Summary - F.748.63 (12/2025) - Framework and general technical requirements of foundation model enhanced digital human systems

Recommendation ITU-T F.748.63 specifies a framework and general technical requirements for foundation model enhanced digital human systems. It introduces a framework that integrates foundation model capabilities into digital human systems, covering modelling, rendering, driving and interaction processes. The Recommendation describes typical application scenarios of foundation models across different phases of digital human systems and specifies technical requirements for the modelling, driving and interaction phases to ensure enhanced intelligence, safety and reliability.
