This model is the instruct post-trained version in **FP8**, fine-tuned for instruction tasks, making it ideal for chat and instruction based use cases. The Ministral 3 family is designed for edge deployment, capable of running on a wide range of hardware. Ministral 3 3B can even be deployed locally, capable of fitting in 8GB of VRAM in FP8, and less if further quantized. Learn more in our [blog post](https://mistral.ai/news/mistral-3) and [paper](https://arxiv.org/abs/2601.08584). ## Key Features Ministral 3 3B consists of two main architectural components: - **3.4B Language Model** - **0.4B Vision Encoder** The Ministral 3 3B Instruct 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. - **System Prompt**: Maintains strong adherence and support for system prompts. - **Agentic**: Offers best-in-class agentic capabilities with native function calling and JSON outputting. - **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 Ideal for lightweight, real-time applications on edge or low-resource devices, such as: - Image captioning - Text classification - Real-time efficient translation - Data extraction - Short content generation - Fine-tuning and specialization - And more... Bringing advanced AI capabilities to edge and distributed environments for embedded systems. ### Recommended Settings We recommend deploying with the following best practices: - System Prompt: Define a clear environment and use case, including guidance on how to effectively leverage tools in agentic systems. - Sampling Parameters: Use a **temperature below 0.1** for daily-driver and production environments ; Higher temperatures may be explored for creative use cases - developers are encouraged to experiment with alternative settings. - Tools: Keep the set of tools well-defined and limit their number to the minimum required for the use case - Avoiding overloading the model with an excessive number of tools. - Vision: When deploying with vision capabilities, we recommend maintaining an aspect ratio close to 1:1 (width-to-height) for images. Avoiding the use of overly thin or wide images - crop them as needed to ensure optimal performance. ### Recommended Sampling * We recommend starting with a Temperature of 0.1 for most use cases. Feel free to experiment with different settings to best suit your specific needs. ## Ministral 3 Family | Model Name | Type | Precision | Link | |--------------------------------|--------------------|-----------|------------------------------------------------------------------------------------------| | Ministral 3 3B Base 2512 | Base pre-trained | BF16 | [Hugging Face](https://huggingface.co/mistralai/Ministral-3-3B-Base-2512) | | **Ministral 3 3B Instruct 2512** | **Instruct post-trained** | **FP8** | [**Hugging Face**](https://huggingface.co/mistralai/Ministral-3-3B-Instruct-2512) | | Ministral 3 3B Reasoning 2512 | Reasoning capable | BF16 | [Hugging Face](https://huggingface.co/mistralai/Ministral-3-3B-Reasoning-2512) | | Ministral 3 8B Base 2512 | Base pre-trained | BF16 | [Hugging Face](https://huggingface.co/mistralai/Ministral-3-8B-Base-2512) | | Ministral 3 8B Instruct 2512 | Instruct post-trained | FP8 | [Hugging Face](https://huggingface.co/mistralai/Ministral-3-8B-Instruct-2512) | | Ministral 3 8B Reasoning 2512 | Reasoning capable | BF16 | [Hugging Face](https://huggingface.co/mistralai/Ministral-3-8B-Reasoning-2512) | | Ministral 3 14B Base 2512 | Base pre-trained** | BF16 | [Hugging Face](https://huggingface.co/mistralai/Ministral-3-14B-Base-2512) | | Ministral 3 14B Instruct 2512 | Instruct post-trained | FP8 | [Hugging Face](https://huggingface.co/mistralai/Ministral-3-14B-Instruct-2512) | | Ministral 3 14B Reasoning 2512 | Reasoning capable | BF16 | [Hugging Face](https://huggingface.co/mistralai/Ministral-3-14B-Reasoning-2512) | Other formats available [here](https://huggingface.co/collections/mistralai/ministral-3-additional-checkpoints). ## Benchmark Results We compare Ministral 3 to similar sized models. ### Reasoning | Model | AIME25 | AIME24 | GPQA Diamond | LiveCodeBench | |---------------------------|-------------|-------------|--------------|---------------| | **Ministral 3 14B** | 0.850| 0.898| 0.712 | 0.646 | | Qwen3-14B (Thinking) | 0.737 | 0.837 | 0.663 | 0.593 | | | | | | | | **Ministral 3 8B** | 0.787 | 0.860| 0.668 | 0.616 | | Qwen3-VL-8B-Thinking | 0.798| 0.860| 0.671 | 0.580 | | | | | | | | **Ministral 3 3B** | 0.721| 0.775| 0.534 | 0.548 | | Qwen3-VL-4B-Thinking | 0.697 | 0.729 | 0.601 | 0.513 | ### Instruct | Model | Arena Hard | WildBench | MATH Maj@1 | MM MTBench | |---------------------------|-------------|------------|-------------|------------------| | **Ministral 3 14B** | 0.551| 68.5| 0.904| 8.49 | | Qwen3 14B (Non-Thinking) | 0.427 | 65.1 | 0.870 | NOT MULTIMODAL | | Gemma3-12B-Instruct | 0.436 | 63.2 | 0.854 | 6.70 | | | | | | | | **Ministral 3 8B** | 0.509 | 66.8| 0.876 | 8.08 | | Qwen3-VL-8B-Instruct | 0.528| 66.3 | 0.946| 8.00 | | | | | | | | **Ministral 3 3B** | 0.305 | 56.8| 0.830 | 7.83 | | Qwen3-VL-4B-Instruct | 0.438| 56.8| 0.900| 8.01 | | Qwen3-VL-2B-Instruct | 0.163 | 42.2 | 0.786 | 6.36 | | Gemma3-4B-Instruct | 0.318 | 49.1 | 0.759 | 5.23 | ### Base | Model | Multilingual MMLU | MATH CoT 2-Shot | AGIEval 5-shot | MMLU Redux 5-shot | MMLU 5-shot | TriviaQA 5-shot | |---------------------|-------------------|-----------------|----------------|-------------------|-------------|-----------------| | **Ministral 3 14B** | 0.742 | 0.676 | 0.648 | 0.820 | 0.794 | 0.749 | | Qwen3 14B Base | 0.754 | 0.620 | 0.661 | 0.837 | 0.804| 0.703 | | Gemma 3 12B Base | 0.690 | 0.487 | 0.587 | 0.766 | 0.745 | 0.788 | | | | | | | | | | **Ministral 3 8B** | 0.706 | 0.626 | 0.591 | 0.793 | 0.761| 0.681 | | Qwen 3 8B Base | 0.700 | 0.576 | 0.596 | 0.794 | 0.760 | 0.639 | | | | | | | | | | **Ministral 3 3B** | 0.652 | 0.601 | 0.511 | 0.735 | 0.707 | 0.592 | | Qwen 3 4B Base | 0.677 | 0.405 | 0.570 | 0.759 | 0.713| 0.530 | | Gemma 3 4B Base | 0.516 | 0.294 | 0.430 | 0.626 | 0.589 | 0.640 | ## 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 >= 0.12.0**: ``` 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 Due to their size and the FP8 format of their weights `Ministral-3-3B-Instruct-2512`, `Ministral-3-8B-Instruct-2512` and `Ministral-3-14B-Instruct-2512` can run on a single 1xH200 GPU. A simple launch command is: ```bash vllm serve mistralai/Ministral-3-3B-Instruct-2512 \ --tokenizer_mode mistral --config_format mistral --load_format mistral \ --enable-auto-tool-choice --tool-call-parser mistral ``` Key parameter notes: * enable-auto-tool-choice: Required when enabling tool usage. * tool-call-parser mistral: Required when enabling tool usage. 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 assume that the model `mistralai/Ministral-3-3B-Instruct-2512` is served and you can ping it to the domain `localhost` with the port `8000` which is the default for vLLM.
Vision Reasoning Let's see if the Ministral 3 knows when to pick a fight ! ```python from datetime import datetime, timedelta from openai import OpenAI from huggingface_hub import hf_hub_download # 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 = 262144 client = OpenAI( api_key=openai_api_key, base_url=openai_api_base, ) models = client.models.list() model = models.data[0].id def load_system_prompt(repo_id: str, filename: str) -> str: file_path = hf_hub_download(repo_id=repo_id, filename=filename) with open(file_path, "r") as file: system_prompt = file.read() today = datetime.today().strftime("%Y-%m-%d") yesterday = (datetime.today() - timedelta(days=1)).strftime("%Y-%m-%d") model_name = repo_id.split("/")[-1] return system_prompt.format(name=model_name, today=today, yesterday=yesterday) SYSTEM_PROMPT = load_system_prompt(model, "SYSTEM_PROMPT.txt") image_url = "https://static.wikia.nocookie.net/essentialsdocs/images/7/70/Battle.png/revision/latest?cb=20220523172438" messages = [ {"role": "system", "content": SYSTEM_PROMPT}, { "role": "user", "content": [ { "type": "text", "text": "What action do you think I should take in this situation?
