Image Super Resolution

Use SeedVR2 to restore low-resolution, compressed, or mildly blurred images and enhance fine details while preserving the original content and composition. It is suitable for restoring older assets, repurposing content, and preparing high-resolution deliverables.

Typical Application Scenarios

• Low-resolution restoration: Reduce compression artifacts, mild blur, and missing fine details.
• Content enhancement: Upgrade older or small-format assets for high-resolution presentation.
• Workflow preprocessing: Improve source-image quality before image editing or 3D reconstruction.

Best Practices

TIP

• Only the seedvr2 model is currently supported.
• Use an image with a recognizable subject and no severe occlusion. Super resolution can enhance existing details but cannot reliably reconstruct content that is entirely missing.
• Inputs may be a returned asset_path, Base64 image data, or a publicly accessible HTTPS URL.
