What you’ll do
Match a task to the right Runflow model in under a minute.Decision tree
| Task | Reach for | Why |
|---|---|---|
| Replace a product photo background | runflow/background-replace | Preserves the foreground subject, matches new lighting. |
| Remove a background only | bria/background/remove | Cheap and fast. |
| Remove a person, sign, or logo | runflow/object-removal | Inpaint with no prompt needed. |
| Change eye color | runflow/eye-color | Targeted edit, identity-preserving. |
| Edit any image with a prompt | google/nano-banana-2/edit or black-forest-labs/flux-pro/kontext | Best general-purpose edit. |
| Generate an image from text | google/nano-banana-pro | High-quality general-purpose text-to-image. |
| Generate a video from text | google/veo3.1 or bytedance/seedance/2.0/text-to-video | veo3.1 for cinematic, seedance for speed. |
| Animate a still image | google/veo3.1/image-to-video | Image-to-video conditioning. |
| Add character to a video | heygen/v3/video-agent | Avatar-driven. |

| Upscale a photo | topaz/upscale/image | Up to 4x with detail recovery. |
Three things to check before you pick
- Pricing unit.
$/request(flat) vs$/megapixelvs$/second(video). Map to your average asset size. - Result delivery. Runs are asynchronous by default. Use callbacks or polling unless the model page documents
sync_modeand you intentionally want inline output. - Inputs. Most edit models accept either a public URL or an upload. Read the model page for required input keys.
Try one
Pick a model from the table, open its page, and copy the curl block. The samples come straight from the per-modelllms.txt and most use the literal string Bearer RUNFLOW_API_KEY rather than an env-var. Substitute your actual token before running, or change the header to Bearer $RUNFLOW_API_KEY (curl) / Bearer ${process.env.RUNFLOW_API_KEY} (Node) / f"Bearer {os.environ['RUNFLOW_API_KEY']}" (Python).
