With the v0.5 model, we introduce two upgrades to the auto-regressive base model for 3D geometry generation from text: *higher fidelity 3D compositions* and *bounding box conditioning*.
The example gif below shows the model's capacity to generate 3D shapes capturing mixtures of concepts expressed in text, for example *mechanical lobster with mechanical tank treads*. The v0.5 model also shows significantly better text adherence, for example the *lowpoly paper craft victorian rabbit*.

</p>

With bounding box conditioning, we observe novel 3D generations where the model balances between the two conditioning inputs -- text prompt and global aspect ratio. In the gif below, notice how the model creatively interprets the *seashell* or *tall pagoda* prompts into distinct 3D shapes. The model sometimes struggles when the bounding box is too extreme for a given prompt, for example the *cat*, where it can produce disconnected components or generates it along a diagonal to fit the bounding box constraints.

</p>

For a technical overview of the methods behind these two improvements, please refer to our latest <a href=https://arxiv.org/abs/2503.15475 target="_blank">v3 report on arXiv</a>. The latest model was trained on an additional ~2.8 million synthetic 3D assets. We introduced several refinements to VQ-VAE architecture and training procedures, and increased the VQ-VAE latent length from 512 to 1024 to increase generation fidelity.
