Seed 3D API: 92.8% Win over Tripo 3.0

The Seed 3D API gives developers programmatic access to ByteDance's Seed3D V2.0, a foundation model that turns a single image into a production-ready 3D asset. Each call returns a textured, PBR-shaded mesh delivered as a downloadable .zip archive through Atlas Cloud's OpenAI-compatible platform. Released April 23, 2026, Seed3D V2.0 reached a 92.8% win rate over Tripo 3.0 on geometry quality in blind evaluations by 60 professional 3D modelers.

From a single reference photo you can generate game props, characters, e-commerce AR previews, and architectural concept models without manual modeling. Because every output ships with full PBR material maps, the assets drop straight into Unity, Unreal Engine, and web 3D viewers with realistic surfaces already applied. Studios rely on it to compress asset production from days to minutes while keeping clean topology suitable for real-time rendering.

Sign up, generate one API key, then send a POST request with the model set to bytedance/seed3d-v2.0/image-to-3d and either an image URL or a base64 input. The Seed 3D API is OpenAI-compatible and billed pay-as-you-go, so there is no subscription or minimum commitment to begin. Start building today.

The model accepts a single image in jpg, jpeg, png, webp, or bmp format, up to 4096 by 4096 pixels and 10 MB in size. Aspect ratios between 0.4 and 2.5 are supported, and each image can be passed as either a URL or a base64 data URI. Clear, well-lit subjects on simple backgrounds tend to produce the most accurate geometry.

Every generation returns GLB, OBJ, USD, and USDZ files together in one .zip archive, each carrying the same PBR texture set. You can also select a subdivision level of low, medium, or high, corresponding to roughly 100,000, 500,000, and 1,000,000 polygon faces. GLB suits Unity, Unreal, and web workflows, while USDZ targets Apple AR Quick Look on iOS and iPadOS.

The Seed 3D API uses pay-as-you-go pricing at $0.353 per generation, with no subscription, seat fees, or hidden platform charges. Since billing is per call, you pay only for the assets you actually create, which keeps both quick experiments and large batch runs predictable. One OpenAI-compatible key covers access with no upfront commitment.

In blind evaluations by 60 professional 3D modelers, Seed3D V2.0 reached a 92.8% win rate over Tripo 3.0 on geometry and won more than 69% of texture comparisons against leading benchmarks. Its coarse-to-fine two-stage Diffusion Transformer resolves sharp edges and thin-walled structures that single-stage models often soften. A unified PBR pipeline then produces albedo, normal, metallic, and roughness maps in one pass, keeping material properties physically consistent.

Yes. Its clean topology and engine-ready GLB and OBJ exports fit directly into real-time game and AR pipelines. That said, ByteDance still recommends human review before final deployment, since fine geometry detail and UV mapping edge cases can vary across object categories. Note also that the Atlas Cloud endpoint is image-to-3D, so it builds assets from a single image rather than from text or video prompts.
