A streamlined and simplified custom node for ComfyUI that provides direct access to local Ollama models. This node allows you to send prompts and images to your local Ollama instance and receive text-based responses.

This project is a heavily modified and stripped-down version of the original ComfyUI-OllamaGemini by @al-swaiti. All credit for the original concept and implementation goes to them.

This simplified version can be found at https://github.com/BobRandomNumber/ComfyUI-BasicOllama.

🚀 Features

Direct Ollama Integration: Seamlessly connect to your local Ollama instance.
Text and Image Support: Send both text prompts and images to multimodal Ollama models.
Multiple Image Inputs: Input up to five images for analysis.
Structured Output: Get cleaned, structured output from the Ollama model.
Easy Configuration: Quickly set up your Ollama URL.

`ollama_model`	`COMBO`	A list of available Ollama models on your local instance.
`keep_alive`	`INT`	The duration (in minutes) that the Ollama model should remain loaded in memory after the request is complete.
`structure_output`	`BOOLEAN`	If `True`, the output will be cleaned and structured.
`prompt_structure`	`COMBO`	A selection of prompt templates to structure your prompt for various models.
`structure_format`	`STRING`	A custom format for the structured output.

⚙️ Configuration

By default, the BasicOllama node will attempt to connect to your Ollama instance at http://localhost:11434.

If your Ollama instance is running on a different URL, you can change it by editing the config.json file located in the ComfyUI-BasicOllama directory:

{
  "OLLAMA_URL": "http://your-ollama-url:11434"
}
