This ComfyUI workflow turns Qwen 3.0 (4B, Thinking variant) into a drop-in text generator you can run inside a node graph. It loads the Qwen3-4B-Thinking weights with CLIPLoader, feeds your prompt and decoding settings to TextGenerate, and displays the final text in PreviewAny for quick copy-out. A MarkdownNote node is included in the graph with usage tips so you can remember the key parameters at a glance.

Under the hood, TextGenerate performs standard autoregressive decoding with adjustable parameters like temperature, top_p, and max new tokens. CLIPLoader is used here to point ComfyUI at the Qwen 3.0 text encoder weights (qwen_3_4b.safetensors) stored in models/text_encoders. The result is a compact, reproducible setup for generating detailed, reasoned responses, ideal for drafting explanations, outlining ideas, and iterating on prompt engineering directly in ComfyUI. As of 2026/03, ComfyUI supports the 4B Qwen 3.0 model for this workflow.
