Model Selection

We recommend starting with what you are trying to do, then selecting the best model from there.

Image

Upscale an Image

Three tiers, each with a different tradeoff:

	Gigapixel	Wonder	Bloom
Tier	Precision	Generative	Creative
Description	Precision Image Upscale & Enhancement	Generative Image Upscale & Enhancement	Creative Image Upscale & Enhancement
Intent	Improve resolution, preserve source characteristics.	Improve and restore by adding detail and texture, while preserving intent.	Transform with new, creative detail or stylization.
Use Case	General purpose upscaling & enhancement.	Upcaling, restoring and improving low resolution or compressed sources.	Upscaling, improving, and transforming GenAI sources.

Gigapixel

Model	Use Case
Standard 2	Default — works for most images
High Fidelity 2	Maximum source preservation
Low Resolution 2	Very small inputs (thumbnails, web scrapes)
Art & CGI	Illustrations, renders, game assets, digital art
Text & Shapes	Documents, screenshots, text-heavy images
Recover Faces	Portraits where facial detail is the priority
Transparent Image Upscale	PNGs with alpha channels

Wonder

Model	Use Case
Standard Max	Default generative upscaling
Wonder 2	Stronger generation for more detail
Redefine: Realistic	Generative enhancement grounded in photorealism
Redefine: Creative	Generative enhancement with more creative freedom
Recover 3	Heavily degraded or damaged sources

Bloom

Model	Use case
Bloom Creative	Maximum stylization
Bloom Realism	Creative but more grounded

Sharpen or Deblur

Standard — use when you know the blur type:

Model	Use case
Sharpen	General-purpose — good starting point
Sharpen Strong	Noticeably soft images
Sharpen Natural	Subtle sharpening that avoids over-processing
Sharpen Lens Blur 2	Optical blur from lens softness or missed focus
Sharpen Motion Blur	Blur from camera or subject movement
Sharpen Refocus	Slightly out-of-focus images
Portrait	Optimized for faces and skin texture
Wildlife	Optimized for fur, feathers, scales

Generative — use when the source is heavily degraded or you're unsure of the blur type:

Model	Use case
Super Focus 2	Generative sharpening that recovers detail beyond the original

Reduce Noise or Grain

Pick based on noise severity:

Model	Use case
Denoise Normal	Light noise — well-lit conditions
Denoise Strong	Moderate noise — high ISO, low light
Denoise Extreme	Heavy noise — very high ISO, underexposed
Dust & Scratch 2	Film scans or archival images with physical artifacts

Remove Objects or Backgrounds

Model	Use case
Background Removal	Remove the background entirely
Image Object Matting	Extract subject with transparency for compositing

Correct Color or Lighting

Model	Use case
Balance Color	Auto white balance and color correction
Adjust Lighting 2	Exposure and contrast adjustment
Image Colorization	Convert black-and-white to color

Video

Upscale or Enhance a Video

Three families, each with a different tradeoff:

	Proteus	Starlight	Astra
Tier	Precision	Generative	Creative
Description	Precision Video Upscale & Enhancement	Generative Video Upscale & Enhancement	Creative Video Upscale & Enhancement
Intent	Improve resolution, preserve source characteristics.	Improve and restore by adding detail and texture, while preserving intent.	Transform with new, creative detail or stylization.
Use Case	General purpose upscaling & enhancement.	Upcaling, restoring and improving archival and GenAI	Upscaling, improving, and transforming GenAI sources.

Proteus

Don't know where to start? Use Proteus. Then narrow down if your source has specific characteristics:

Model	Use case
Proteus	Default — handles most content well
Proteus Natural	Lighter processing, stays closest to the original
Artemis HQ / MQ / LQ	Match to your source quality — HQ for clean footage, LQ for degraded
Artemis Aliasing/Moire	Visible aliasing or moire patterns
Artemis Medium Halo / Strong Halo	Halo artifacts from older upscaling or edge enhancement
Dione TV / DV	Interlaced broadcast (TV) or camcorder (DV) footage
Dione Robust	Interlaced content with heavy degradation
Dione Dehalo / Robust Dehalo	Interlaced content with halo artifacts
Gaia 2 (Animation)	Animation and single-frame animation
Gaia HQ / CG	High-quality or general CG and rendered content
Iris MQ / LQ	Legacy content at medium or low quality
Rhea	General enhancement with natural texture
Theia Fine Tune Detail	Push detail enhancement — more aggressive
Theia Fine Tune Fidelity	Preserve original look — lighter touch

Starlight

Quality and Fast subtiers. Use Quality when output matters most, Fast when speed or cost is the priority.

Model	Subtier	Use case
Starlight HQ	Quality	Maximum quality generative output
Starlight Precise 2	Quality	Default for most generative work
Starlight Precise 1	Quality	Highest fidelity to source
Starlight Sharp	Quality	Emphasis on sharpness and edge detail
Starlight Fast 2	Fast	Best fast model — start here for speed
Starlight Fast 1	Fast	Speed-optimized generative enhancement
Starlight Mini	Fast	Lightest — previews or cost-sensitive jobs

Astra

Model	Use case
Astra Creative	Creative video transformation

Reduce Noise or Grain

Denoise

Quality and Fast subtiers via the Nyx family:

Model	Subtier	Use case
Nyx	Quality	Default — balanced noise reduction and detail
Nyx XL	Quality	Stronger reduction for heavy noise
Nyx High Fidelity	Quality	Maximum detail preservation, lighter reduction
Nyx Fast	Fast	Speed-optimized denoising

Change Frame Rate or Create Slow-Mo

Frame Interpolation
