Seed3D 2.0

What is Seed3D 2.0?

Seed3D 2.0 is ByteDance Seed's second-generation image-to-3D model. It builds geometry in two passes, overall shape first and fine detail second, to keep sharp edges, thin walls and complex shapes, then one mixture-of-experts model paints the full set of PBR maps. You get a UV-mapped mesh at 100,000, 500,000 or 1,000,000 faces.

It is the current version and the only ByteDance 3D model Volcengine lists. ByteDance sells it only as a hosted API on Volcengine, its China cloud, which asks individual developers for real-name verification.

What changed from Seed3D 1.0?

Sharper shapes and better materials: ByteDance's raters picked 2.0 over 1.0 in almost every shape comparison.

Geometry

Two passes, coarse shape then fine detail, replace 1.0's single pass; raters preferred 2.0's shapes 98.3% of the time.

Materials

One PBR model with mixture-of-experts layers replaces 1.0's chain of texture models; 2.0 won 87.3% of textured comparisons.

Beyond single objects

Part splitting, jointed objects and scene layouts appear in the research, though not yet in the API.

Availability

Volcengine's model list now shows only Seed3D 2.0 for ByteDance's own 3D generation.

Who is Seed3D 2.0 best for?

Seed3D 2.0 is best for game, product and simulation teams that can use ByteDance's China cloud and want one image turned into a UV-mapped mesh with full PBR materials.

• Game and product asset teams

  It returns a textured mesh with albedo, metallic and roughness maps, and ByteDance says text and logos on products stay legible.

• Hard-surface objects

  Its two-pass geometry step is built for sharp edges, thin walls and complex shapes, where earlier image-to-3D models blur.

• Simulation and robotics research

  ByteDance's research shows part splitting, jointed objects exported as URDF for Isaac Sim and whole-scene layouts, though the API offers image-to-3D only.

• Developers already on Volcengine

  It uses the same Ark API key as ByteDance's Doubao models, allows 300 requests a minute and bills only for delivered files.

What's included with Seed3D 2.0?

Three detail levels up to 1 million faces, glb, obj, usd and usdz export, a full PBR material set, and an async API with a browser trial.

Three detail levels

Pick 100,000, 500,000 or 1,000,000 faces per model with one request parameter.

Four export formats

Download results as glb, obj, usd or usdz.

Full PBR materials

Albedo, metallic and roughness maps come from one unified model instead of 1.0's chain of separate ones.

Async task API

Create a job with an image URL, poll its status, then fetch the file; up to 5 jobs run at once.

No-code trial

Volcengine's API Explorer and experience center run the model in the browser before you write code.

Pay only for results

Volcengine bills by the number of 3D files it delivers, so failed jobs cost nothing.

How does Seed3D 2.0 work?

1. Open a Volcengine account

   Register, complete real-name verification and create an Ark API key; new accounts get 2 million free tokens for Seed3D 2.0.

2. Send an image

   Create a 3D task with an image URL and options for face count and file format.

3. Wait and poll

   Check the task ID until it finishes; Volcengine says jobs usually take from a few minutes to more than ten.

4. Download within 24 hours

   The file link and task data are deleted after 24 hours, so save the model as soon as it is ready.

How much does Seed3D 2.0 cost?

Seed3D 2.0 is sold only through Volcengine, ByteDance's cloud in China, at ¥2.40 (Chinese yuan) per 3D model, and Volcengine lists 2 million free tokens for it, enough for about 66 models.

Volcengine gives new accounts a free quota of 2 million tokens for Seed3D 2.0, about 66 models at 30,000 tokens each; once it runs out, calls fail until you complete real-name verification and switch the model on. ByteDance publishes no US dollar price: the model is not on BytePlus, its international cloud, and Volcengine's pricing page is in Chinese with prices in yuan. Full pricing on volcengine.com.

Seed3D 2.0 pros and cons

ByteDance's own raters prefer its textured assets to five commercial rivals, but it is sold only on China's Volcengine, jobs take minutes, and the API does image-to-3D only.

What are the best Seed3D 2.0 alternatives?

Tripo AI for text-to-3D and rigging, Rodin for dollar pricing with pay-per-result credits, and SAM 3D for free weights you run yourself.

Tripo AIFree

Choose it when you also need text-to-3D, auto-rigging and FBX export, from a web app or an English-language API.

RodinFree

Choose it when you want US dollar pricing and to pay only for results you keep; its free plan charges $1.50 a credit per confirmed model, and it takes text prompts as well as images.

SAM 3DFree

Choose it when you want free, royalty-free weights to run on your own GPU, especially for objects and people in cluttered photos; it gives Gaussian splats rather than PBR meshes.
