ComfyUI-LLMs-Toolkit

ComfyUI custom nodes for DeepSeek, Qwen, GPT, and other OpenAI-compatible LLM APIs, with built-in tools for chat, translation, vision, and JSON workflows.

What is this?

ComfyUI-LLMs-Toolkit is a ComfyUI custom node pack for connecting DeepSeek, Qwen, GPT, Moonshot, and other OpenAI-compatible LLM APIs directly inside ComfyUI workflows.

Use it to build LLM-powered ComfyUI workflows for prompt generation, translation, structured JSON output, image understanding with multimodal models, and other text or vision automation tasks without running a local GPU model.

Key Features

• Built-in Provider Manager — Manage all your API providers visually from ComfyUI's menu bar. No config files to edit.
• 12 Providers Pre-configured — Qwen, DeepSeek, GLM, Doubao, Spark, Moonshot, Baichuan, MiniMax, StepFun, SenseChat, iFlow, ModelScope.
• Smart Model Dropdown — Select a provider, and the model list updates automatically.
• Vision Support — Send images to multimodal LLMs with the Image Preprocessor node.
• Won't Crash Your Workflow — If an API call fails, you get a readable error message instead of a broken workflow.
• Multi-turn Memory — Enable conversation memory for chat-style interactions.
