ComfyUI venice.ai Flux/SDXL/LLM API Nodes

An unofficial custom node implementation for ComfyUI that integrates with venice.ai's Flux and SDXL image generation models (and upscale + text gen). This project is adapted from ComfyUI-FLUX-TOGETHER-API to work with the venice.ai API.

Disclaimer: I just made this on a whim because someone wanted something similar to Together.AI custom nodes but have them use venice instead and also, I don't have access to any API keys for any of the mentioned services. i guess it should work, sometimes?

Implemented stuff from venice api:

• Image generation endpoint
• Chat completion/Text generation endpoint
• Upscale image endpoint (untested)

Missing-ish Stuff from venice api:

• A way to update hardcoded things like:

  • available models using list models enpoint
  • available style presets using styles endpoint

• Some Validation on queue for API limits like prompt max length or width/height

  • these are different for different models so this isnt planned to be implemented unless the api exposes those limits somehow

If there's no "untested" on any of the points it means it should work but there's not been extensive testing on it

Below ReadMe text is slightly altered from original Flux Together API readme, it was not reworked or anything so it might not be correct or up to date

Features

• Direct integration with venice.ai's Flux and SDXL models
• Support for flux-dev, flux-dev-uncensored, fluently-xl and pony-realis (status: 25th Jan 2025)
• Support for all LLMs venice.ai offers (status: 25th Jan 2025)
• Configurable parameters including steps, guidance scale, and dimensions
  • including fake-ish batch size (just 2 requests after one another returned as 1 output)
• Negative prompt support (ignored when Flux is selected)
• Error handling i guess

Installation - these instructions are a mess

1. Clone this repository into your ComfyUI custom_nodes directory:

cd ComfyUI/custom_nodes
git clone https://github.com/DraconicDragon/ComfyUI-Venice-API.git

2. Install the required dependencies: (this might be done by comfyui automatically on restart already?)

pip install -r requirements.txt

OR From the Comfyui Folder (this one is usually preferred if you have portable edition)

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

outdated, configure in node, in future this will likely be in comfy settings 3. Edit the config.ini file in the root directory and add venice.ai API key:

[API]
API_KEY = your_api_key_here
BASE_URL = https://api.venice.ai/api/v1

Configuration

1. Get your API key from venice.ai
2. Add your API key to the configuration file yeah no just add it in the nodes

Usage

1. Start ComfyUI
2. Find the "Generate Image (Venice)" in the node browser (double-click empty space in ComfyUI) 2.1. or the Generate Text (Venice) node
3. Configure the parameters:
   • Prompt: Your image generation prompt
   • Negative Prompt: Elements to avoid in the generation
   • Steps: Generation steps (1-30)
   • Width: Image width (512-2048)
   • Height: Image height (512-2048)
   • Seed: Generation seed
   • CFG: Guidance scale (0.1-15.0)

For detailed usage instructions, see USAGE.md

Parameters

Parameter	Type	Range	Default	Description
prompt	string	-	""	Main generation prompt
negative_prompt	string	-	""	Elements to avoid
steps	integer	1-30	20	Number of generation steps
width	integer	512-1280?	1024	Image width
height	integer	512-1280?	1024	Image height
seed	integer	0-MAX_INT	0	Generation seed
cfg	float	0.1-15.0	3.5	Guidance scale
