# TRELLIS.2-4B — GGUF (f16)

GGUF (`f16`) conversions of [microsoft/TRELLIS.2-4B](https://huggingface.co/microsoft/TRELLIS.2-4B)
for the **[trellis2cpp](https://github.com/localai-org/trellis2cpp)** /
[ggml](https://github.com/ggml-org/ggml) runtime — a CUDA-free, PyTorch-free C++ port of
the TRELLIS.2 image-to-3D pipeline. Load these directly; no safetensors conversion or
Python is needed at inference.

The image conditioning encoder (DINOv3) and the sparse-structure decoder are published
separately:
[dinov3-vitl16-pretrain-lvd1689m-GGUF](https://huggingface.co/LocalAI-io/dinov3-vitl16-pretrain-lvd1689m-GGUF)
and
[TRELLIS-image-large-GGUF](https://huggingface.co/LocalAI-io/TRELLIS-image-large-GGUF).

## Conversion

Converted from the upstream `bf16`/`fp16` safetensors to GGUF `f16` (ggml ftype 1) with
the `convert_*_to_gguf.py` scripts in the trellis2cpp project. No weights were retrained
or modified — this is a format conversion only.
