Hunyuan

Hunyuan is Tencent's family of open-source generative models spanning text-to-image, text-to-video, and 3D asset generation.

Model Variants

Hunyuan-DiT

• Text-to-image diffusion transformer with native Chinese and English support
• 1.5B parameter DiT architecture, native 1024x1024 resolution
• Bilingual text encoder for strong CJK text rendering in images
• v1.2 is the latest version with improved quality

HunyuanVideo

• Large-scale text-to-video and image-to-video generation model
• 13B+ parameters, the largest open-source video generation model
• Dual-stream to single-stream transformer architecture with full attention
• MLLM text encoder (decoder-only LLM) for better instruction following
• Causal 3D VAE with 4x temporal, 8x spatial, 16x channel compression
• Generates 720p video (1280x720) at up to 129 frames (~5s at 24fps)
• FP8 quantized weights available to reduce memory by ~10GB
• Outperforms Runway Gen-3, Luma 1.6 in professional evaluations
• 3 workflow templates available

Hunyuan3D 2.0

• Image-to-3D and text-to-3D asset generation system
• Two-stage pipeline: Hunyuan3D-DiT (shape) + Hunyuan3D-Paint (texture)
• Flow-based diffusion transformer for geometry generation
• High-resolution texture synthesis with geometric and diffusion priors
• Outputs textured meshes in GLB/OBJ format
• Outperforms both open and closed-source 3D generation models
• 7 workflow templates available

Key Features

• Native bilingual support (Chinese and English) across the family
• Strong text rendering in generated images (Hunyuan-DiT)
• State-of-the-art video generation quality (HunyuanVideo)
• End-to-end 3D asset creation with texturing (Hunyuan3D)
• Multi-resolution generation across all model types
• Prompt rewrite system for improved generation quality (HunyuanVideo)

Hardware Requirements

• Hunyuan-DiT: 11GB VRAM minimum (fp16), 16GB recommended
• HunyuanVideo 540p (544x960): 45GB VRAM minimum
• HunyuanVideo 720p (720x1280): 60GB VRAM minimum, 80GB recommended
• HunyuanVideo FP8: Saves ~10GB compared to fp16 weights
• Hunyuan3D 2.0: 16-24GB VRAM for shape + texture pipeline

Common Use Cases

• Bilingual content creation and marketing materials
• Asian-style artwork and illustrations
• Text-in-image generation (Chinese/English)
• High-quality video generation from text or image prompts
• 3D asset creation for games, design, and prototyping
• Textured mesh generation from reference images

Key Parameters

• steps: 25-50 for Hunyuan-DiT (default 40), 50 for HunyuanVideo
• cfg_scale: 5-8 for DiT (6 typical), 6.0 embedded for HunyuanVideo
• flow_shift: 7.0 for HunyuanVideo flow matching scheduler
• video_length: 129 frames for HunyuanVideo (~5s at 24fps)
• resolution: 1024x1024 for DiT, 720x1280 or 544x960 for video
• negative_prompt: Recommended for Hunyuan-DiT quality control
