Topaz Labs has released Gigapixel AI 6.0, the latest version of its AI-trained software for increasing the resolution of photos or rendered images without softening or introducing noise into the result.
The update adds native support for Apple’s M1 processors, reducing processing times on M1 Macs by around 40%; and added an optimised 16-bit version of its Standard AI model to improve performance on Windows.
Full disclosure: the update was actually released last month, but we didn’t manage to cover it at the time.
Machine-learning-trained tool enlarges images without sacrificing detail
Gigapixel AI is designed to enlarge digital images while preserving their sharpness, using machine learning techniques to fill in the missing details.
Its algorithms are trained using a data set of “millions of photos of all subjects and styles”, and can enlarge photos by “up to 600%” before image quality starts to drop visibly.
The software supports batch processing, making it possible to run it on entire image libraries.
Works for renders as well as photos
Although it’s marketed primarily at photographers, Gigapixel AI can also be used on rendered imagery – and, as of Gigapixel 5.3, has a dedicated AI mode for CG images and scanned artwork.
As well as simply upscaling low-res renders to generate high-res images more quickly, it can be used to remove residual noise from renders by upscaling them in Gigapixel, then reducing them to their original size.
New in Gigapixel AI 6.0: native support for Apple M1 processors
The main change in Gigapixel AI 6.0 is native support for Apple’s M1 processors.
According to Topaz Labs’ blog post, native M1 support cuts software startup times by 47% over Rosetta emulation, previously used on new Macs; and cuts image batch processing times by 44%.
The update also introduces optimised 16-bit backends for the software’s Standard AI model, which should improve performance on Intel Macs, and on Windows machines processing images on the GPU.
Workflow and UX improvements include increased tonal and colour contrast in the UI; and users now have the option to download all of its AI models on installation, to remove the need for manual downloas later.
Pricing and system requirements
Gigapixel AI 6.0 is available as a standalone application for Windows 10+ and macOS 10.14+; and as a plugin for Photoshop and Lightroom Classic, on both Windows and macOS. New licences cost $99.99.
The software is OpenGL-based, so it should work on any manufacturer’s hardware, but requires a reasonably powerful GPU.
