MIBURI release checkpoints

Companion model weights for MIBURI: Towards Expressive Interactive Gesture Synthesis (CVPR 2026).

• Paper: https://arxiv.org/abs/2603.03282
• Project page: https://vcai.mpi-inf.mpg.de/projects/MIBURI/
• Code: https://github.com/m-hamza-mughal/miburi

These weights are not used standalone — they are loaded by the MIBURI demo server from the code repository. The intended way to fetch them is:

git clone https://github.com/m-hamza-mughal/miburi
cd miburi
pip install .
miburi-download-assets           # https://huggingface.co/m-hamza-mughal/miburi-release-assets
miburi-download-checkpoints      # this repo, pulled into experiments/
miburi-demo

Contents

8 directories under experiments/, two release tracks × {3 codecs + 1 Gesture LM}:

Dir	Role
demoexp_release_uppercodec/	Upper body + hands codec
demoexp_release_lowercodec/	Lower body + trans-velocity codec
demoexp_release_facecodec/	Face / expression codec
demoexp_release_gtdm3_goodspk/	GTDM3 LM, BEATX 4-speaker subset
allspk_release_uppercodec/	Upper codec, all-speaker
allspk_release_lowertranscodec/	Lower codec, all-speaker
allspk_release_facecodec/	Face codec, all-speaker
allspk_release_gtdm3_exp/	GTDM3 LM, all 23 BEATX speakers

Each codec dir holds config.yaml + a single last_<NNN>.safetensors. The GTDM3 dirs additionally hold speaker_id_to_index.json and tokens_idle_slices/{idle_upper,idle_face}_tokens_slices.npz that the demo server reads at startup.
