image-outpainting
Image outpainting on RunComfy via the `runcomfy` CLI — extend a still beyond its original canvas, fill in what the camera didn't capture, change aspect ratio (square → 16:9, portrait → landscape) while preserving the original content. Routes across Nano Banana 2 Edit (default, spatial-language driven), GPT Image 2 Edit (multi-ref with reference-style matching), FLUX Kontext Pro (single-shot maximum-preservation), and the brand edit endpoints (Seedream / Dreamina / Qwen / FLUX 2). Picks the right route based on whether the outpaint is prose-driven, reference-driven, or brand-locked. Triggers on "outpaint", "outpainting", "extend image canvas", "expand the image", "fill in around the photo", "uncrop", "change aspect ratio", "extend frame", "wide-screen from square", or any explicit ask to add canvas around an existing still.
Why this skill is useful
Adds specific commands and routing logic for image outpainting using the RunComfy CLI that the AI wouldn't generate on its own.

What this skill does
Image Outpainting Extend a still beyond its original canvas — uncrop, change aspect ratio, fill in what the camera didn't capture. This skill routes across the identity-preserving edit endpoints in the RunComfy catalog, picking the right one for prose-driven extension, reference-style matching, or brand-locked continuation. runcomfy.com · best-image-editing-models · CLI docs Powered by the RunComfy CLI CLI deep dive: runcomfy-cli skill. --- Pick the right model Listed by suitability for outpainting workflows. Nano Banana 2 Edit — google/nano-banana-2/edit (default for prompt-shaped outpaint) Identity-preserving edit; honors spatial language ("extend the canvas to the left and right by ~30%", "add sky above the building"). The result is a wider canvas with the original content preserved. Pick for: aspect-ratio change (square → 16:9), uncrop a portrait, extend a landscape photo with matching environment. Avoid for: pixel-precise extension matching texture seams — use a ComfyUI outpainting workflow. GPT Image 2 Edit — openai/gpt-image-2/edit Up to 10 reference images, layout-precise instruction following. Useful when outpainting needs to match a reference style or includes layout repositioning. Pick for: composite outpaint (extend canvas + paste in element from another image), layout repositioning during the canvas change. Avoid for: simple outpaint without external references. FLUX Kontext Pro — blackforestlabs/flux-1-kontext/pro/edit Single-instruction, high-preservation edit. Use form: "Extend the canvas to a 16:9 aspect ratio. Add matching sky and architecture continuing from the existing scene. Keep everything in the original image exactly." Pick for: single-shot outpaint with maximum preservation of the original content. Seedream / Dreamina / Qwen / FLUX 2 edit endpoints Brand-specific edit endpoints (bytedance/seedream-5/lite/edit, bytedance/dreamina-4-0/edit, qwen/qwen-image/qwen-image-edit-2511, blackforestlabs/flux-2-pro/edit, etc.). …
