IITERNITI is an AI-based virtual idol group that produces music centered on emotions and relationships. The album HELLO WORLD is themed around “AI’s first greeting to the world” and expresses the moment when AI and humans connect through emotion.

The album spans a spectrum of genres, from bright teen pop to epic pop, energetic EDM, and funky unit tracks, showcasing IITERNITI’s diverse musical appeal. The project features Puls Nine’s Deep Real AI technology and contributions from AI sound engineer Ha Su-ho, composer Doodeumbeom, Park Chan-jae, Lee Ju-heon, and vocalist Lee Songhwa, among others.

The title track Hello World is described as an easy-listening pop song that marks IITERNITI’s new beginning as “your friend, an AI idol.”

Before the official release, the HELLO WORLD PREMIRE preview showcase was held at a Hongdae flagship store, where IITERNITI performed live and shared behind-the-scenes stories, and attendees watched portions of the music video created through human–AI collaboration.

Park Ji-eun, CEO of Puls Nine, stated that “IITERNITI’s HELLO WORLD is not just an AI project, but a record of understanding human emotion and art and growing together,” and that “through this album, AI idols will evolve from listening subjects into beings that tell stories and connect.”
