Parameters
1,500,000,000Source for Parameters (opens in a new tab)

DiT size from Table 1; excludes the separate 82M geometry VAE and material model.

Architecture
24-layer latent diffusion transformer, width 2048, 16 attention heads; feed-forward expansion 4×. Geometry uses a separate multiresolution VAE.Source for Architecture (opens in a new tab)

Input modalities
TextSource for Input modalities (opens in a new tab)

Text-to-shape evaluation model. Adapter support is not inherited from XL-P.

Output modalities

Training sequence length
1024 geometric latent positions in Table 3 evaluation; 64 channels per position.Source for Training sequence length (opens in a new tab)

Geometric representation, not prompt-token capacity.

Published training data
527,000 filtered ShapeNet/Objaverse objects; remeshed and annotated through the paper’s processing pipeline.Source for Published training data (opens in a new tab)
Geometry resolution
Paper inference: 100 denoising steps, occupancy sampled on a 512³ grid, then Marching Cubes.Source for Geometry resolution (opens in a new tab)

Reported research configuration; not a hosted service limit.

PBR materials
Not supportedSource for PBR materials (opens in a new tab)

This record is the geometry DiT. CLAY Material Diffusion supplies PBR textures separately.

Training hardware

Data & enterprise terms

Research access is not assigned the commercial Rodin API retention policy.

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

Qualified unreleased-weight classification as reviewed: the official OpenCLAY tree contains only README and example images; the linked organization model listing is empty. The paper documents trained models. This does not assert a permanent proprietary license or rule out future releases; public research publication and integration code are not weight releases.
