Introducing HunyuanImage 2.1: Tencent’s Powerful 2K Text-to-Image Model Now on WaveSpeedAI

The AI image generation landscape just got a major upgrade. We’re excited to announce that HunyuanImage 2.1, Tencent’s groundbreaking 17-billion parameter text-to-image model, is now available on WaveSpeedAI. This model has quickly risen to the top of the Artificial Analysis Image Arena rankings, outperforming other leading open-weight models like HiDream-I1-Dev and Qwen-Image—and now you can access it through our lightning-fast inference API.

What is HunyuanImage 2.1?

HunyuanImage 2.1 is an advanced Diffusion Transformer (DiT) model developed by Tencent’s Hunyuan team, purpose-built for generating stunning high-resolution images at native 2K resolution (2048×2048 pixels). Unlike many models that upscale lower-resolution outputs, HunyuanImage 2.1 generates true 2K images from the ground up, resulting in exceptional clarity, rich details, and photorealistic quality.

What sets this model apart is its raw, un-distilled architecture. While distilled models sacrifice quality for speed, HunyuanImage 2.1 preserves the full fidelity of the diffusion process, delivering images with superior texture, lighting, and composition. The result? Professional-grade visuals that rival closed-source commercial solutions.

Key Features

• Native 2K Resolution: Generate images at 2048×2048 and other 2K-class resolutions without upscaling artifacts. The model supports multiple aspect ratios including 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, and 2:3—perfect for social media, print, and advertising.

• 17 Billion Parameters: The massive parameter count enables exceptional semantic understanding and visual fidelity, handling complex prompts with multiple subjects, intricate scenes, and nuanced artistic directions.

• Photorealistic Quality: Community testing confirms industry-leading accuracy in human anatomy, particularly hand details and facial expressions—areas where many AI models struggle. Complex environments render with proper perspective, lighting, and atmospheric effects.

• Superior Text Rendering: With its glyph-aware ByT5 encoder, HunyuanImage 2.1 achieves over 95% accuracy in generating readable text within images—far exceeding other open-source alternatives. Perfect for neon signs, posters, and branded content.

• Bilingual Support: Native support for both English and Chinese prompts makes this model exceptionally versatile for global creative teams.

• Built-in Prompt Enhancement: The integrated PromptEnhancer module automatically enriches your text prompts with additional details and descriptive content, significantly improving output quality even from simple inputs.

• Refiner Technology: An included refiner stage optimizes final image quality, reducing artifacts and enhancing fine details for publication-ready results.

• Efficient 32× VAE Compression: The highly expressive VAE with 32×32 spatial compression generates 2K images with the computational efficiency of 1K generation, delivering faster results without sacrificing quality.
