K-Pop’s AI Revolution: Lee Soo-man’s A2O Double Debut

The short version: On October 12, 2026, Lee Soo-man — the founder of SM Entertainment and the producer who built the modern K-pop idol system — returned to the Korean music industry after a three-year non-compete and launched two groups at once: 15-member boy group A2O SOUL and 9-member girl group A2O LITE. Both debut singles, “SUPERSTAR” and “NEON,” dropped October 13 at 6 PM KST. The centerpiece of his pitch wasn’t just the music — it was 4D Gaussian Splatting (4DGS), a volumetric video technique that records a performance from every angle at once, so viewers can replay it from angles no camera ever occupied. Meanwhile, his old company SM is pushing its own AI bet: naevis, a virtual idol with an AI-synthesized voice who debuted in 2024. Two competing visions of K-pop’s AI future.

In this guide, we break down kpop tech revolution sm in plain English — what it is, how it works, and how to use it.

Kpop Tech Revolution Sm: What just happened? A2O’s double debut, explained

On October 12 at 4 PM KST, A2O Entertainment held its global debut showcase, “WELCOME TO SOULITE From A2O SOUL A2O LITE,” at KINTEX in Goyang — Lee Soo-man’s first official public appearance in Korea in about two and a half years, allkpop reports. The essentials:

• A2O SOUL — 15-member boy group, debut single “SUPERSTAR.”
• A2O LITE — 9-member girl group, debut single “NEON.”
• Both are multinational acts of teenagers from South Korea, China, Japan, Thailand, and the U.S., sharing one fictional universe built to allow future units, solos, and other projects, per Zapzee.
• Both singles released October 13 at 6 PM KST; promotions began October 8 with social channels and an Mnet “M Countdown” teaser.

Notably, both groups performed in simple, understated styling — the focus stayed on choreography. Lee’s message was old-school at heart: “As long as a K-pop group is called a singer, the most important starting point is the song.”

Who is Lee Soo-man, and why does his return matter?

Lee Soo-man is the closest thing K-pop has to a founding father. He established SM Entertainment in 1995 and led it for 28 years, building the trainee-and-idol system that became the industry’s blueprint and developing acts across four generations: H.O.T., Girls’ Generation, EXO, NCT, and aespa, notes Music Business Worldwide.

In early 2023, during a battle for control of SM, Lee sold his shares to HYBE. The deal included a three-year non-compete barring him from entertainment management in South Korea; it expired in February 2026. In the interim, A2O debuted the group A2O MAY in China in 2024 — but SOUL and LITE are his first domestic idol projects since leaving SM, allkpop reports.

Lee has always paired pop with technology. At the showcase he revived his “Culture Technology” (CT) concept — the idea of connecting emerging technologies with culture, or inventing the technology if it doesn’t exist — saying he had spent 16 years thinking about the harmony of art and technology, per SBS Star.

What is 4D Gaussian Splatting — and what does it do for K-pop?

Definition: 4D Gaussian Splatting (4DGS) is a video-capture technique that films a moving scene with many synchronized cameras at once, then reconstructs it as thousands of tiny 3D “splats” — colored ellipsoids — that move and deform over time. Because the full volume is recorded, viewers can replay a performance from any angle — even ones no physical camera occupied. The A2O showcase even included an XR experience zone built with 4DGS, K-POPIT notes.

Lee’s framing: 4DGS records “space with data from the time the artist existed and from various viewpoints” — “the camera has changed from one that films to one that creates.” The idea is concerts and music videos you can rewatch from any perspective, preserved as navigable 3D data: “what to record and what to leave for the future.”

The tech is already entering mainstream production. Framestore used 4D Gaussian Splatting in the 2025 film Superman, with a 192-camera rig capturing performances as volumetric data so directors could re-frame actors from new angles after the shoot, reports Superman Homepage. In short: 4D adds time to static 3D capture — the hologram-style, free-roaming volumetric video people have imagined for decades, CineD explains.

Meanwhile at SM: who is the AI idol naevis?

While Lee bets on real artists plus futuristic cameras, his former company is betting on artists who aren’t real at all. naevis is SM Entertainment’s first virtual artist: her voice is AI-synthesized from voice-actor samples, and her visuals are made with LG Uplus using its generative-AI product ixi-Gen, per Wikipedia.

She first appeared in 2020 as a character in aespa’s fictional universe before debuting as a standalone artist on September 10, 2024, with the single “Done,” which drew over 590,000 YouTube views in its first 17 hours, Aju Press reported. SM plans to expand her universe through webtoons, games, and brand deals — stories leaping between media, as Dungeon Crawler Carl TV Series: Everything We Know also explores.

naevis is run by Studio Realive, an SM subsidiary (founded 2022 as Studio Kwangya, rebranded 2023). Its CEO, Jay Kim, has been candid about the hard part: “With naevis, I feel that the idea, ‘We can make a real-life-like virtual artist,’ came before the question, ‘How can she communicate with fans as an artist?'” he told the Korea JoongAng Daily. Technology can create an idol — but can it create the relationship between idol and fan?

Why is K-pop betting so big on AI?

The pattern is bigger than one debut. A2O also launched its own fan platform, BloomingTalk, with interactive live features coming, Zapzee reports. SM is building AI voices and AI content pipelines.

K-pop has always been a technology business disguised as a music business — the trainee system was human R&D; the synced-lightstick arena was hardware. AI and volumetric video are the next iteration. The open question remains Studio Realive’s: the tech works, but does the fandom follow?

What should fans watch next?

• The music: “SUPERSTAR” and “NEON” are out — the real test of whether the songs match the tech spectacle. (Wondering how platforms handle brand-new releases? See Why Shows Leave Streaming Services: Stay-or-Go Decisions.)
• The 4DGS content: volumetric music videos and XR experiences — the first test of whether fans want any-angle performances.
• BloomingTalk: A2O’s fan platform is adding interactive live features.
• The shared universe: SOUL and LITE inhabit one fictional world with room for units and solos — watch how it’s told, and who owns it (see Why Hunger Games Is Leaving Netflix: Rights Explained).

Frequently asked questions

What is 4D Gaussian Splatting?

4D Gaussian Splatting (4DGS) is a volumetric video technique that records a moving scene with many synchronized cameras and reconstructs it as thousands of tiny moving 3D “splats,” creating a navigable 3D recording viewers can replay from any angle. Lee Soo-man made it the technological centerpiece of A2O Entertainment’s October 2026 debut of A2O SOUL and A2O LITE.

Who are A2O SOUL and A2O LITE?

A2O SOUL is a 15-member boy group and A2O LITE is a 9-member girl group, launched simultaneously by Lee Soo-man’s A2O Entertainment on October 12, 2026. Both are teenagers from South Korea, China, Japan, Thailand, and the U.S., share a fictional universe, and released “SUPERSTAR” and “NEON” on October 13, 2026.

Is naevis a real person or an AI?

naevis is not a real person. She is SM Entertainment’s first virtual artist: her voice is AI-synthesized from voice-actor samples and her visuals are created with generative AI in partnership with LG Uplus. She first appeared in aespa’s fictional universe in 2020 and debuted as a solo virtual artist on September 10, 2024, with the single “Done.”

Why did Lee Soo-man leave SM Entertainment?

In early 2023, during a battle for control of SM Entertainment, Lee Soo-man sold his shares to HYBE. The deal included a three-year non-compete barring him from entertainment management in South Korea; it expired in February 2026, after which he returned with A2O Entertainment’s domestic debut projects.

Will AI replace human K-pop idols?

Not according to the industry’s own experiments. A2O is betting on human artists enhanced by capture technology like 4DGS, while SM’s virtual idol naevis has struggled to build the core fandom human idols attract — For now, AI looks like a powerful production tool and a side-stage experiment, not a replacement for real performers.

What is Culture Technology (CT)?

Culture Technology is Lee Soo-man’s long-running concept for how K-pop should relate to technology: not just adding tech to music, but studying emerging technologies, connecting them with culture, and inventing new tools when they don’t exist. At A2O’s October 2026 debut, he said he had spent 16 years thinking about the harmony of art and technology.
