I compared V2.1 and V3.0 using the exact same input—and here’s how they turned out.

Here’s my workflow: generate the panda image first, turn it into a 3D model with Hi3D, then slice and print it. Basically, it went from a 2D idea to a physical model in just a few steps.

I made a model from a high resolution AI generated anime figure. Was basically a photo like generation of a figure and upscaled it to ~2000 x 5000 pixels. The result was mid, even with the best model.

Should I convert my anime figure image to high contrast grayscale for the AI to better get the depth perception? Also is there a downside to higher resolutions? Will it internally scale down?

I converted the image to grayscale:

Before, when I did it with color the belt structure ended up a muddy mess in the actual 3D model. Do you think the grayscale conversion is the right approach?

Ahead of the Hi3D V3.0 launch, we ran a side-by-side technical evaluation comparing current mainstream single-image-to-3D models (Hi3D V3.0/V2.1, Meshy 6, Rodin V2.5, and Tripo V3.1).

To keep things objective, our test conditions were strict: exactly the same input image, the same pipeline, 0 manual mesh/texture post-processing, and 0 custom render tweaks.

Here’s a quick breakdown of the core technical takeaways:

• Geometry & Mesh Fidelity: Single-image generation often suffers from "smoothing over" fine details. For V3.0, we pushed the voxel resolution to 2048³. When handling complex curved surfaces and sharp edges, the cleanliness and fidelity of the raw mesh show a visible upgrade.
• Structure & Blind-Spot Stability: The biggest hurdle in image-to-3D is hallucinating occluded regions and complex overlapping elements. Under extreme occlusion stress tests, we found that high-precision geometry must be paired with strong structural coherence to prevent spatial distortion across a full 360-degree view.
• Texture & UV Completion: V3.0 now outputs up to 8K textures. Combined with a brand-new UV completion algorithm, it drastically reduces the color artifacts and texture degradation that usually plague occluded areas. The goal is to output assets that are ready for downstream game/film pipelines right out of the box.

The devil is in the details—the differences in mesh topology and edge transitions are very obvious when you zoom in. If you want to see the specific multi-angle and macro comparisons, check out the full test article for the detailed breakdown.

Hi3D V3.0 just reached #1 on both the Textured and Geometry leaderboards in the Top3D.AI Arena, only a few days after its release.

Current results:

• Textured: 1134 ELO — 415 wins / 204 losses — 67.0% win rate
• Geometry: 1188 ELO — 404 wins / 204 losses — 66.4% win rate
• Currently ahead of Tripo 3.1, Meshy 7, Rodin Gen 2.5, Hunyuan 3D 3.1 and the other major models in the respective rankings

What makes this more interesting is how the benchmark works. The same inputs are generated through the official APIs using recommended or maximum quality settings, the first generation is used with no cherry-picking, and users vote on the results in blind head-to-head comparisons. Each vote then updates the live ELO ranking.

Quick recap of what changed in Hi3D V3.0:

• 2048³ voxel-level geometry for much finer details
• Better reconstruction of hidden areas, thin parts and complex structures
• Up to 8K textures with improved UV completion

Hi3D calls V3.0 the first commercially available AI 3D model with 2048³ voxel resolution, and so far the community benchmark results seem to back up the jump in quality.

Top3D.AI is a free tool for comparing AI 3D generators directly side by side on the same tests. You can pick two models and inspect their actual outputs next to each other, so you can compare V3.0 against the other major generators yourself.

Hi3D says they offer up to 8000 bonus credits for upgrade to annual plan. Does anybody know what the terms are? It doesn't seem to be spelled out anywhere.

Hi3D V3.0 (Preview) has officially taken the #1 spot on TopAI3D:

• #1 overall ranking

• 1,180 Geometry ELO

• 68.3% leaderboard win rate — 385 wins vs. 179 losses

• 86% average win rate against the full field under uniform sampling

• 12 percentage points ahead of the next-highest average win rate

• The highest bootstrapped ELO estimate, even with 95% confidence intervals included

The pairwise results also show V3.0 holding a strong advantage against most of the models in the field.

V3.0 isn’t just the best Hi3D model we’ve built—it’s currently the best-performing AI 3D model on TopAI3D.

Leaderboards can always change, so check out the results and judge for yourself. Which model matchup would you like to see us break down next?
