Gigapixel: Comparing upscaling models with AB test

Demo summary

The user demonstrates the AB compare tool in Topaz Gigapixel AI to evaluate the 'Standard V2' versus 'High Fidelity V2' models on skin and hair textures.

Step-by-step

  1. Open the models menu
  2. Click the AB compare tool icon
  3. Select 'Standard V2' for the left preview and 'High Fidelity V2' for the right preview
  4. Use the magnification slider to zoom in on fine details like hair and skin pores
  5. Pan around the image to compare textures between the two models
  6. Click 'Apply Model' on the preferred version to update the image

Options

  • Use the Low Res model for images with heavy artifacts or JPEG compression
  • Adjust magnification without affecting the final upscaling size

Watch out for

  • One model is not always superior to the other; performance varies from image to image even within similar types

Tips

  • Avoid sticking to a single favorite model as results vary per generation
  • Compare how models handle fine details like hair and pore texture to make your selection
  • If a model looks slightly too sharp, consider a more natural-looking alternative
  • Choose a more natural model (like High Fidelity) if you plan to add custom sharpening later in a photo editor

Highlights

it's easy to just get bugged down in what your favorite one is... so I like to use this AB compare tool
