Model Card for Ministral-8B-Instruct-2410

We introduce two new state-of-the-art models for local intelligence, on-device computing, and at-the-edge use cases. We call them les Ministraux: Ministral 3B and Ministral 8B.

The Ministral-8B-Instruct-2410 Language Model is an instruct fine-tuned model significantly outperforming existing models of similar size, released under the Mistral Research License.

If you are interested in using Ministral-3B or Ministral-8B commercially, outperforming Mistral-7B, reach out to us.

For more details about les Ministraux please refer to our release blog post.

Ministral 8B Key features

• Released under the Mistral Research License, reach out to us for a commercial license
• Trained with a 128k context window with interleaved sliding-window attention
• Trained on a large proportion of multilingual and code data
• Supports function calling
• Vocabulary size of 131k, using the V3-Tekken tokenizer

Basic Instruct Template (V3-Tekken)

Usage Examples

vLLM (recommended)

We recommend using this model with the vLLM library
to implement production-ready inference pipelines.

IMPORTANT: Currently vLLM is capped at 32k context size because interleaved attention kernels for paged attention are not yet implemented in vLLM.
Attention kernels for paged attention are being worked on and as soon as it is fully supported in vLLM, this model card will be updated.
To take advantage of the full 128k context size we recommend Mistral Inference

_Installation_

Make sure you install vLLM >= v0.6.4:

pip install --upgrade vllm

Also make sure you have mistral_common >= 1.4.4 installed:

pip install --upgrade mistral_common

You can also make use of a ready-to-go docker image.

_Offline_

from vllm import LLM
from vllm.sampling_params import SamplingParams
model_name = "mistralai/Ministral-8B-Instruct-2410"
sampling_params = SamplingParams(max_tokens=8192)
note that running Ministral 8B on a single GPU requires 24 GB of GPU RAM
If you want to divide the GPU requirement over multiple devices, please add e.g. tensor_parallel=2
llm = LLM(model=model_name, tokenizer_mode="mistral", config_format="mistral", load_format="mistral")
prompt = "Do we need to think for 10 seconds to find the answer of 1 + 1?"
messages = [
    {
        "role": "user",
        "content": prompt
    },
]
outputs = llm.chat(messages, sampling_params=sampling_params)
print(outputs[0].outputs[0].text)
You don't need to think for 10 seconds to find the answer to 1 + 1. The answer is 2,

and you can easily add these two numbers in your mind very quickly without any delay.

_Server_

You can also use Ministral-8B in a server/client setting.

Spin up a server:

vllm serve mistralai/Ministral-8B-Instruct-2410 --tokenizer_mode mistral --config_format mistral --load_format mistral

Note: Running Ministral-8B on a single GPU requires 24 GB of GPU RAM.

If you want to divide the GPU requirement over multiple devices, please add e.g. --tensor_parallel=2

And ping the client:

curl --location 'http://<your-node-url>:8000/v1/chat/completions' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer token' \
--data '{
    "model": "mistralai/Ministral-8B-Instruct-2410",
    "messages": [
      {
        "role": "user",
        "content": "Do we need to think for 10 seconds to find the answer of 1 + 1?"
      }
    ]
}'

Mistral-inference

We recommend using mistral-inference to quickly try out / "vibe-check" the model.

_Install_

Make sure to have mistral_inference >= 1.5.0 installed.

pip install mistral_inference --upgrade

_Download_

from huggingface_hub import snapshot_download
from pathlib import Path
mistral_models_path = Path.home().joinpath('mistral_models', '8B-Instruct')
mistral_models_path.mkdir(parents=True, exist_ok=True)
snapshot_download(repo_id="mistralai/Ministral-8B-Instruct-2410", allow_patterns=["params.json", "consolidated.safetensors", "tekken.json"], local_dir=mistral_models_path)

Chat

After installing mistral_inference, a mistral-chat CLI command should be available in your environment. You can chat with the model using

mistral-chat $HOME/mistral_models/8B-Instruct --instruct --max_tokens 256

Passkey detection

IMPORTANT: In this example the passkey message has over >100k tokens and mistral-inference
does not have a chunked pre-fill mechanism. Therefore you will need a lot of
GPU memory in order to run the below example (80 GB). For a more memory-efficient
solution we recommend using vLLM.

from mistral_inference.transformer import Transformer
from pathlib import Path
import json
from mistral_inference.generate import generate
from huggingface_hub import hf_hub_download
from mistral_common.tokens.tokenizers.mistral import MistralTokenizer
from mistral_common.protocol.instruct.messages import UserMessage
from mistral_common.protocol.instruct.request import ChatCompletionRequest
def load_passkey_request() -> ChatCompletionRequest:
    passkey_file = hf_hub_download(repo_id="mistralai/Ministral-8B-Instruct-2410", filename="passkey_example.json")
with open(passkey_file, "r") as f:
        data = json.load(f)
message_content = data["messages"][0]["content"]
    return ChatCompletionRequest(messages=[UserMessage(content=message_content)])
tokenizer = MistralTokenizer.from_file(f"{mistral_models_path}/tekken.json")
model = Transformer.from_folder(mistral_models_path, softmax_fp32=False)
completion_request = load_passkey_request()
tokens = tokenizer.encode_chat_completion(completion_request).tokens
out_tokens, _ = generate([tokens], model, max_tokens=64, temperature=0.0, eos_id=tokenizer.instruct_tokenizer.tokenizer.eos_id)
result = tokenizer.instruct_tokenizer.tokenizer.decode(out_tokens[0])
print(result)  # The pass key is 13005.
