SemiGraph Raises Over $10 Million for Daihao Live, a 3D AI Idol Game Starring Ria

SemiGraph is developing Daihao Live (代号Live), a 3D virtual idol interaction and character-growth project centered on a girl named Ria. Players take the role of her producer, accompanying her through conversation, performances and a relationship intended to evolve over time.

The Shanghai-based company has also completed a new funding round of more than US$10 million. More importantly for the product itself, SemiGraph is attempting to move beyond text-only AI by allowing a 3D character to respond with voice, expressions, body movement and relationship-aware behavior.

Ria and 3D AI Interaction

Players Become Ria's Producer

Daihao Live places the player beside Ria as her producer. Rather than functioning only through dialogue choices, the concept revolves around following a rookie idol who can sing, dance, train and interact continuously.

SemiGraph identifies character growth and real-time AI interaction as the product's core foundation. Training decisions and the relationship with the player can influence how Ria develops.

The Relationship Is Designed as One-on-One

SemiGraph wants each player to feel that their relationship with Ria belongs specifically to them.

Conversation history, habits, previous interactions and relationship state can shape future responses. The aim is to make Ria feel less like a 3D avatar cycling through fixed animations and more like a persistent character whose behavior remains connected over time.

AI Drives Expressions and the Body, Not Just Text

SemiGraph's official material shows AI being used to generate movement and facial expressions, while character models and environments remain part of a high-quality 3D pipeline.

The company describes its broader goal as giving AI a visible form and embodied behavior. Voice, gesture, posture, expression and contextual reactions therefore matter alongside language-model responses.

From Lumi to Ria

SemiGraph founder Xing Jun previously worked on AI research at miHoYo, including technology connected with the virtual character Lumi.

At SemiGraph, that background has been redirected toward a more interactive product. Ria is intended not only to perform as a virtual idol but to grow alongside players and form a different relationship with each user.

New Funding Expands SemiGraph's 3D AI Work

SemiGraph has completed a new funding round worth more than US$10 million. The money is intended for human behavior model development, data infrastructure, team expansion and bringing AI-native 3D interaction into products.

Daihao Live also serves as a practical test of whether that technology can create an appealing long-term character experience rather than functioning only as a technical showcase.

Why This Matters

1) AI is integrated directly into the relationship mechanics

It is not limited to extra dialogue generation; movement, expression, voice and contextual response all form part of the interaction.

2) Ria is designed to grow

The player acts as producer, connecting character development and relationship-building to the core experience.

3) Each player is meant to receive a different experience

SemiGraph emphasizes personalized one-on-one interaction rather than one generated experience shared by all users.
