## Usage Examples |
|
|
|
### vLLM (recommended) |
|
|
|
We recommend using this model with the [vLLM library](https://github.com/vllm-project/vllm) |
|
to implement production-ready inference pipelines. |
|
|
|
**_Installation_** |
|
|
|
Make sure you install `vLLM >= v0.6.1.post1`: |
|
|
|
``` |
|
pip install --upgrade vllm |
|
``` |
|
|
|
Also make sure you have `mistral_common >= 1.4.1` installed: |
|
|
|
``` |
|
pip install --upgrade mistral_common |
|
``` |
|
|
|
You can also make use of a ready-to-go [docker image](https://hub.docker.com/layers/vllm/vllm-openai/latest/images/sha256-de9032a92ffea7b5c007dad80b38fd44aac11eddc31c435f8e52f3b7404bbf39?context=explore). |
|
|
|
|
|
**_Offline_** |
|
|
|
```py |
|
from vllm import LLM |
|
from vllm.sampling_params import SamplingParams |
|
|
|
model_name = "mistralai/Mistral-Small-Instruct-2409" |
|
|
|
sampling_params = SamplingParams(max_tokens=8192) |
|
|
|
# note that running Mistral-Small on a single GPU requires at least 44 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 = "How often does the letter r occur in Mistral?" |
|
|
|
messages = [ |
|
{ |
|
"role": "user", |
|
"content": prompt |
|
}, |
|
] |
|
|
|
outputs = llm.chat(messages, sampling_params=sampling_params) |
|
|
|
print(outputs[0].outputs[0].text) |
|
``` |
|
|
|
**_Server_** |
|
|
|
You can also use Mistral Small in a server/client setting. |
|
|
|
1. Spin up a server: |
|
|
|
|
|
``` |
|
vllm serve mistralai/Mistral-Small-Instruct-2409 --tokenizer_mode mistral --config_format mistral --load_format mistral |
|
``` |
|
|
|
**Note:** Running Mistral-Small on a single GPU requires at least 44 GB of GPU RAM. |
|
|
|
If you want to divide the GPU requirement over multiple devices, please add *e.g.* `--tensor_parallel=2` |
|
|
|
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/Mistral-Small-Instruct-2409", |
|
"messages": [ |
|
{ |
|
"role": "user", |
|
"content": "How often does the letter r occur in Mistral?" |
|
} |
|
] |
|
}' |
|
|
|
``` |
|
|
|
### Mistral-inference |
|
|
|
We recommend using [mistral-inference](https://github.com/mistralai/mistral-inference) to quickly try out / "vibe-check" the model. |
|
|
|
|
|
**_Install_** |
|
|
|
Make sure to have `mistral_inference >= 1.4.1` installed. |
|
|
|
``` |
|
pip install mistral_inference --upgrade |
|
``` |
|
|
|
**_Download_** |
|
|
|
```py |
|
from huggingface_hub import snapshot_download |
|
from pathlib import Path |
|
|
|
mistral_models_path = Path.home().joinpath('mistral_models', '22B-Instruct-Small') |
|
mistral_models_path.mkdir(parents=True, exist_ok=True) |
|
|
|
snapshot_download(repo_id="mistralai/Mistral-Small-Instruct-2409", allow_patterns=["params.json", "consolidated.safetensors", "tokenizer.model.v3"], 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/22B-Instruct-Small --instruct --max_tokens 256 |
|
``` |
|
|
|
### Instruct following |
|
|
|
```py |
|
from mistral_inference.transformer import Transformer |
|
from mistral_inference.generate import generate |
|
|
|
from mistral_common.tokens.tokenizers.mistral import MistralTokenizer |
|
from mistral_common.protocol.instruct.messages import UserMessage |
|
from mistral_common.protocol.instruct.request import ChatCompletionRequest |
|
|
|
|
|
tokenizer = MistralTokenizer.from_file(f"{mistral_models_path}/tokenizer.model.v3") |
|
model = Transformer.from_folder(mistral_models_path) |
|
|
|
completion_request = ChatCompletionRequest(messages=[UserMessage(content="How often does the letter r occur in Mistral?")]) |
|
|
|
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) |
|
``` |
|
|
|
### Function calling |
|
|
|
```py |
|
from mistral_common.protocol.instruct.tool_calls import Function, Tool |
|
from mistral_inference.transformer import Transformer |
|
from mistral_inference.generate import generate |
|
|
|
from mistral_common.tokens.tokenizers.mistral import MistralTokenizer |
|
from mistral_common.protocol.instruct.messages import UserMessage |
|
from mistral_common.protocol.instruct.request import ChatCompletionRequest |
|
|
|
|
|
tokenizer = MistralTokenizer.from_file(f"{mistral_models_path}/tokenizer.model.v3") |
|
model = Transformer.from_folder(mistral_models_path) |
|
|
|
completion_request = ChatCompletionRequest( |
|
tools=[ |
|
Tool( |
|
function=Function( |
|
name="get_current_weather", |
|
description="Get the current weather", |
|
parameters={ |
|
"type": "object", |
|
"properties": { |
|
"location": { |
|
"type": "string", |
|
"description": "The city and state, e.g. San Francisco, CA", |
|
}, |
|
"format": { |
|
"type": "string", |
|
"enum": ["celsius", "fahrenheit"], |
|
"description": "The temperature unit to use. Infer this from the users location.", |
|
}, |
|
}, |
|
"required": ["location", "format"], |
|
}, |
|
) |
|
) |
|
], |
|
messages=[ |
|
UserMessage(content="What's the weather like today in Paris?"), |
|
], |
|
) |
|
|
|
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) |
|
``` |
|
|
|
### Usage in Hugging Face Transformers |
|
|
|
You can also use Hugging Face `transformers` library to run inference using various chat templates, or fine-tune the model. |
|
Example for inference: |
|
|
|
```python |
|
from transformers import LlamaTokenizerFast, MistralForCausalLM |
|
import torch |
|
|
|
device = "cuda" |
|
tokenizer = LlamaTokenizerFast.from_pretrained('mistralai/Mistral-Small-Instruct-2409') |
|
tokenizer.pad_token = tokenizer.eos_token |
|
|
|
model = MistralForCausalLM.from_pretrained('mistralai/Mistral-Small-Instruct-2409', torch_dtype=torch.bfloat16) |
|
model = model.to(device) |
|
|
|
prompt = "How often does the letter r occur in Mistral?" |
|
|
|
messages = [ |
|
{"role": "user", "content": prompt}, |
|
] |
|
|
|
model_input = tokenizer.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_tensors="pt").to(device) |
|
gen = model.generate(model_input, max_new_tokens=150) |
|
dec = tokenizer.batch_decode(gen) |
|
print(dec) |
|
``` |
|
|
|
And you should obtain |
|
```text |
|
<s> |
|
[INST] |
|
How often does the letter r occur in Mistral? |
|
[/INST] |
|
To determine how often the letter "r" occurs in the word "Mistral," |
|
we can simply count the instances of "r" in the word. |
|
The word "Mistral" is broken down as follows: |
|
- M |
|
- i |
|
- s |
|
- t |
|
- r |
|
- a |
|
- l |
|
Counting the "r"s, we find that there is only one "r" in "Mistral." |
|
Therefore, the letter "r" occurs once in the word "Mistral." |
|
</s> |
|
``` |
