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.

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.). …
