Mistral 7B's Architectural Innovations

Mistral 7B stands out not just because of its performance but also due to its unique architectural innovations. Let's explore these in detail:

Sliding Window Attention (SWA)

SWA allows each layer of the model to attend to the previous 4,096 hidden states. This mechanism offers a linear compute cost, proportional to the length of the sliding window sequence. The advantage is evident in real-time applications where rapid response times are essential.

Grouped-query Attention (GQA)

GQA is designed to accelerate inference, ensuring that Mistral 7B can respond swiftly, making it suitable for applications that demand real-time interactions.

Setting Up and Deploying Mistral 7B

Mistral 7B offers flexibility in its deployment. Whether you're looking to run it on your local machine or deploy it on a cloud platform, here's a comprehensive guide:

Running Mistral 7B with Docker

For those with a GPU-enabled host, Mistral 7B can be run using Docker. Here's a step-by-step guide:

1. Pull the Docker Image:
   First, you need to pull the Docker image that bundles vLLM, a fast Python inference server, with everything required to run Mistral 7B.

   docker pull ghcr.io/mistralai/harmattan/vllm-public:latest

2. **Run the Model using Docker: Once the image is pulled, you can run the model using the following command:

   docker run --gpus all \
   -e HF_TOKEN=$HF_TOKEN -p 8000:8000 \
   ghcr.io/mistralai/harmattan/vllm-public:latest \
   --host 0.0.0.0 \
   --model mistralai/Mistral-7B-v0.1

   Note: Replace $HF_TOKEN with your Hugging Face user access token.

Direct Deployment with vLLM

For direct deployment, Mistral 7B supports vLLM on GPU-enabled hosts with Cuda 11.8. Here's how to set it up:

1. Installation:
   Install vLLM using pip:

   pip install vllm

2. Login to Hugging Face Hub:
   Before you can use the model, you need to log in to the Hugging Face hub:

   huggingface-cli login

3. Start the Server:
   With the prerequisites in place, initiate the server using the following command:

   python -u -m vllm.entrypoints.openai.api_server --host 0.0.0.0 --model mistralai/Mistral-7B-v0.1

How to Run Mistral 7B Locally

Once Mistral 7B is set up and running, you can interact with it. Detailed steps on how to use the model can be found on the Interacting with the model (opens in a new tab) page. This guide provides insights into sending requests to the model, understanding the responses, and fine-tuning the model for specific tasks.

Setting Up the Environment

Before you can interact with Mistral 7B, you need to set up the environment:

1. Install the OpenAI Python Package:
   This package facilitates interactions with the model.

   pip install openai

2. Configure the OpenAI Module:
   Point the module to the server where Mistral 7B is deployed.

   import openai
   openai.api_base = "http://your-server-ip-or-hostname:8000/v1" 
   openai.api_key = "none"  # vLLM server is not authenticated

Generating Text Completions with Mistral 7B

Mistral 7B can complete given prompts, providing coherent and contextually relevant text. Here's how to trigger a completion:

1. Sample Code for Text Completion:

   completion = openai.Completion.create(
     model="mistralai/Mistral-7B-Instruct-v0.1", 
     prompt="The mistral is",
     temperature=0.7,
     max_tokens=200, 
     stop="."
   )
   print(completion.to_dict_recursive())

   This code will output a completion like:

   {
     'id': 'cmpl-87f6980633bb45f5aecd551bc35335e6',
     'object': 'text_completion',
     'created': 1695651536,
     'model': 'mistralai/Mistral-7B-Instruct-v0.1',
     'choices': [{
       'index': 0,
       'text': ' a cold, dry, northeasterly wind that blows over the Mediterranean Sea',
       'logprobs': None,
       'finish_reason': 'stop'
     }],
     'usage': {'prompt_tokens': 5, 'total_tokens': 23, 'completion_tokens': 18}
   }

Engaging in Interactive Chats

Mistral 7B can also be used for interactive chats, providing conversational responses to user queries.

1. Sample Code for Chat Interaction:

   messages = [{"role": "user", "content": "What is the bash command to list all files in a folder and sort them by last modification?"}]
   chat_completion = openai.ChatCompletion.create(
     model="mistralai/Mistral-7B-Instruct-v0.1",
     temperature=1,
     max_tokens=1024,
     messages=messages
   )

This code initiates a chat with the model, and the model will provide a relevant response to the user's query.

Deploying Mistral 7B with SkyPilot

SkyPilot offers a seamless experience for deploying LLMs like Mistral 7B on various cloud platforms. It promises maximum cost savings, optimal GPU availability, and managed execution. Here's a detailed guide on deploying Mistral 7B using SkyPilot:

SkyPilot Configuration

1. Configuration File Creation:
   Begin by creating a configuration file that instructs SkyPilot on the deployment specifics of your inference server. This will utilize the pre-built docker container provided by Mistral AI. The configuration should look something like this:

   envs:
     MODEL_NAME: mistralai/Mistral-7B-v0.1
   resources: 
     cloud: aws
     accelerators: V100:1
     ports: 
     - 8000
   run: |
     docker run --gpus all -p 8000:8000 ghcr.io/mistralai/harmattan/vllm-public:latest \\
     --host 0.0.0.0 \\
     --model $MODEL_NAME \\
     --tensor-parallel-size $SKYPILOT_NUM_GPUS_PER_NODE

2. Environment Variables Setup:
   You'll need to set specific environment variables so that SkyPilot can fetch both the inference server container and the model weights.

3. Launching the Inference Server:
   With the environment variables in place, you can initiate the inference server using the following command:

   sky launch mistral-7b-v0.1.yaml --region us-east-1

   CAUTION: Deploying in this manner makes the model accessible globally. It's crucial to secure it. You can either expose it exclusively on your private network (modify the --host Docker option), add a load-balancer with an authentication mechanism upfront, or configure your instance networking appropriately.

Usage Quotas and Cloud Providers

It's essential to note that many cloud providers necessitate explicit access requests for powerful GPU instances. For guidance on this, you can refer to SkyPilot's guide (opens in a new tab).
