In ComfyUI, Luma Uni-1 shows up as partner Partner Nodes for unified image work: Create graphs generate new images from prompts (with optional references); Modify graphs take an existing image as input and edit it in place. You drive both through the usual workflow: wire Load Image / Save Image, set prompts, seeds, aspect ratio, and reference slots on the Luma node, then queue the graph locally or open a template on Comfy Cloud. Luma describes Uni-1 as a non-diffusion, decoder-only autoregressive model that reasons over your prompt before drawing. On the canvas, what matters most is choosing Create vs Modify, labeling references clearly, and iterating with seeds.

​
What makes Uni-1 different

  • Two clear modes: Create Image (generate something new) and Modify Image (edit something existing)
  • Up to 9 reference images, each with a defined role
  • Strong control over niche and specific visual styles
  • Seed support for reproducibility and controlled iteration
  • Nine aspect ratios, from ultra-tall to ultra-wide
  • Text rendering that’s actually readable
  • Web search grounding for real-world context
  • Multilingual prompts
  • Multi-panel output with temporal consistency
If you understand the modes and how to control references, you understand Uni-1.

​

  • Image editing and multi-turn refinement
  • Reference-guided generation with identity preservation
  • Multi-panel output: consistent characters/scenes across multiple frames
