+# MiMo-V2.6-Flash-RL GGUF — calibration reference
+
+This repository holds intermediate artifacts actually generated while building [MiMo-V2.6-Flash-RL Mixed-Quant GGUF](https://huggingface.co/Baekpica/MiMo-V2.6-Flash-RL-Mixed-Quant-GGUF). The final compact mixed variant belongs in that separate repository.
+
+The source is [XiaomiMiMo/MiMo-V2.6-Flash-RL](https://huggingface.co/XiaomiMiMo/MiMo-V2.6-Flash-RL), pinned to [`3b38d063180c3e4aed9691fdc735f3d10b266ee4`](https://huggingface.co/XiaomiMiMo/MiMo-V2.6-Flash-RL/tree/3b38d063180c3e4aed9691fdc735f3d10b266ee4).
+
+## Reference representation
+
+The four `MXFP4-BF16` shards preserve the original routed experts through an exact MXFP4 repack and expand source FP8 dense matrices to BF16. Control tensors are stored as F32. **This is not a full-BF16 source checkpoint or a Q8_0 baseline.** It provides original-checkpoint values for importance-matrix collection without recalibrating from the final IQ2 weights.
+
+| Shard | Bytes |
+|---|---:|
+| `MiMo-V2.6-Flash-RL-MXFP4-BF16-00001-of-00004.gguf` | 44,499,128,352 |
+| `MiMo-V2.6-Flash-RL-MXFP4-BF16-00002-of-00004.gguf` | 44,493,179,840 |
+| `MiMo-V2.6-Flash-RL-MXFP4-BF16-00003-of-00004.gguf` | 44,493,179,840 |
+| `MiMo-V2.6-Flash-RL-MXFP4-BF16-00004-of-00004.gguf` | 41,422,766,592 |
+| **Total** | **174,908,254,624** |
+
+Keep all shards together and open the first shard. The language artifact includes the checkpoint's three embedded MTP blocks; this is not evidence of validated speculative decoding. Multimodal encoders and the separate DFlash model are separate components and are not supplied by these four shards alone.
+
+## Validation status
+
+- All 90 downloaded source repository files passed Hub checksum verification.
+- Independent MXFP4 repacking and tensor-parallel QKV ordering checks passed.
+- All 36,096 expert matrices were covered by a deterministic **sampled-row** audit: 108,257 rows matched the independently repacked source. See `reference-audit.json`; this is not an exhaustive payload comparison.
+- The reference loaded on a B300 GPU and passed a short arithmetic decode check.
+- Original-representation text imatrix collection is running as of 2026-09-22.
+- Final mixed-model quality, multimodal end-to-end behavior, MTP/DFlash execution, and DGX Spark serving remain pending. No throughput or benchmark qualification is claimed here.
+
+`artifact-manifest.json` records exact file sizes and SHA-256 digests. `SHA256SUMS` can be checked after download:
+
+```bash
+hf download Baekpica/MiMo-V2.6-Flash-RL-GGUF --local-dir ./MiMo-reference
+cd ./MiMo-reference
+sha256sum -c SHA256SUMS
+```
+
+## Chat template and reproduction
+
+`chat_template.jinja` is copied byte for byte from the pinned source. Use the original MiMo tokenizer and special-token mapping. Correct image, audio, and video processing additionally requires the corresponding native encoder and input protocol.
+
+The conversion uses a local MXFP4 extension to llama.cpp revision `5836771`. Reproduction scripts will accompany the mixed release and private Spark handoff. The reference's approximately 175 GB file size is not the compact DGX Spark target; see the separate mixed model card for that recipe and its current estimates.
+
+## License
+
+MIT, inherited from the pinned upstream model.
