Topaz Labs Gigapixel AI version 5.8 released, currently on sale

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

The Gigapixel AI software lets you upscale photos up to 600%.

The new Topaz Labs Gigapixel AI is now $20 off until February 18 (you can use coupon code RUMORS15 to get an additional 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.
