LPM 1.0 enables real-time character performances

LPM 1.0 is a breakthrough for digital humans, moving beyond simple talking heads to "full-duplex" interactive actors that can listen and react in real-time.

• –Addresses the "performance trilemma" by balancing high expressiveness, real-time inference, and long-horizon identity stability.
• –Novel interleaved audio injection processes speaking and listening audio in separate layers to distinguish lip movements from micro-expressions.
• –Base 17B model is distilled into a causal streaming generator ("Online LPM") for low-latency, infinite-horizon interaction.
• –The system supports multimodal control, unifying text prompts, audio signals, and reference images for professional-grade identity preservation.
• –Includes LPM-Bench, a first-of-its-kind benchmark for standardizing the evaluation of interactive character performance quality.
