Usage

The model can be used with the following frameworks;


Note 1: We recommend using a relatively low temperature, such as temperature=0.15.

Note 2: Make sure to add a system prompt to the model to best tailor it to your needs. If you want to use the model as a general assistant, we recommend to use the one provided in the SYSTEM_PROMPT.txt file.

vLLM (recommended)

We recommend using this model with vLLM.

Installation

Make sure to install vLLM >= 0.9.1:

pip install vllm --upgrade

Doing so should automatically install mistral_common >= 1.6.2.

To check:

python -c "import mistral_common; print(mistral_common.__version__)"

You can also make use of a ready-to-go docker image or on the docker hub.

Serve

We recommend that you use Mistral-Small-3.2-24B-Instruct-2506 in a server/client setting.

  • Spin up a server:
  • vllm serve mistralai/Mistral-Small-3.2-24B-Instruct-2506 \
      --tokenizer_mode mistral --config_format mistral \
      --load_format mistral --tool-call-parser mistral \
      --enable-auto-tool-choice --limit-mm-per-prompt '{"image":10}' \
      --tensor-parallel-size 2
    Note: Running Mistral-Small-3.2-24B-Instruct-2506 on GPU requires ~55 GB of GPU RAM in bf16 or fp16.

    Python snippet
    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 = 131072

    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)

    model_id = "mistralai/Mistral-Small-3.2-24B-Instruct-2506"
    SYSTEM_PROMPT = load_system_prompt(model_id, "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? List all the possible actions and explain why you think they are good or bad.",
    },
    {"type": "image_url", "image_url": {"url": image_url}},
    ],
    },
    ]

    response = client.chat.completions.create(

    messages=messages,
    temperature=TEMP,
    max_tokens=MAX_TOK,
    )

    print(response.choices[0].message.content)

    In this situation, you are playing a Pokémon game where your Pikachu (Level 42) is facing a wild Pidgey (Level 17). Here are the possible actions you can take and an analysis of each:

    1. FIGHT:

    - Pros: Pikachu is significantly higher level than the wild Pidgey, which suggests that it should be able to defeat Pidgey easily. This could be a good opportunity to gain experience points and possibly items or money.

    - Cons: There is always a small risk of Pikachu fainting, especially if Pidgey has a powerful move or a status effect that could hinder Pikachu. However, given the large level difference, this risk is minimal.

    2. BAG:

    - Pros: You might have items in your bag that could help in this battle, such as Potions, Poké Balls, or Berries. Using an item could help you capture the Pidgey or heal your Pikachu if needed.

    - Cons: Using items might not be necessary given the level difference. It could be more efficient to just fight and defeat the Pidgey quickly.

    3. POKÉMON:

    - Pros: You might have another Pokémon in your party that is better suited for this battle or that you want to gain experience. Switching Pokémon could also be a strategic move if you want to train a lower-level Pokémon.

    - Cons: Switching Pokémon might not be necessary since Pikachu is at a significant advantage. It could also waste time and potentially give Pidgey a turn to attack.

    4. RUN:

    - Pros: Running away could save time and conserve your Pokémon's health and resources. If you are in a hurry or do not need the experience or items, running away is a safe option.

    - Cons: Running away means you miss out on the experience points and potential items or money that you could gain from defeating the Pidgey. It also means you do not get the chance to capture the Pidgey if you wanted to.

    ### Recommendation:

    Given the significant level advantage, the best action is likely to FIGHT. This will allow you to quickly defeat the Pidgey, gain experience points, and potentially earn items or money. If you are concerned about Pikachu's health, you could use an item from your BAG to heal it before or during the battle. Running away or switching Pokémon does not seem necessary in this situation.

    Instruction following

    Mistral-Small-3.2-24B-Instruct-2506 will follow your instructions down to the last letter !

    Python snippet
    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

    "Always brave cats dance elegantly, fluffy giraffes happily ignore jungle kites, lovingly munching nuts, observing playful quails racing swiftly, tiny unicorns vaulting while xylophones yodel zealously."

    This sentence follows the sequence from A to Z without skipping any letters.

    Transformers

    You can also use Mistral-Small-3.2-24B-Instruct-2506 with Transformers !

    To make the best use of our model with Transformers make sure to have installed mistral-common >= 1.6.2 to use our tokenizer.

    pip install mistral-common --upgrade

    Then load our tokenizer along with the model and generate:

    Python snippet
    from datetime import datetime, timedelta
    import torch
    

    from mistral_common.protocol.instruct.request import ChatCompletionRequest
    from mistral_common.tokens.tokenizers.mistral import MistralTokenizer

    ],
    },
    ]

    tokenized = tokenizer.encode_chat_completion(ChatCompletionRequest(messages=messages))

    input_ids = torch.tensor([tokenized.tokens])
    attention_mask = torch.ones_like(input_ids)
    pixel_values = torch.tensor(tokenized.images[0], dtype=torch.bfloat16).unsqueeze(0)

    )[0]

    decoded_output = tokenizer.decode(output[len(tokenized.tokens) :])
    print(decoded_output)

    In this situation, you are playing a Pokémon game where your Pikachu (Level 42) is facing a wild Pidgey (Level 17). Here are the possible actions you can take and an analysis of each:

    1. FIGHT:

    - Pros: Pikachu is significantly higher level than the wild Pidgey, which suggests that it should be able to defeat Pidgey easily. This could be a good opportunity to gain experience points and possibly items or money.

    - Cons: There is always a small risk of Pikachu fainting, especially if Pidgey has a powerful move or a status effect that could hinder Pikachu. However, given the large level difference, this risk is minimal.

    - Cons: Using items might not be necessary given the level difference. It could be more efficient to just fight and defeat Pidgey quickly.

    3. POKÉMON:

    - Pros: You might have another Pokémon in your party that is better suited for this battle or that you want to gain experience. Switching Pokémon could also be strategic if you want to train a lower-level Pokémon.

    - Cons: Switching Pokémon might not be necessary since Pikachu is at a significant advantage. It could also waste time and potentially give Pidgey a turn to attack.

    4. RUN:

    - Pros: Running away could be a quick way to avoid the battle altogether. This might be useful if you are trying to conserve resources or if you are in a hurry to get to another location.

    - Cons: Running away means you miss out on the experience points, items, or money that you could gain from defeating Pidgey. It also might not be the most efficient use of your time if you are trying to train your Pokémon.

    ### Recommendation:

    Given the significant level advantage, the best action to take is likely FIGHT. This will allow you to quickly defeat Pidgey and gain experience points for Pikachu. If you are concerned about Pikachu's health, you could use the BAG to heal Pikachu before or during the battle. Running away or switching Pokémon does not seem necessary in this situation.
