ComfyUI Together.ai FLUX API Node

A custom node implementation for ComfyUI that integrates with Together.ai's FLUX image generation models. This project is inspired by and adapted from ComfyUI-FLUX-BFL-API to work with the Together.ai API.

Features

• Direct integration with Together.ai's FLUX models
• Support for FLUX.1-schnell-Free model
• Configurable parameters including steps, guidance scale, and dimensions
• Negative prompt support
• Error handling and retry mechanisms

Installation

1. Clone this repository into your ComfyUI custom_nodes directory:

cd ComfyUI/custom_nodes
git clone https://github.com/BZcreativ/ComfyUI-FLUX-TOGETHER-API.git

2. Install the required dependencies:

pip install -r requirements.txt

OR From the Comfyui Folder

 ./python_embeded\python.exe -m pip install -r ComfyUI\custom_nodes\ComfyUI-FLUX-TOGETHER-API\requirements.txt

3. Create a config.ini file in the root directory with your Together.ai API key:

[API]
together_api_key = your_api_key_here

Configuration

1. Get your API key from Together.ai
2. Copy the config.ini.example to config.ini
3. Add your API key to the configuration file

Usage

1. Start ComfyUI
2. Find the "Together API Node" in the node browser
3. Configure the parameters:
   • Prompt: Your image generation prompt
   • Negative Prompt: Elements to avoid in the generation
   • Steps: Generation steps (1-100)
   • Width: Image width (512-2048)
   • Height: Image height (512-2048)
   • Seed: Generation seed
   • CFG: Guidance scale (0.0-20.0)

For detailed usage instructions, see USAGE.md
