Generative AI presents a duality: the foundation models that empower creators with audio-visual generation can also expose them to unauthorized imitation and style appropriation. This EXPO Workshop examines how AI can both protect creators and expand their creativity. The first half features talks on core foundation model algorithms, protective AI, and audio-visual generation for creators. The second half invites participants to experience live demos and discuss directly with speakers. Encouraging debate on open problems and competing approaches, the workshop connects research, industry, and creative communities around responsible, empowering AI.
