Introducing ByteDance Lynx on WaveSpeedAI: High-Fidelity Personalized Video Generation

The gap between still images and dynamic video content has never been easier to bridge. We’re excited to announce that ByteDance Lynx is now available on WaveSpeedAI, bringing state-of-the-art personalized video generation directly to your fingertips through our lightning-fast inference API.

Lynx represents a breakthrough in subject-consistent video generation. Whether you’re creating marketing content, digital avatars, or creative animations, this model transforms a single image into a fluid 5-second video clip while maintaining remarkable identity fidelity across every frame.

What is ByteDance Lynx?

Lynx is an advanced image-to-video model developed by ByteDance’s Intelligent Creation team. Built on a Diffusion Transformer (DiT) foundation, it employs a sophisticated dual-adapter architecture that sets it apart from conventional video generation tools.

The secret to Lynx’s impressive consistency lies in its two specialized modules:

• ID-Adapter: Uses a Perceiver Resampler to convert ArcFace-derived facial embeddings into compact identity tokens, ensuring the subject’s face remains recognizable throughout the video
• Ref-Adapter: Integrates dense VAE features through cross-attention, preserving fine-grained details like skin texture, hair, and clothing across all frames

This architecture enables Lynx to avoid common pitfalls in AI video generation such as identity drift, copy-paste artifacts, and unrealistic motion—problems that plague many competing solutions.

Key Features

Subject Consistency That Actually Works

Lynx was evaluated on a comprehensive benchmark of 40 subjects and 20 unbiased prompts, resulting in 800 test cases across diverse identities and scenarios. The results speak for themselves: Lynx achieves state-of-the-art performance in face resemblance while delivering competitive prompt following and strong video quality. Unlike other methods that often exhibit unrealistic actions or poor identity resemblance, Lynx consistently preserves facial identity with high fidelity.

Smooth, Natural Motion

Generate fluid, jitter-free animations that look professionally produced. The model handles complex movements naturally, from subtle facial expressions to full-body motion, without the stuttering or warping artifacts common in lesser models.

Flexible Aspect Ratios

Create content for any platform with support for:

• 16:9 — Perfect for YouTube, presentations, and widescreen displays
• 9:16 — Optimized for TikTok, Instagram Reels, and mobile-first content
• 1:1 — Ideal for social media feeds and profile content

Powerful Prompt Control

Guide your video’s motion, style, and atmosphere with descriptive text prompts. Whether you want “walking forward in a forest with cinematic lighting” or “turning to face the camera with a warm smile,” Lynx translates your creative vision into reality.

Incredibly Affordable

At just $0.50 per generation, Lynx delivers professional-quality personalized video at a fraction of traditional production costs. Each run produces a 5-second clip—long enough for impactful social content, short enough for rapid iteration.

Real-World Use Cases

Marketing and Brand Content

Create personalized promotional videos featuring brand ambassadors or client representatives across various scenarios without expensive photo shoots. Generate multiple variations showcasing your product in different settings—all while maintaining perfect visual consistency.

Digital Avatars and Virtual Presenters

Build consistent digital characters for interactive applications, customer service, or educational content. Lynx’s identity preservation makes it ideal for creating virtual presenters who maintain their appearance across unlimited video segments.

Social Media at Scale

Produce engaging short-form content for TikTok, Reels, and Stories. With Lynx’s 9:16 aspect ratio support and subject consistency, you can create a library of on-brand video content featuring consistent characters without repetitive filming sessions.

Training and Educational Content

Develop training videos and tutorials with consistent character representation. The model’s ability to maintain identity across different scenarios makes it perfect for multi-part educational series where instructor presence matters.

Creative Storytelling

Animate illustrations, bring portraits to life, or create character-driven narratives. Artists and content creators can transform static artwork into dynamic video sequences while preserving their unique artistic style.

Multilingual Content Creation

Generate base video content that can be adapted for global audiences. Create consistent character performances that can be localized across different markets, reducing the need for separate production teams for each language.

Getting Started with Lynx on WaveSpeedAI

Getting started is straightforward:

1. Prepare your source image — Use a high-resolution, clear image (JPG or PNG) for optimal subject consistency
2. Write your prompt — Describe the motion, scene, or style you want to achieve. Be specific for best results
3. Select your aspect ratio — Choose 16:9, 9:16, or 1:1 based on your target platform
4. Submit and download — Receive your 5-second video in seconds, not minutes

Pro Tips for Best Results

• Use high-quality source images: Clear, well-lit photos with visible facial features yield the strongest identity preservation
• Be specific in your prompts: Instead of “person walking,” try “walking forward through a sun-dappled forest with cinematic lighting and a gentle breeze”
• Match aspect ratio to platform: 9:16 for vertical social content, 16:9 for horizontal presentations
• Iterate quickly: At $0.50 per generation, you can experiment freely to find the perfect output
