What is Qwen 3 4b?
Qwen 3 4b is a text encoder that converts prompts into embeddings used to guide generation. You can run it locally in ComfyUI with full control over every parameter, or access it through Comfy Cloud. ComfyUI's node-based workflow editor lets you connect Qwen 3 4b with ControlNets, LoRAs, upscalers, and custom nodes to build any pipeline you need. There are 21 community workflow templates using Qwen 3 4b on Comfy Workflows, ready to load and customize.
