What is LPM? A Deep Dive into miHoYo's AI Character Performance Model
What is LPM?
LPM (Large Performance Model) is a revolutionary AI video character performance generation model released by miHoYo's AI team (led by Cai Haoyu) on April 10, 2026.
It's not just another AI video generation tool — LPM fundamentally redefines how we interact with virtual characters through AI.
Six Core Breakthroughs
1. Real-time Character Video Generation
Traditional AI video generation requires minutes or even hours of rendering time. LPM achieves instant output, generating high-quality character video content without pre-rendering.
This means you can see characters react to your inputs in real-time with minimal latency.
2. Full-duplex Dialogue
LPM supports full-duplex dialogue — you can interrupt, interject, change topics, and the character responds naturally. This isn't a simple Q&A system; it's true bidirectional interaction.
This capability evokes the fluidity of real human conversation, an unprecedented breakthrough in the AI character domain.
3. Unlimited Duration Generation
Current mainstream AI video models (Sora, Runway Gen-3, Pika) have strict duration limits, typically around 10-15 seconds.
LPM breaks this limitation, supporting unlimited duration continuous generation. This is revolutionary for long-form content production, sustained dialogue scenarios, and livestreaming applications.
4. Nuanced Emotional Performance
LPM possesses human-like emotional performance capabilities. Characters can express joy, anger, sadness, subtle facial expression changes, and body language adjustments — these details truly bring virtual characters to life.
5. Identity Consistency
Maintaining character features unchanged during long video generation is a massive technical challenge. LPM uses advanced identity preservation mechanisms to ensure that even in extended videos, the character's appearance, voice, and personality traits remain perfectly consistent.
6. Multi-language Real-time Dialogue
LPM supports real-time dialogue in Chinese, Japanese, English, and more, with seamless language switching during conversation. This is a crucial feature for globalized gaming and content markets.
