Usage Examples
vLLM (recommended)
We recommend using this model with the vLLM library to implement production-ready inference pipelines.
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 >= v0.6.2:
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
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.
