SoulX-FlashHead is a 1.3B-parameter framework for high-fidelity, infinite-length, real-time streaming talking-head portrait video generation driven by audio. It includes inference code, pretrained checkpoints, a Gradio demo, and the 782-hour VividHead training dataset.

Use cases

• generate talking head videos from audio
• real-time streaming digital human avatar
• audio-driven lip sync video generation
• build a real-time virtual presenter
• infinite-length portrait video generation
• low-latency digital human interaction

When to choose

• you need real-time streaming talking-head generation on consumer GPUs
• you want high-fidelity audio-driven portrait video with no identity drift over long sequences
• you need a lightweight model (96 FPS on a single RTX 4090) for digital human applications

When to avoid

• you need full-body or multi-person video generation
• you lack a CUDA GPU, as inference requires NVIDIA hardware
• you need training code, which is not yet fully released
