FLUX.1-schnell is the recommended model — fast (4 steps), Apache 2.0 licensed, excellent quality.
```bash
# Download (~8GB) — place in ComfyUI/models/checkpoints/
wget https://huggingface.co/black-forest-labs/FLUX.1-schnell/resolve/main/flux1-schnell.safetensors \
-O ~/ComfyUI/models/checkpoints/flux1-schnell.safetensors
> ⚠️ **FLUX.1-schnell is a gated model on HuggingFace.**
> A bare `wget` on the URL returns HTTP 401. You must:
> 1. Accept the license at https://huggingface.co/black-forest-labs/FLUX.1-schnell (click **"Agree and access repository"** — one-time)
> 2. Create a HuggingFace access token with **Read** permissions at https://huggingface.co/settings/tokens
# Or use huggingface_hub:
#### Option A — `huggingface-cli` (recommended)
```bash
# Install the HuggingFace Hub CLI
pip install huggingface_hub
# Log in — paste your Read token when prompted
huggingface-cli login
# Download (~8GB) directly into ComfyUI checkpoints
huggingface-cli download black-forest-labs/FLUX.1-schnell \
flux1-schnell.safetensors \
--local-dir ~/ComfyUI/models/checkpoints/
```
#### Option B — `wget` with Authorization header
```bash
wget --header="Authorization: Bearer hf_YOUR_TOKEN_HERE" \
https://huggingface.co/black-forest-labs/FLUX.1-schnell/resolve/main/flux1-schnell.safetensors \
-O ~/ComfyUI/models/checkpoints/flux1-schnell.safetensors
```
> Replace `hf_YOUR_TOKEN_HERE` with your actual HuggingFace token from https://huggingface.co/settings/tokens
#### Alternative: fp8 quantized variant (~8.1GB, faster inference)
If you want slightly faster inference with near-identical quality, the fp8 quantized version is also available:
```bash
huggingface-cli download black-forest-labs/FLUX.1-schnell-fp8 \
flux1-schnell-fp8.safetensors \
--local-dir ~/ComfyUI/models/checkpoints/
```
> **Download note:** Both variants are ~8GB — expect 10–30 minutes depending on connection speed.
You'll also need the CLIP and VAE models — see the [ComfyUI FLUX guide](https://github.com/comfyanonymous/ComfyUI/blob/master/README.md) for full model list.
