Introducing HunyuanVideo-1.5 Text-to-Video on WaveSpeedAI

The race to democratize AI video generation just took a major leap forward. WaveSpeedAI is excited to announce the availability of HunyuanVideo-1.5 Text-to-Video—Tencent’s groundbreaking lightweight video generation model that brings professional-quality video creation to everyone, without the need for expensive hardware or complex setups.

What is HunyuanVideo-1.5?

HunyuanVideo-1.5 represents a significant milestone in open-source video generation technology. Released by Tencent in November 2025, this 8.3-billion parameter model delivers state-of-the-art visual quality and motion coherence while being remarkably efficient. Unlike its larger predecessors and competitors, HunyuanVideo-1.5 was specifically engineered to run on consumer-grade GPUs—a design philosophy that makes high-quality video generation accessible to independent creators, small studios, and developers alike.

The model builds upon Tencent’s proven Hunyuan architecture, combining an innovative Diffusion Transformer (DiT) with a 3D Causal VAE (Variational Autoencoder). This design achieves impressive 16× spatial compression while maintaining exceptional visual quality, enabling fast inference without sacrificing output fidelity.

Key Features

HunyuanVideo-1.5 stands out in the crowded text-to-video landscape for several compelling reasons:

• Lightweight Yet Powerful: With only 8.3B parameters, HunyuanVideo-1.5 achieves visual quality comparable to much larger models. In benchmarks, it outperforms Wan2.2 and Kling2.1 in instruction following, structural stability, and motion clarity.

• Superior Motion Coherence: The model excels at maintaining consistent subject identity and smooth motion throughout generated clips, a common weakness in many video generation systems.

• Flexible Duration Options: Generate videos at 5, 8, or 10-second lengths, giving you control over clip duration based on your project needs.

• Strong Text Alignment: The model utilizes a pre-trained Multimodal Large Language Model as its text encoder, resulting in exceptional text-to-video alignment. Internal benchmarks show an instruction following accuracy of 8.4/10.

• Multiple Resolution Support: Choose between 480p and 720p output resolutions, with seamless upscaling options available for higher-quality final delivery.

• Selective and Sliding Tile Attention (SSTA): This innovative mechanism reduces computational overhead for longer sequences, achieving 1.87× speedup for 10-second 720p synthesis compared to standard attention mechanisms.

Real-World Use Cases

HunyuanVideo-1.5’s versatility makes it suitable for a wide range of creative and professional applications:

Social Media Content Creation

Generate eye-catching video content for TikTok, Instagram Reels, or YouTube Shorts directly from text descriptions. Describe your scene, add stylistic direction, and produce scroll-stopping content in seconds rather than hours.

Marketing and Advertising

Create product visualization videos, promotional clips, and brand storytelling content without expensive production crews. Perfect for A/B testing different creative concepts before committing to full production.

Storyboarding and Pre-visualization

Film directors and animators can quickly generate rough visualization of scenes from script descriptions, accelerating the pre-production process and improving communication with stakeholders.

Educational Content

Educators and course creators can produce illustrative video segments to explain complex concepts, making learning materials more engaging and accessible.

Game Development and Concept Art

Game studios can generate animated concept pieces and environmental videos to explore visual directions before committing development resources.

Rapid Prototyping for Creative Projects

Test creative ideas quickly without the overhead of traditional video production. Iterate on concepts in minutes rather than days.

Getting Started on WaveSpeedAI

Using HunyuanVideo-1.5 on WaveSpeedAI is straightforward and requires no technical setup:

1. Navigate to the Model: Visit HunyuanVideo-1.5 Text-to-Video on WaveSpeedAI.

2. Craft Your Prompt: Write a detailed text description of your desired video. Be specific about characters, actions, environments, camera movements, and visual style. For example: “A golden retriever running through a sunlit meadow, chasing butterflies, cinematic slow motion, warm afternoon lighting, shallow depth of field.”

3. Configure Settings: Select your preferred duration (5s, 8s, or 10s) and resolution (480p or 720p). Adjust inference steps if you want to balance speed versus quality.

4. Generate: Click generate and watch as your vision comes to life. With WaveSpeedAI’s optimized infrastructure, you’ll receive your video with no cold starts and minimal wait times.

5. Enhance (Optional): Use WaveSpeedAI’s video upscaling tools to enhance your output to even higher resolutions for professional delivery.

Tips for Best Results

• Be Descriptive: Include details about who is in the scene, what they’re doing, where the action takes place, and how the camera moves.
• Specify Style: Mention artistic direction like “cinematic lighting,” “anime style,” “documentary handheld,” or “neon cyberpunk aesthetic.”
• Start Short: 5-8 second clips typically produce the most coherent results. Build longer sequences by combining multiple generations.
• Use Consistent Seeds: When creating a series of related shots, reuse similar prompts and seeds to maintain stylistic consistency.

Why Choose WaveSpeedAI?

Running HunyuanVideo-1.5 on your own hardware requires at least 14GB of GPU memory with model offloading, and optimal performance needs even more. WaveSpeedAI eliminates these barriers entirely:

• No Cold Starts: Your generations begin immediately—no waiting for models to load.
• No Hardware Requirements: Access powerful inference without investing in expensive GPUs.
• Affordable Pricing: Pay only for what you use at $0.02/second for 480p and $0.04/second for 720p.
• Ready-to-Use REST API: Integrate video generation directly into your applications and workflows.
• Optimized Performance: Our infrastructure is tuned for the fastest possible inference times.

Conclusion

HunyuanVideo-1.5 represents a significant step forward in making high-quality AI video generation accessible to everyone. Its combination of lightweight architecture, strong visual quality, and excellent motion coherence makes it an ideal choice for creators who need reliable, fast, and affordable video generation.

Whether you’re a content creator looking to streamline your workflow, a developer building the next generation of creative tools, or a business seeking to scale video production without scaling costs, HunyuanVideo-1.5 on WaveSpeedAI provides the performance you need.
