Low-poly generation is becoming one of the most requested features in AI 3D tools. Whether you need game-ready assets, optimized meshes for real-time rendering, or clean retopology for animation — having AI handle the heavy lifting saves hours of manual work.
Right now, based on our Low Poly Arena testing, there are three serious contenders: Hunyuan 3D, Tripo AI, and Rodin Gen-2. Each takes a different approach, with different trade-offs in quality, control, and pricing.
I tested all of them extensively, built a side-by-side comparison viewer with 7 test models, and here's the full breakdown.

Open DemoHunyuan 3D
Hunyuan 3D offers two ways to generate low-poly models: through the main website (Laboratory) and through Hunyuan 3D Studio. The Studio path gives you more control.
Laboratory (Main Site)
In the Laboratory, you can generate low-poly directly from an image or from an existing 3D model. However, the settings are very limited — you can only choose between tris and quads. Everything else (density, polycount) is decided by the model automatically.
Studio (Recommended)
The Studio approach is better. You can't go directly from an image to low-poly here — you first need to generate or upload a high-poly model. But once you have it, the low-poly settings are more granular: you get quads or tris plus a Low / Medium / High density selector.
My recommendation: Use Hunyuan Studio for low-poly. The extra density control makes a real difference in output quality.
Rodin Gen-2
With Rodin, the workflow is two-step. First, you need to generate a model or upload your own. Then you process it to get a mesh.
After the mesh is processed, you can generate a low-poly version with quads or tris and Low or High density.
Note: Rodin produces solid results, but it's the most expensive option by far. See the pricing section below.
Tripo AI
Tripo offers two distinct methods for low-poly generation. The main Tripo model also has a polycount parameter, but if we're talking specifically about what they brand as “low-poly”, there are two paths.
Retopology (Smart Mesh v2)
Upload your own model or use a generated high-poly one, then run retopology. You get quads or tris, polycount control from 0 to 20,000, and an Auto button that lets the model decide the optimal count. I recommend using Auto in most cases.
Tripo is the only tool that gives you explicit polycount control — this can be extremely useful when targeting specific LOD budgets.
Smart Mesh (P1.0)
Smart Mesh (P1.0) is the more interesting option. It generates low-poly directly from an image in about 5 seconds — no 3D model input needed. However, right now it only supports tris and you have to set the polycount manually (0–20,000 range, no Auto mode here).
My take: Smart Mesh (P1.0) is the most promising low-poly model right now. Direct image-to-low-poly in 5 seconds is a game-changer, even with the current limitations.
Pricing Comparison
Here's roughly what each low-poly generation costs. Prices are approximate and may vary depending on your plan.
| Tool / Method | Cost per Model | Notes |
|---|---|---|
| Tripo Smart Mesh (P1.0) | ~$0.25 | Cheapest. Image → low-poly directly |
| Tripo Retopology | ~$0.35 | From existing 3D model |
| Hunyuan 3D (API) | ~$0.75 | Studio gives daily free credits |
| Rodin Gen-2 | ~$2.00 | Most expensive option |
Free option: Hunyuan 3D Studio gives daily credits, so you can do low-poly at no cost if volume is low. Tripo also has a free tier with limited credits.
Feature Comparison
| Feature | Hunyuan 3D | Rodin Gen-2 | Tripo Retopo | Smart Mesh (P1.0) |
|---|---|---|---|---|
| Image → Low Poly | Lab only | No | No | Yes |
| Model → Low Poly | Yes | Yes | Yes | No |
| Quads | Yes | Yes | Yes | Tris only |
| Polycount Control | L/M/H presets | L/H presets | 0–20K + Auto | 0–20K manual |
| Price per Model | ~$0.75 | ~$2.00 | ~$0.35 | ~$0.25 |
Try It Yourself: Interactive Comparison
I ran all three tools through 7 different test models and built an interactive viewer where you can compare the results side-by-side. All cameras are synchronized — rotate one viewport and all six move together. You can toggle individual tools on/off and inspect wireframes and vertex counts.
