What is Phoenix-4?

Phoenix-4 is Tavus’s next-generation facial-rendering and animation model that gives PALs lifelike expression and emotional realism. Built with a 3D Gaussian-diffusion system, it generates subtle, humanlike micro-expressions and head movements that sync perfectly with speech in real time. This lets your PAL smile, nod, and react naturally—just as a real person would during conversation—making digital interactions feel truly face-to-face.
