Researchers have introduced Archon, a novel unified multimodal model designed for the holistic generation of digital humans. This model integrates seven distinct modalities, including text, audio, motion, and visual content, through modality-specific tokenizers and an autoregressive architecture. Archon was pretrained on synchronized modalities and 72 diverse tasks to effectively model joint distributions. To manage the complexity of high-fidelity talking videos, the system employs a memory-efficient semantic video reparameterization that reduces token count by 4x while preserving dynamics, complemented by a semantic-driven video diffusion decoder. Furthermore, a "Thinking in Modality" approach decomposes ambiguous cross-modal tasks into sequential steps, enhancing fidelity and controllability. AI
