What is Phenaki?

Phenaki is an innovative model designed to generate videos directly from textual prompts. It stands out in the realm of artificial intelligence and video synthesis by allowing users to create videos that can be of variable lengths, ranging from a few seconds to several minutes. This capability is powered by a unique approach that leverages a sequence of prompts that can evolve over time, enabling the generation of dynamic and engaging video content.

The model is particularly adept at overcoming the challenges associated with video generation, such as high computational costs, the scarcity of quality text-video data, and the need for flexibility in video length. By employing advanced techniques in video representation and tokenization, Phenaki sets a new benchmark in the field of video synthesis.
