Topaz Labs Gigapixel AI version 5.8 released (now $20 off)

Topaz Labs released Gigapixel AI version 5.8 with several improvements, including better face refinement and increased speed when upscaling and enhancing images.

The new Topaz Labs Gigapixel AI is now $20 off until February 18 (you can use coupon code RUMORS15 for an extra 15% off).

Here is what's new in Gigapixel AI version 5.8:

  • Improved face refinement pipeline – Gigapixel AI will now do a much better job detecting human faces more often and delivering more realistic results. Tiny background faces especially should see a noticeable improvement in quality.
  • Significant image quality improvements with Windows GPU – You’ll notice much better image quality across all models in Gigapixel AI when using GPU-powered Windows machines.
  • Reduced memory usage – We’ve streamlined how we cache and utilize image data through the entire editing pipeline, resulting in less memory usage and faster importing and exporting of image files.
  • Lots of usability improvements and bug fixes – We’ve improved the post-processing resize algorithm, optimized how we compress JPG, PNG, and TIFF files when exporting, and squashed a bunch of annoying bugs.
