ChatAnything aims to infuse LLM-based virtual characters with personality, appearance, and voice, enabling engaging online video chats. Users can simply provide a text description to create virtual characters with distinct looks, personalities, and ways of speaking. ChatAnything leverages the contextual learning capabilities of LLMs for personality generation, and introduces two innovative concepts: MoV (Voice Mixing) and MoD (Appearance Mixing) technologies for diverse voice and appearance generation. Its key features include virtual character portrait generation, personality generation, voice generation, and facial animation generation. Use cases include producing video chatbots and interactive virtual characters.
