Hunyuan Image 3.0

bytencent

Hunyuan Image 3.0 is Tencent’s flagship AI image-generation model and one of the largest open-source text-to-image systems available. It uses an advanced mixture-of-experts (MoE) architecture with an 80 billion-parameter backbone to produce high-fidelity visuals with strong prompt understanding, world knowledge reasoning, and accurate multilingual text rendering. The model supports ultra-long prompts (1000+ characters) and generates detailed, context-aware images across diverse styles — from photorealistic scenes to illustrations — making it a powerful open alternative to top commercial image models. Hunyuan Image 3.0 was released and open-sourced on September 28, 2025.
