Part of the MiMo V2.5 ASR MLX collection.

MiMo-V2.5-ASR-MLX-bf16 (MLX)

Apple MLX weights for XiaomiMiMo/MiMo-V2.5-ASR, converted for local ASR on Apple Silicon.

TL;DR


Variant	bfloat16
Best for	high-quality Apple Silicon use
Official code	`XiaomiMiMo/MiMo-V2.5-ASR`
MLX helper	`ailuntx/MiMo-V2.5-ASR-MLX`
MLX runtime dependency	`ailuntx/mlx-audio`
Audio tokenizer	`mlx-community/MiMo-Audio-Tokenizer`
Hardware	Apple Silicon recommended; HF Spaces CPU fallback is only a load smoke test

Quick Start

bash

git clone https://github.com/ailuntx/MiMo-V2.5-ASR-MLX.git
cd MiMo-V2.5-ASR-MLX
python -m venv .venv
.venv/bin/pip install git+https://github.com/ailuntx/mlx-audio.git

hf download mlx-community/MiMo-Audio-Tokenizer --local-dir ./models/MiMo-Audio-Tokenizer
hf download mlx-community/MiMo-V2.5-ASR-MLX-bf16 --local-dir ./models/MiMo-V2.5-ASR-MLX-bf16

.venv/bin/python run_mimo_asr_mlx.py \
  --model ./models/MiMo-V2.5-ASR-MLX-bf16 \
  --audio path/to/audio.wav

Variants

Variant	Best for
`MiMo-V2.5-ASR-MLX`	default entry
`MiMo-V2.5-ASR-MLX-fp32`	high-precision baseline
`MiMo-V2.5-ASR-MLX-bf16`	high-quality Apple Silicon use
`MiMo-V2.5-ASR-MLX-8bit`	smaller local checkpoint
`MiMo-V2.5-ASR-MLX-4bit`	smallest checkpoint

Conversion Notes

Component	Source	MLX handling
ASR model	`XiaomiMiMo/MiMo-V2.5-ASR`	converted to MLX weights
audio tokenizer	`mlx-community/MiMo-Audio-Tokenizer`	downloaded separately and passed to the runtime
helper script	`ailuntx/MiMo-V2.5-ASR-MLX`	wraps `mlx-audio` loading/generation

Validation

Local Apple Silicon is the intended runtime. The HF Space can start and load the model on Linux CPU fallback, but full ASR on cpu-basic can exceed request timeouts.
