In the anime series Gundam Seed, the ZGMF-600 GuAIZ (pronounced "gates" in Japanese and "gwaze" in the English release) is an advanced mobile suit intended to replaced both the outdated ZGMF-1017 GINN and the commander-model ZGMF-515 CGUE. It incorporated beam weapon technology from the four stolen Earth Alliance G Project units, in the form of a beam rifle and a shield mounting a pair of beam claws. It also mounted two CIWS guns in the head and a pair of extensional arrestors on the back, which were similar to the GAT-X207 Blitz Gundam's "Gleipnir" or the GAT-X105 Strike Gundam's "Panzer Eisen" rocket anchors, which were even capable of damaging mobile suits protected with Phase Shift armor. While the GuAIZ was the most advanced mass production unit of the war, ZAFT was unable to build them quickly enough to field in sufficient numbers. Those that were produced were assigned primarily to ace pilots like Rau Le Creuset and the members of the elite Joule Team. The GuAIZ was markedly superior to the GINN and proved to be equal in performance to the Strike Gundam, however; even in the hands of a highly elite pilot like Le Creuset, it simply could not be made powerful enough to match the nuclear-powered Gundams: Freedom, Justice, Regenerate and Providence, or the Trans-Phase Armor equipped second-phase Gundams piloted by Living CPUs, deployed by the Earth Alliance, Forbidden, Calamity and Raider.

A variant of the GuAIZ was also built, the YFX-600R GuAIZ Experimental Firearms Type. This suit was built as a testbed for many of the advanced weapons and technology used in the ZGMF-X09A Justice and ZGMF-X10A Freedom Gundams, including Justice's backpack/subflight lifter and Freedom's hip-mounted railguns. While it was initially battery powered, the GuAIZ Experimental Firearms Type was lated refitted with N-Jammer Canceller technology. In addition, the YMF-X000A Dreadnought Gundam used a modified GuAIZ body.

After the end of the war, the GuAIZ was redesigned, replacing the extensional arrestors with a pair of hip-mounted folding railguns and removing the additional thrusters to allow less experienced pilots to use them; and so it became the advanced production type ZGMF-601R GuAIZ R. Though more powerful than the original GuAIZ in terms of firepower, the GuAIZ R is generally outperformed by the follow-on ZAKU series (especially ZAKUs equipped with the high-performance Blaze or Slash packs). GuAIZ R units also fared poorly against renegade GINN High Maneuver Type IIs in the Battle of Junius Seven, but it unclear whether this was a sing of inferiority on the part of the GuAIZ R, or merely on the part of the ZAFT pilots.
