# Voxtral Mini 1.0 (3B) - 2507
|
||
|
||
Voxtral Mini is an enhancement of [Ministral 3B](https://mistral.ai/news/ministraux), incorporating state-of-the-art audio input capabilities while retaining best-in-class text performance. It excels at speech transcription, translation and audio understanding.
|
||
|
||
Learn more about Voxtral in our blog post [here](https://mistral.ai/news/voxtral) and our [research paper](https://arxiv.org/abs/2507.13264).
|
||
|
||
## Key Features
|
||
|
||
Voxtral builds upon Ministral-3B with powerful audio understanding capabilities.
|
||
- **Dedicated transcription mode**: Voxtral can operate in a pure speech transcription mode to maximize performance. By default, Voxtral automatically predicts the source audio language and transcribes the text accordingly
|
||
- **Long-form context**: With a 32k token context length, Voxtral handles audios up to 30 minutes for transcription, or 40 minutes for understanding
|
||
- **Built-in Q&A and summarization**: Supports asking questions directly through audio. Analyze audio and generate structured summaries without the need for separate ASR and language models
|
||
- **Natively multilingual**: Automatic language detection and state-of-the-art performance in the world’s most widely used languages (English, Spanish, French, Portuguese, Hindi, German, Dutch, Italian)
|
||
- **Function-calling straight from voice**: Enables direct triggering of backend functions, workflows, or API calls based on spoken user intents
|
||
- **Highly capable at text**: Retains the text understanding capabilities of its language model backbone, Ministral-3B
|
||
|
||
## Benchmark Results

|
||
|
||
## Usage
|
||
|
||
The model can be used with the following frameworks;
|
||
- [`vllm (recommended)`](https://github.com/vllm-project/vllm): See [here](#vllm-recommended)
|
||
- [`Transformers` 🤗](https://github.com/huggingface/transformers): See [here](#transformers-🤗)
|
||
|
||
**Notes**:
|
||
|
||
- `temperature=0.2` and `top_p=0.95` for chat completion (*e.g. Audio Understanding*) and `temperature=0.0` for transcription
|
||
- Multiple audios per message and multiple user turns with audio are supported
|
||
- System prompts are not yet supported
|
||
|
||
### vLLM (recommended)
|
||
|
||
We recommend using this model with [vLLM](https://github.com/vllm-project/vllm).
|
||
|
||
#### Installation
|
||
|
||
Make sure to install vllm >= 0.10.0, we recommend using `uv`:
|
||
|
||
```
|
||
uv pip install -U "vllm[audio]" --system
|
||
```
|
||
|
||
Doing so should automatically install [`mistral_common >= 1.8.1`](https://github.com/mistralai/mistral-common/releases/tag/v1.8.1).
|
||
|
||
To check:
|
||
```
|
||
python -c "import mistral_common; print(mistral_common.__version__)"
|
||
```
|
||
|
||
#### Offline
|
||
|
||
You can test that your vLLM setup works as expected by cloning the vLLM repo:
|
||
|
||
```sh
|
||
git clone https://github.com/vllm-project/vllm && cd vllm
|
||
```
|
||
|
||
and then running:
|
||
|
||
```sh
|
||
python examples/offline_inference/audio_language.py --num-audios 2 --model-type voxtral
|
||
```
|
||
|
||
#### Serve
|
||
|
||
We recommend that you use Voxtral-Small-24B-2507 in a server/client setting.
|
||
|
||
1. Spin up a server:
|
||
|
||
```
|
||
vllm serve mistralai/Voxtral-Mini-3B-2507 --tokenizer_mode mistral --config_format mistral --load_format mistral
|
||
```
|
||
|
||
**Note:** Running Voxtral-Mini-3B-2507 on GPU requires ~9.5 GB of GPU RAM in bf16 or fp16.
|
||
|
||
|
||
2. To ping the client you can use a simple Python snippet. See the following examples.
|
||
|
||
|
||
### Audio Instruct
|
||
|
||
Leverage the audio capabilities of Voxtral-Mini-3B-2507 to chat.
|
||
|
||
Make sure that your client has `mistral-common` with audio installed:
|
||
|
||
```sh
|
||
pip install --upgrade mistral_common\[audio\]
|
