Introduction
ChatGPT
Generative AI is like a wizard’s cauldron, brewing images, text, and videos from data. Its magic lies in learning from this data to create new, realistic content. Models like DALL-E have amazed us by turning prompts into striking visuals. Video generation was a tough challenge until recently. Now, Mora, a collaborative multi-agent framework, aims to enhance and replicate OpenAI’s Sora capabilities.
Video generation is more complex than creating a single frame; it involves weaving a sequence where each moment flows into the next, creating a dynamic story. Videos must maintain consistency within frames and over time, embodying the dynamics of a moving world. It’s like directing a film where the scriptwriter, director, and entire cast are one AI model.
