Hunyuan 3d V3.1 Text To 3d Rapid API Documentation

Playground

Hunyuan 3D V3.1 Rapid is a fast text-to-3D generation model that quickly creates 3D models from text descriptions. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Hunyuan 3D V3.1 Rapid is Tencent’s fast text-to-3D generation model that creates high-quality 3D models from text descriptions. Simply describe any object — the model generates a complete 3D mesh with textures in seconds. Perfect for rapid prototyping, game assets, e-commerce visualization, and 3D content creation.

Why Choose This?

• Text-driven generation Create complete 3D models from natural language descriptions — no images or 3D expertise required.

• Rapid generation Fast processing delivers 3D assets quickly for rapid iteration and prototyping.

• High-quality output Produces detailed 3D meshes with accurate geometry and textures.

• Prompt Enhancer Built-in tool to automatically improve your descriptions for better 3D results.

• Ultra-affordable Just $0.0225 per generation — cost-effective for high-volume workflows.

Parameters

How to Use

1. Write your prompt — describe the object you want to create (shape, style, details, pose).
2. Use Prompt Enhancer (optional) — refine your description for better results.
3. Run — submit and download your 3D model.

Pricing

Billing Rules

• Flat rate: $0.0225 per generation
• No additional charges for mesh complexity or texture quality

Best Use Cases

• Game Development — Quickly generate 3D assets from concept descriptions.
• Prototyping — Rapidly visualize object ideas in 3D before production.
• E-commerce — Create 3D product models for interactive experiences.
• AR/VR Content — Generate 3D assets for augmented and virtual reality applications.
• 3D Printing — Generate printable 3D models from text descriptions.
• Creative Exploration — Experiment with 3D concepts without modeling skills.

Pro Tips

• Be specific about shape, style, pose, and details in your prompt.
• Include style keywords like “cartoon style”, “realistic”, “low poly”, or “high detail”.
• Describe the pose or orientation for character models (e.g., “standing pose”, “T-pose”).
• Use the Prompt Enhancer to automatically refine vague descriptions.
• Start with simple objects and iterate to more complex designs.

Notes

• Prompt is the only required field.
• Output format is a 3D mesh with textures.
• More detailed prompts generally produce better results.
