short_description: The largest proprietary library of human-authored 3D assets

# A23D — The largest proprietary library of human-authored 3D assets — built for AI training and generative 3D
A23D is a proprietary dataset of **500,000+ 3D models, PBR textures, decals, and IES profiles**, entirely human-authored in-house. Every asset is built by our own team to one concept, one vision, one structure — delivering consistency across scale, orientation, topology, materials, and metadata that open-source and marketplace datasets can't match.
## What Makes It Different
Every model is textured with our own PBR materials, giving us **component-level geometry-and-material ground truth** (albedo, roughness, metallic, normals). Every asset in the corpus contains linked geometry, materials, topology, taxonomy, dimensions, and component-level metadata created under a single production standard.
This forms a **structured graph connecting geometry, materials, semantics, topology, dimensions, and categories** — a depth of per-asset metadata not found in open-source or marketplace datasets.
## Dataset at a Glance
- 400,000+ 3D Models
- 100,000+ PBR Textures
- 14,000+ Decals
- 10,000+ IES Profiles
## Use Cases
- Training data for generative 3D and 3D foundation models
- Geometry-and-material ground truth for reconstruction and material estimation
- Structured 3D corpora for research in topology, semantics, and taxonomy
## Licensing
We license this dataset for **AI training and generative 3D**. To discuss access, reach out via [enterprise@a23d.co](https://a23d.co/) or visit a23d.co/ai |
