Additional Korean voicebanks were expected to release some time in 2017, however, it had since been pushed back. She was announced to have an English voicebank, but it would not be in development until after the additional voicebanks have released.
Her name is derived from the word "Universe", thus dubbing her as the "Universal VOCALOID". It is pronounced /ju:ni/.
Her appearance is based off her concept of being the "Universal VOCALOID". She has a star under her left eye, as well as star badges on her tie, cuff links, and ankles.
UNI's concept plays off of electronic controls and is inspired by SeeU's design. Her skirt lights up when she sings. She wears a band on her thigh that has rewind, pause, and skip buttons. UNI's name is printed on her shoulder, based off of the Crypton VOCALOID characters' and SeeU's tattoos.
UNI's color scheme was chosen to compliment SeeU's, which is why her hair and base color were set as pink when she was first being developed.
On December 1, 2017, ST MEDiA published their first album: I Love Moonlight. The album was a compilation of all of UNI's promotional demo songs in addition to four songs made exclusively for it. A limited edition version was also produced and came with a special LED lightstand based off of the album's cover art. A five-day preorder sale was held prior to the album's release and allowed customers to purchase the normal version at a 10% discount for either respectively.

Black Shock Box
In December 2014, concept art of UNI's first design was revealed. The initial reactions were mixed, though there were several comparisons made by both Western and Korean fans that the design mirrored Hatsune Miku Append too much. Although the Korean fandom responded more positively in comparison, there was enough concern that the design should be altered.
Following the reveal, Dr. Yun wrote an announcement that the revealed design was not meant to be final nor that it was meant to be shown at all. The concept was one of several that were being worked on and UNI's final design was still in development. However, he did note the fans' concerns and would "keep them in mind" during continued development.
In August 2015, the final design for UNI was revealed. The reaction was notably more positive towards the new version with a wave of support for UNI from the Korean fans. 
After UNI's release, there was a notable growth in the Korean fandom. Her release saw the return of formerly retired producers as well.
Several of her demos surpassed 100,000 views on YouTube, as well as a number of original songs produced.
