Pixal3D for mlx-serve (8-bit)

TencentARC/Pixal3D repackaged for mlx-serve on Apple Silicon. Tencent's image-to-3D model, built on the TRELLIS.2 backbone with pixel-aligned conditioning: an image with a transparent background becomes a textured PBR GLB. Single-view and multi-view (*_mv) models.

The flow-model (DiT) block projections are affine-quantized to 8 bit, group size 64; everything else is as released.
Includes the DINOv3 image encoder it conditions on (float16); its licence is in dinov3/LICENSE.md.
No background remover is included: send an image with a transparent background (alpha is the subject).

Licences

The Pixal3D weights are MIT (LICENSE). The bundled DINOv3 encoder is Meta's, under the DINOv3 License (dinov3/LICENSE.md), which travels with any redistribution of it. The NAF feature upsampler in naf/ is Apache-2.0 (naf/LICENSE).

Run: mlx-serve --model-dir <folder holding this repo>, then POST /v1/3d/generations. Converted by tests/convert_trellis2_pixal3d.py in the mlx-serve repository.
