ComfyUI Grok Proxy Nodes

ComfyUI custom nodes for Grok image and video models through a local OpenAI-compatible media proxy.

This extension is proxy-neutral. Use any local proxy that exposes compatible Grok media routes; for example, set the node's proxy_base_url to your proxy's /v1 endpoint.

Install

From your ComfyUI checkout:

cd custom_nodes
git clone https://github.com/zoidypuh/ComfyUI-Grok-Proxy.git

Then restart ComfyUI.

Proxy Settings

Each node has proxy_base_url and api_key inputs. Defaults can also be set with environment variables:

export COMFY_GROK_PROXY_BASE_URL=http://127.0.0.1:8317/v1
export COMFY_GROK_PROXY_API_KEY=dummy

The default URL is http://127.0.0.1:8317/v1, and the default API key is dummy. Change either value in the node UI if your proxy uses a different port or token.

Nodes

• Grok Image
• Grok Image Edit
• Grok Video
• Grok Video Edit
• Grok Video Extend
• Grok Reference-to-Video
• Grok Proxy Video Generate (Compatibility)

Models

Model dropdowns show normal, non-prefixed Grok model names.

The default image models are:

• grok-imagine-image
• grok-imagine-image-quality

The default video models are:

• grok-imagine-video
• grok-imagine-video-1.5-preview

When /models is available, the node refreshes the dropdowns from the proxy, strips any xai/ prefix for display, and filters out grok-imagine-image-pro.

Routes

The proxy should expose OpenAI-style JSON routes:

• GET /models
• POST /images/generations
• POST /images/edits
• POST /videos/generations
• POST /videos/edits
• POST /videos/extensions
• GET /videos/{request_id}

Generated videos are downloaded into ComfyUI's output/grok_proxy/ directory. Generated images are also saved into output/grok_proxy_image/ and returned as ComfyUI IMAGE tensors.
