An unofficial custom node implementation for ComfyUI that integrates with venice.ai's Generative AI services such as Image, Text and TTS Generation models (as well as Upscale and Enhance). This project is adapted from ComfyUI-FLUX-TOGETHER-API to work with the venice.ai API.
Note: TTS is in Beta per Venice (as of 15th June 2025). The node for it "Generate Speech (Venice)" is set to BETA/Experimental too. To be able to find it with node search you have to enable "Show experimental nodes in search" setting in ComfyUI.

Disclaimer: I originally made this on a whim because someone wanted something similar to Together.AI custom nodes but have them use venice instead. I'm also not affiliated with Venice.AI. Idk is this good enough for a disclaimer or something

Nodes: (Text gen node is missing but will be updated soon)

Image and Text models (as of 15th June 2025 | for Speech gen only tts-kokoro is available)

~~# todo: inpainting~~ Deprecated by venice, new thing is coming for it at some point

todo: actual log, maybe separate logging file for less clutter from comfyui stuff, maybe, maybe... eeeee

todo: LLM characters list

todo: use variants api (currently in beta) | idk what happened to this

Todo: chat history/memory/context for LLM

todo

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
  - i'd have an error thrown before it gets sent to api about some value being too high or too low (though api should send error back for now either way)
  - maybe the api already exposes those limits, the steps limit is afaik at least, need to look into it

Below ReadMe text is only slightly altered from original Flux Together API readme, it was not really reworked or anything so its likely not 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-realism (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

Before proceeding, check if you can find these nodes through ComfyUI-Manager interface rather than following the instructions.

Expand me to see harder instructions

1. Clone this repository into your ComfyUI custom_nodes directory:

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

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

Configuration

Get your API key from venice.ai
Add your API key in ComfyUI settings > VeniceAI

Usage

Start ComfyUI
Find the "Generate Image (Venice)" in the node browser (double-click empty space in ComfyUI)
- or the Generate Text (Venice) node
Configure the parameters:
- Prompt: Your image generation prompt
- Negative Prompt: Elements to avoid in the generation
- Steps: Generation steps (1-30 or 50)
  - Some models only allow maximum 30 steps while others allow 50. See venice api docs. The node and/or API should throw an error if the steps are set too high
- Width: Image width (0-2048)
- Height: Image height (0-2048)
  - Venice.AI upper limit is 1280 for width and height but the setting allows higher in case that limit is changed upwards
- Seed: Generation seed
- CFG: Guidance scale (0.0-20.0)

For detailed usage instructions, see USAGE.md (not reworked)
