Her voice was created by taking vocal samples from singer Megumi Nakajima at a controlled pitch and tone.

On December 11, 2010, the president of Internet Co. announced that Gackpoid, Megpoid, and Lily would be distributed in Taiwan.

[2] On October 21, 2011, a new version of the software, called "V3 Megpoid", was released containing a package of four different tones of GUMI's voice for Vocaloid 3: Adult, Power, Sweet, and Whisper.

This was originally going to be an expansion pack for the Vocaloid 2 version of GUMI under the name of "Megpoid Extend" and was based on the "Append" vocals of Crypton Future Media.

On February 28, 2013, another new version of GUMI, called "Megpoid English" was released also for the Vocaloid 3 engine.

In mid November 2023, it was announced that GUMI would be receiving a software release for Synthesizer V, also called AI Megpoid.

Gumi initially struggled to build popularity against the Crypton Future Media's Character Vocal series and was considered to be "nothing special" when first released.

In 2011, her usage grew and in a number of weeks she would have even more songs in the top 100 rankings than some of the Crypton Future Media vocalists.

The released titles include Mozaik Role, Kiritorisen, Shiryoku Kensa, Setsuna Trip, Ringo Uri no Utakata Shoujo, and Yowamushi Montblanc.

This features the fictional birth story of "Gumi", who was a girl who becomes an Android and debuts as an idol.

The story focuses on her and a mysterious team called Interface sound Orchestra (インタネ団).

Masanori Okamoto is responsible for many aspects of this project including the script and filming of the short.

[17] She also appears as a special guest in several songs in Hatsune Miku and Future Stars: Project Mirai and its sequel.
