MiMo-V2.6-Distill-Qwen-9B-Ablitrated-oQ5e

Speculative Decoding / MTP Note: The vanilla Qwen3.5 MTP head was detached from this refusal-ablated checkpoint. Hikari07jp's refusal ablation shifts residual activation vectors, causing base MTP draft heads to trigger verification divergence and rollback loops under speculative decoding. This model runs cleanly with standard autoregressive generation (and pure text variants are available as Text-oQ4e / Text-oQ3e).

An Apple MLX enhanced oQ5 (oQ5e) quantization of Hikari07jp/MiMo-V2.6-Distill-Qwen-9B-Ablitrated, built with oMLX using 128 calibration samples at sequence length 512, strict importance-matrix coverage, BF16 compute, and group size 64.

The official MiMo checkpoint declares an MTP layer but does not ship MTP weights. This repository grafts the compatible native MTP head from mlx-works/MiMo-V2.6-Distill-Qwen-9B-oQ4e-mtp after strict architecture, geometry, and tokenizer-identity checks. The MTP head is therefore an experimental transplant rather than a restoration of an official XiaomiMiMo tensor.

Validation

Validated locally before upload on 2026-09-25:

  • strict model loading through the oMLX-patched MLX-LM runtime
  • global 5-bit affine quantization metadata with group size 64
  • complete strict oQe importance-matrix application (no missing or mismatched entries)
  • tokenizer SHA-256 identity across source, MTP donor, and output
  • native MTP tensors present and MTP module instantiated
  • official chat template renders an OpenAI-style function schema
  • deterministic generation smoke test (15% of 240 includes 36)

The machine-readable validation report is included as validation.json.

Notes

  • Use a recent oMLX/MLX-LM build with native Qwen3.5 MTP support.
  • Tool use depends on applying the included chat template and supplying tool schemas in the request.
  • Quantization and the transplanted MTP head can change behavior. Evaluate on your own workload before production use.
