Topaz LabsImage UpscaleGigapixel High Fidelity 3
Gigapixel High Fidelity 3 (also known as High Fidelity v3) is a proprietary precision image-upscaling model developed by Topaz Labs. It was introduced in 2026 as an update to the High Fidelity model family for medium- and high-quality source images.
High Fidelity 3 is intended to enlarge already detailed photographs while preserving original structure, natural texture, grain, and noise. Compared with the previous version, Topaz describes improved detail retention and reduced repetitive or plasticky-looking artifacts. It is suited to modern photographs, RAW images, and other images where preserving the original character is important.
