4m3fn`. - Other tensors, such as norms and scalar parameters, were kept in BF16. - Output is a single `.safetensors` file for easy placement in `ComfyUI/models/clip`. The included `convert_qwen3_bf16_to_native_fp8.py` script documents the exact local conversion pattern used for this upload. ## Usage Place the safetensors file in one of: - `ComfyUI/models/clip/` - `ComfyUI/models/text_encoders/` Then use `CLIPLoader` with `type=flux2` and select `Qwen3-8B-FP8-native-bf16.safetensors`. This is not a standalone chat model. It is intended as a text encoder for image generation workflows, especially FLUX.2 workflows that expect Qwen3 8B. ## FLUX.2 note This upload contains only Qwen-derived weights under the Apache-2.0 license. It does not include Black Forest Labs FLUX.2 weights, VAE files, or BFL text encoder files. To use official BFL FLUX.2 assets, accept and download them from the official BFL repository according to its license terms: https://huggingface.co/black-forest-labs/FLUX.2-klein-base-9B
