Experimental nodes for ComfyUI. For more, see a/https://kubi-meta.de/ai4artsed A custom ComfyUI node for stylistic and cultural transformation of input text using local LLMs served via Ollama. This node allows you to combine a free-form prompt (e.g. translation, poetic recoding, genre shift) with externally supplied text in the ComfyUI graph. The result is processed via an Ollama-hosted model and returned as plain text.

    AI4ArtsEd Prompt Nodes for ComfyUI

    Experimental prompt transformation nodes for ComfyUI, developed as part of the AI4ArtsEd research initiative. These components support stylistic and cultural translation of prompts and images for use in educational, artistic, and cultural research contexts.

    πŸ”§ Features

    • Accepts STRING or IMAGE input from any upstream node.
    • Structured control of transformation via style_prompt, context, and instruction.
    • Supports both:
    • Produces output as STRING (for use in CLIP, chaining, or save/display).
    • Optional debug logging and model unloading for Ollama.
    • Optional API key file handling for OpenRouter.
    • Includes an image-to-text analysis node for multimodal LLMs.
    • New: Flexible text distribution node for routing strings to multiple downstream paths.

    🧹 Available Nodes

    1. AI4ArtsEd Ollama Prompt

    β†’ Uses local Ollama models (GPU/CPU) for cultural prompt rewriting.

    2. AI4ArtsEd OpenRouter Prompt

    β†’ Uses hosted LLMs via OpenRouter for stylistic transformations.

    3. AI4ArtsEd OpenRouter/Ollama ImageAnalysis

    β†’ Sends image input (as base64-encoded JPEG) to multimodal LLMs via OpenRouter (e.g. GPT-4V) or Ollama with cultural-instruction prompts.

    4. AI4ArtsEd Text Remix

    β†’ Selectively or randomly combines 1–12 text inputs.

    Inputs:

    • mode: "random", "all", or "1"–"12"
    • text_1 to text_12: Optional style or instruction inputs

    Output:

    • text: Combined or selected text based on mode.

    5. AI4ArtsEd Random Instruction Generator

    β†’ Generates four creative, symbolic, or surreal instruction phrases to be used as part of prompt contexts.

    Input:

    • text (STRING) – typically a core concept or message

    Outputs:

    • instruction_1 to instruction_4 (STRING)

    6. AI4ArtsEd Random Artform Generator

    β†’ Generates four culturally or stylistically distinct reinterpretation prompts, suitable for LLM context use.

    Input:

    • text (STRING)

    Outputs:

    • artform_1 to artform_4 (STRING)

    7. AI4ArtsEd Random Language Selector

    β†’ Selects 12 random languages from a curated list including both major and marginalized world languages, suitable for translation-based workflows such as stille_post.

    Input:

    • (none)

    Outputs:

    • language_1 to language_12 (STRING): Language names selected from a diverse set of model-supported languages (including Yoruba, Māori, Guarani, etc.)

    πŸ” API Key Configuration (OpenRouter)

    1. Manual: Enter API key in the api_key input field (masked).
    2. File-based: Create openrouter.key in this node folder with your key on one line.

    .gitignore ensures this key is not versioned.
