ComfyUI-AnyLLM

ComfyUI-AnyLLM

A ComfyUI custom node pack for calling LLM providers.

This pack currently includes Google Gemini nodes powered by the official google-genai Python SDK.

Install

Install via ComfyUI Manager

1. Open ComfyUI Manager
2. Install this repository as a custom node

If the repository is not listed yet, you can still install it by URL using Manager's "Install via Git URL" feature.

Manual install (git)

Clone into your ComfyUI custom_nodes folder:

git clone <YOUR_GIT_URL> ComfyUI/custom_nodes/ComfyUI-AnyLLM

Then install Python dependencies in the same Python environment ComfyUI uses:

pip install -r ComfyUI/custom_nodes/ComfyUI-AnyLLM/requirements.txt

Restart ComfyUI.

Nodes

Get Environment Variable (AnyLLM)

Category:

• AnyLLM/Utils

Inputs:

• name (STRING) - environment variable name, e.g. GOOGLE_API_KEY

Outputs:

• value (STRING)

Notes:

• Raises an error if the variable is missing or empty.

Google Gemini (AnyLLM)

Category:

• AnyLLM/Google

Inputs:

• model (dropdown)
• api_key (STRING) - connect from Get Environment Variable (AnyLLM)
• prompt (STRING)
• images (IMAGE, optional) - image batch input
• response_images (BOOLEAN) - request image outputs when supported by the model

Outputs:

• text (STRING)
• images (IMAGE)

Notes:

• If the model returns images, they are output as images.
• If the model does not return images, the node passes through the input images (or returns a small blank image if none was provided).

Notes

• Provider/model capabilities differ; not every model supports images.
• API keys are passed only at runtime (not stored).

Errors

This pack raises Python exceptions on failures (missing keys, missing deps, API errors) so the error shows up directly on the node in ComfyUI.
