MiMo-V2.6 Pro MOPD GGUF for DwarfStar

GGUF files for the MiMo-V2.6 Pro MOPD port in DwarfStar (DS4),

branch kernelpool/ds4:mimo-v26

(pull request: TODO link). Metal only. The model runs over tensor parallelism

between two 512 GB Macs.

MOPD is Xiaomi's update of the MiMo-V2.6 Pro RL checkpoint that reduces

repeated tool calls in agent sessions

(Xiaomi's write-up).

The main model and the DFlash drafter changed; the MTP blocks carry the same

weights as the RL release. The files below replace

kernelpool/MiMo-V2.6-Pro-RL-MXFP4-GGUF

and use the same layout.

Files

The main GGUF is above the Hugging Face single-file limit, so it is stored in

two parts and joined after download, the same way the official DwarfStar Q4

release is.

The main file uses the mimo2 layout: the checkpoint's own MXFP4 experts

repacked without requantization, Q8_0 attention, dense and output weights,

BF16 embeddings, and the three MTP blocks. The DFlash sidecar uses the

dflash layout plus the mask embedding and value scale DS4 needs.

hf download kernelpool/MiMo-V2.6-Pro-MOPD-MXFP4-GGUF --local-dir gguf
cd gguf

Appending the second part to the first keeps the extra disk space to the size

of the second part.

Run

Both Macs need the joined file locally. Each rank keeps half of the attention

heads, half of the routed experts and half of the vocabulary head, about

270 GiB resident, so each Mac needs 512 GB. The link setup is in

docs/DISTRIBUTED.md.

Start the worker first:

git clone -b mimo-v26 https://github.com/kernelpool/ds4 && cd ds4 && make
# Machine B (worker)
./ds4 -m gguf/MiMo-V2.6-Pro-MOPD-MXFP4.gguf --ctx 8192 --mtp \
  --tensor-parallel --role worker --coordinator 192.168.0.1 9911 --transport rdma
# Machine A (coordinator)
./ds4-server -m gguf/MiMo-V2.6-Pro-MOPD-MXFP4.gguf --ctx 8192 --mtp \
  --tensor-parallel --role coordinator --listen 192.168.0.1 9911 --transport rdma

--mtp drafts with the MTP blocks inside the main file; both ranks run the

draft and verify it together, so pass it to both or to neither. Greedy output

follows plain decoding.

The server exposes mimo-v2.6-pro, mimo-v2.6-pro-chat (thinking off) and

mimo-v2.6-pro-reasoner (thinking on).

DS4 does not run the DFlash sidecar or vision under tensor parallelism yet,

so the sidecar is not used for now and no vision encoder is included.

See docs/MIMO_V26.md.

Conversion

Written by gguf-tools/mimo26_quantize.py from XiaomiMiMo/MiMo-V2.6-Pro-MOPD

at revision adea8e2c5373181e5a973fa1ecb343cb31af214b. The converter

de-interleaves the tensor-parallel chunks of the fused QKV projection and

keeps the released MXFP4 expert blocks bit for bit; the source revision is

recorded in the GGUF metadata.

The original checkpoint is released by Xiaomi under the MIT license, which

applies to these files as well.
