Qwen3-8B · MiMo Music GRPO — GGUF

Code, logs and all results: https://github.com/PromptEngineer48/mimo-music-grpo

GGUF builds of Prompt48/Qwen3-8B-MiMo-Music-GRPO

(Qwen3-8B trained with GRPO on Xiaomi's open-sourced MiMo-V2.6 music environment). See that page for results and limitations.

Use Q8_0. Measured on the same 40 held-out prompts × 4 samples, Xiaomi's strict grader:

| Version | Size | Valid music | Mean score |

|---|---|---|---|

| Base Qwen3-8B (before RL) | — | 0.6% | 0.002 |

| Merged bf16 (vLLM) | 16 GB | 14.4% | 0.050 |

| qwen3-8b-mimo-music-grpo-Q8_0.gguf | 8.7 GB | 18.8% | 0.071 |

| qwen3-8b-mimo-music-grpo-Q4_K_M.gguf | 5.0 GB | 5.0% | 0.015 |

Q4_K_M loses most of the RL gain (the learned behaviour is fragile at 4-bit). It still fits 8 GB GPUs, but expect far fewer valid pieces.

Prompting matters: it was trained on long, detailed composition briefs (key, tempo, meter, instrumentation, bars, structure),

like the ones in XiaomiMiMo/MiMo-V2.6-RL-oss (music subset). Short prompts give short, repetitive output.
