## FLUX.1 Support Comparison

FLUX.1 (Black Forest Labs, 2024-2025) is the leading open-source text-to-image model. Support varies significantly across UIs:

| UI                   | FLUX.1 Support                | SD3.5 Support  | Notes                                       |
| -------------------- | ----------------------------- | -------------- | ------------------------------------------- |
| **ComfyUI**          | ✅ Full native support         | ✅ Full support | Best choice for FLUX; node-based workflow   |
| **SD WebUI Forge**   | ✅ Full support via Forge fork | ✅ Full support | Recommended if you prefer traditional UI    |
| **A1111 (original)** | ⚠️ Limited / via extension    | ⚠️ Limited     | Not recommended for FLUX; use Forge instead |
| **Fooocus**          | ✅ FLUX variant available      | ✅ Partial      | Simplified interface, less control          |

### Recommended Setup for FLUX.1

**ComfyUI** (max control):

```bash
git clone https://github.com/comfyanonymous/ComfyUI
cd ComfyUI
pip install -r requirements.txt
# Download FLUX.1 model to models/diffusion_models/
python main.py --listen 0.0.0.0
```

**SD WebUI Forge** (familiar UI):

```bash
git clone https://github.com/lllyasviel/stable-diffusion-webui-forge
cd stable-diffusion-webui-forge
./webui.sh --listen
# FLUX.1 models supported natively
```

{% hint style="warning" %}
**A1111 users:** The original AUTOMATIC1111 repo has limited FLUX support. Switch to **Stable Diffusion WebUI Forge** (a drop-in replacement) for full FLUX.1 and SD3.5 support.
{% endhint %}

### FLUX.1 Model Variants

| Model          | Size | Use Case                     | UI Compatibility             |

## Summary

| Choose               | When You Want                                      |
| -------------------- | -------------------------------------------------- |
| **Fooocus**          | Simplicity, quick results, Midjourney-like         |
| **SD WebUI (A1111)** | SD1.5/SDXL features, extensions, community support |
| **SD WebUI Forge**   | A1111 features **+ full FLUX.1 / SD3.5 support**   |
| **ComfyUI**          | Control, automation, performance, FLUX workflows   |

Most users start with **Fooocus**, graduate to **SD WebUI Forge** for more features and FLUX support, and move to **ComfyUI** for production workflows.

### 2025 Recommendation for FLUX.1 & SD3.5

* **Best for FLUX.1:** Use **ComfyUI** (maximum control) or **SD WebUI Forge** (familiar A1111-style UI)
* **Avoid A1111 (original)** for FLUX/SD3.5 — use Forge instead, which is a drop-in replacement with full new model support
