# Floyo FLUX.2 [pro] Custom Node
|
||
|
||
Custom ComfyUI node for Floyo that wraps the Black Forest Labs FLUX.2 **[pro]** API. URL-first (no local file paths): you pass URLs and get back a signed output URL for downstream Floyo nodes to download.
|
||
|
||
## Features
|
||
- Text-to-image generation with width/height, seed, safety tolerance, and output format controls.
|
||
- Image editing with multi-reference support (`input_image` + up to 7 extra refs).
|
||
- Clear URL-only inputs/outputs to match Floyo’s storage pipeline.
|
||
- Configurable API key via `config.ini` or `BFL_API_KEY` env var.
|
||
- Built-in polling with basic error handling and timeouts.
|
||
|
||
## Installation
|
||
Repo layout (mirrors Floyo Seed API style):
|
||
- `nodes/` → node code and helpers
|
||
- `config.ini` → API key placeholder
|
||
- `requirements.txt`
|
||
- `README.md`, `__init__.py`
|
||
|
||
1. Place this repository folder (e.g., `Flux2-Pro`) into `ComfyUI/custom_nodes/`.
|
||
2. Install dependencies:
|
||
```bash
|
||
cd Flux2-Pro # or your folder name under custom_nodes
|
||
pip install -r requirements.txt
|
||
```
|
||
3. Add your key to `config.ini` or export it:
|
||
```ini
|
||
[API]
|
||
BFL_API_KEY = <your_real_key>
|
||
```
|
||
```bash
|
||
export BFL_API_KEY=<your_real_key>
|
||
```
|
||
4. Restart ComfyUI.
|
||
|
||
## Nodes and I/O
|
||
### FLUX.2 [pro] Text-to-Image (`Flux2ProTextToImage`)
|
||
- **Inputs (required):** `prompt`, `width`, `height`
|
||
- **Inputs (optional):** `seed` (`-1` = random), `safety_tolerance` (0-6), `output_format` (`jpeg`/`png`)
|
||
- **Output:** `image_url` (STRING, signed URL valid for ~10 minutes)
|
||
|
||
### FLUX.2 [pro] Image Edit (`Flux2ProImageEdit`)
|
||
- **Inputs (required):** `prompt`, `input_image` (IMAGE tensor) or `input_image_url` (URL). If both are set, URL wins.
|
||
- **Inputs (optional):** `input_image_2` … `input_image_8` (IMAGE tensors) and matching `input_image_2_url` … `input_image_8_url`. URLs win over tensors. Keep total refs <= 8. `width`, `height` (0 = match input), `seed` (`-1` = random), `safety_tolerance`, `output_format`
|
||
- **Output:** `image_url` (STRING, signed URL valid for ~10 minutes)
|
||
|
||
## Usage Notes
|
||
- The returned URL expires quickly; run your Floyo download/output node immediately after this node.
|
||
- API statuses handled: `Ready`, `Pending`, and error/moderation states. Failures return an error string in the node output.
|
||
- Keep total reference images within FLUX.2 [pro] limits (max 8 images, 9MP total). Width/height must be multiples of 16; `0` uses the input image dimensions for edits. Max resolution 4MP (e.g., 2048x2048).
|
||
- When connecting ComfyUI image tensors, the node auto-converts to base64. If you prefer URLs, fill the URL fields instead.
