ComfyUI Tutorial Series: Mastering Stable Diffusion AI - ComfyUI Tutorial Series Ep 66: Qwen Outpainting Workflow + Subgraph Tips

In this episode of our ComfyUI tutorial series, we explore AI outpainting using the Qwen Outpainting Workflow and share subgraph optimization tips to make your workflows cleaner. You’ll learn how to extend images beyond their original borders, add new background details, and create wide shots, all directly inside ComfyUI using the Nunchaku Qwen model. This tutorial also walks through installing required models and nodes, configuring your GPU for Int4 or FP4 models, and simplifying complex node setups into compact subgraphs for efficient editing and reuse. Whether you’re expanding landscapes, completing portraits, or optimizing your workflows, this episode covers every step in detail, from setup to output.
