InstantCharacter is a cutting-edge model designed for open-domain character personalization. It addresses the common limitations of traditional models in terms of generalization ability and image quality. By leveraging a scalable Diffusion Transformer architecture, combined with adaptable adapter modules and a massive character dataset, InstantCharacter delivers high-quality, highly customizable character imagery across diverse scenarios.

Key Features

• Open-Domain Personalization：InstantCharacter excels in generating a wide variety of character appearances, poses, and styles, maintaining high fidelity while allowing extensive personalization — perfect for a wide range of creative and professional applications.
• Scalable Adapter Modules：The model integrates stacked Transformer encoders as adapters that specialize in handling open-domain character features. These adapters interact seamlessly with the latent space of the modern Diffusion Transformer, significantly enhancing the diversity and consistency of generated results.
• Large-Scale Character Dataset Training：To empower InstantCharacter’s capabilities, Tencent AI Lab built a massive character dataset containing tens of millions of samples, covering multi-view character images and paired text-image examples. This robust dataset enables superior identity consistency and strong text-based editability.
