Responsibilities

This project contains code adapted from:

| Original project | Author | Licence | Adapted files | |-------------------|-------|----------|-------------------| | EA_LMStudio | EnragedAntelope | MIT | node_lm_studio.py, node_llm_unload.py, _model_fetcher.py, _config_manager.py | | ComfyUI_Steudio | Steudio | GPL v3 | node_dac_algorithm.py, node_divide_image_select.py, node_combine_tiles.py, node_dac_data_scale.py, node_display_ui.py, js/steudio/ | | ComfyUI-Photopea | coolzilj | MIT | js/photopea/ |

| Node | Subcategory | Description | |------|-------------|-------------| | LM Studio 988 | 🦇988/LM Studio | Text generation using local LLM/VLM models via LM Studio server. Supports vision (multi-image), reasoning extraction (DeepSeek, Qwen, QwQ, GLM, GPT-OSS), draft models for speculative decoding, and system message templates. | | LM Unload 988 | 🦇988/LM Studio | OPTIONAL Passthrough node that unloads LLM models from LM Studio and/or clears ComfyUI VRAM. | | DaC Algorithm 988 | 🦇988/Image | Calculate optimal upscale dimensions while maintaining minimum tile overlap and scale factor constraints. Optionally upscale with a model before tiling. | | Divide Image Select 988 | 🦇988/Image | Divide the upscaled image into tiles using coordinates from DaC Algorithm. tile=0 returns all tiles, tile=N returns a single tile. | | Combine Tiles 988 | 🦇988/Image | Combine processed tiles back into a single image using Gaussian-blurred overlap masks for seamless blending. | | DAC Data Scale 988 | 🦇988/Image | Scale all DAC_DATA dimensions (width, height, tile, overlap) by a multiplier. Grid and tile order are preserved unchanged. | | Ratio Calculator 988 | 🦇988/Image | Analyse an image and return its closest matching aspect ratio label (e.g. 16:9). | | Ratio to Size 988 | 🦇988/Image | Pick an aspect ratio and target megapixel count to get optimal width and height (multiples of 64) within a precision tolerance. | | Load Images into List 988 | 🦇988/Image | Load all supported image files from a directory into a batch tensor. Supports jpg, jpeg, png, webp. | | Seed Shifter 988 | 🦇988/Number | Generate a batch of reproducible seeds from a base seed + offset. Each seed = base + offset + index. | | Sequence Generator 988 | 🦇988/Number | Generate a sequence of numbers. Syntax: x...y+z (step), x...y#z (evenly spaced), x,y,z (literal list). | | Simple Config 988 | 🦇988/Utility | Select a sampler and scheduler to pass their string values as individual outputs. | | Display UI 988 | 🦇988/Utility | Display any input value as a read-only text box on the node. Accepts strings, numbers, or any wire type. | | Pipe IN 988 | 🦇988/Utility | Bundle up to 10 signals of any type into a single PIPE. Autogrow inputs — shows connected + 1 slots (min 1), expands up to 10 as you connect. Auto-detects type from the connected source and repaints the socket label + colour accordingly. Pipe pass-through — an incoming PIPE provides defaults for all slots; individual inputs override. | | Pipe OUT 988 | 🦇988/Utility | Unpack a PIPE back into individual signals. All 10 signal sockets are always shown (indices 0–9 stable across saves). Sockets are auto-labelled with the original signal name and coloured by type via traceback through the Pipe IN node. Tunnels through any intermediate pass-through nodes (not just Pipe IN/OUT). Last socket is a PIPE passthrough for chaining. Includes a ↻ refresh button and context menu item for manual re-sync. |
