# Ministral 3 14B Base 2512
The largest model in the Ministral 3 family, **Ministral 3 14B** offers frontier capabilities and performance comparable to its larger [Mistral Small 3.2 24B](https://huggingface.co/mistralai/Mistral-Small-3.2-Instruct-2506) counterpart. A powerful and efficient language model with vision capabilities.

This model is the base pre-trained version, not fine-tuned for instruction or reasoning tasks, making it ideal for custom post-training processes.  
For instruction and chat based use cases, we recommend using [Ministral 3 14B Instruct 2512](https://huggingface.co/mistralai/Ministral-3-14B-Instruct-2512).

The Ministral 3 family is designed for edge deployment, capable of running on a wide range of hardware. Ministral 3 14B can even be deployed locally, fitting in 32GB of VRAM in BF16, and less than 24GB of RAM/VRAM when quantized.

## Key Features
Ministral 3 14B consists of two main architectural components:
- **13.5B Language Model**
- **0.4B Vision Encoder**

The Ministral 3 14B Base model offers the following capabilities:
- **Vision**: Enables the model to analyze images and provide insights based on visual content, in addition to text.
- **Multilingual**: Supports dozens of languages, including English, French, Spanish, German, Italian, Portuguese, Dutch, Chinese, Japanese, Korean, Arabic.
- **Edge-Optimized**: Delivers best-in-class performance at a small scale, deployable anywhere.
- **Apache 2.0 License**: Open-source license allowing usage and modification for both commercial and non-commercial purposes.
- **Large Context Window**: Supports a 256k context window.

### Use Cases
Private AI deployments where advanced capabilities meet practical hardware constraints:
- Private/custom chat and AI assistant deployments in constrained environments
- Advanced local agentic use cases
- Fine-tuning and specialization
- And more...
  
Bringing advanced AI capabilities to most environments.

## Usage

The model can be used with the following frameworks;
- [`vllm`](https://github.com/vllm-project/vllm): See [here](#vllm)
- [`transformers`](https://github.com/huggingface/transformers): See [here](#transformers)
  
### vLLM

We recommend using this model with [vLLM](https://github.com/vllm-project/vllm).

#### Installation

Make sure to install **vllm >= 1.12.0**:

```
pip install vllm --upgrade
```

Doing so should automatically install [`mistral_common >= 1.8.6`](https://github.com/mistralai/mistral-common/releases/tag/v1.8.6).

To check:
```
python -c "import mistral_common; print(mistral_common.__version__)"
```

You can also make use of a ready-to-go [docker image](https://github.com/vllm-project/vllm/blob/main/docker/Dockerfile) or on the [docker hub](https://hub.docker.com/layers/vllm/vllm-openai/latest).

#### Serve

To fully exploit the `Ministral-3-14B-Base-2512` we recommed using 2xH200 GPUs for deployment due to its large context. However if you don't need a large context, you can fall back to a single GPU.

A simple launch command is:

```bash
vllm serve mistralai/Ministral-3-14B-Base-2512 --tensor-parallel-size 2 \
  --tokenizer_mode mistral --config_format mistral --load_format mistral
```

Additional flags:

* You can set `--max-model-len` to preserve memory. By default it is set to `262144` which is quite large but not necessary for most scenarios.
* You can set `--max-num-batched-tokens` to balance throughput and latency, higher means higher throughput but higher latency.

#### Usage of the model

Here we asumme that the model `mistralai/Ministral-3-14B-Base-2512` is served and you can ping it to the domain `localhost` with the port `8000` which is the default for vLLM.

<details>
  <summary>Test Base</summary>

Quick test with the base model.

```python
from openai import OpenAI

# Modify OpenAI's API key and API base to use vLLM's API server.
openai_api_key = "EMPTY"
openai_api_base = "http://localhost:8000/v1"

TEMP = 0.15
MAX_TOK = 256

client = OpenAI(
    api_key=openai_api_key,
    base_url=openai_api_base,
)

models = client.models.list()
model = models.data[0].id

response = client.completions.create(
    model=model,
    prompt="What is the best thing in the universe ?",
    temperature=TEMP,
    max_tokens=MAX_TOK,
)

print(response.choices[0].text)
```

</details>

### Transformers

You can also use Ministral 3 14B Base 2512 with `Transformers` !
Make sure to install `Transformers` from its first v5 release candidate or from "main":

```
pip install transformers==5.0.0rc0
```

To make the best use of our model with `Transformers` make sure to have [installed](https://github.com/mistralai/mistral-common) `mistral-common >= 1.8.6` to use our tokenizer.

```bash
pip install mistral-common --upgrade
```

Then load our tokenizer along with the model and generate:

<details>
  <summary>Python snippet</summary>

```python
from transformers import Mistral3ForConditionalGeneration, MistralCommonBackend, FineGrainedFP8Config

model_id = "mistralai/Ministral-3-14B-Base-2512"
model = Mistral3ForConditionalGeneration.from_pretrained(
    model_id,
    device_map="auto",
)
tokenizer = MistralCommonBackend.from_pretrained(model_id)

input_ids = tokenizer.encode("Once about a time, France was a", return_tensors="pt")
input_ids = input_ids.to("cuda")

output = model.generate(
    input_ids,
    max_new_tokens=30,
)[0]

decoded_output = tokenizer.decode(output[len(input_ids[0]):])
print(decoded_output)
```
