Voxtral Mini 4B Realtime#

This is a 4-bit quantized MLX conversion of mistralai/Voxtral-Mini-4B-Realtime-2602, Mistral AI's streaming speech-to-text model.

Runs via mlx-audio.

Usage#

pip install mlx-audio[stt]
from mlx_audio.stt.utils import load

model = load("mlx-community/Voxtral-Mini-4B-Realtime-2602-4bit")

# Transcribe audio
result = model.generate("audio.wav")
print(result.text)

# Streaming transcription
for chunk in model.generate("audio.wav", stream=True):
    print(chunk, end="", flush=True)

# Adjust transcription delay (lower = faster but less accurate)
result = model.generate("audio.wav", transcription_delay_ms=480)
SettingValueNotes
Temperature0.0Always use greedy decoding
Transcription delay480msSweet spot of accuracy vs. latency

Architecture#

  • Causal audio encoder (~0.6B) with sliding window attention — enables true streaming
  • Language model decoder (~3.4B) based on Ministral-3B with adaptive RMS norm conditioned on transcription delay
  • 4x downsampling from encoder to decoder (frame rate = 12.5 Hz)
  • Both components use sliding window attention for unbounded audio length
