Setting Up a Local AI Environment

In the realm of sensitive data processing, establishing a secure and isolated environment for AI operations is paramount. Air-gapping, the practice of physically isolating a system from external networks, offers an unparalleled level of security for handling sensitive documents and data. By setting up a local AI environment within an air-gapped network, organizations can leverage the power of artificial intelligence while ensuring the utmost confidentiality and integrity of their sensitive information.

First install our dependencies

pip install llama-index llama-index-embeddings-huggingface

Create a function to initialize our documents

def createVectorIndex(path):
    PERSIST_DIR = "./storage"
    # load the documents and create the index
    documents = SimpleDirectoryReader(path).load_data()
    if not os.path.exists(PERSIST_DIR):
        index = VectorStoreIndex.from_documents(documents, embed_model='local')
        # store it for later
        index.storage_context.persist(persist_dir=PERSIST_DIR)
    else:
        # load the existing index
        storage_context = StorageContext.from_defaults(persist_dir=PERSIST_DIR)
        index = load_index_from_storage(storage_context, embed_model='local')
    return index, documents

Create our index by calling the function by pointing our path to the location of the directory where our sensitive documents are stored.

vectorIndex = createVectorIndex('./sensitive_documents')

Now that we have a vector index of our sensitive documents, we can analyze them using a local LLM. You can run a local LLM many different ways like Llama.cpp, Ollama, or GPT4ALL. For this tutorial we will be using LM Studio which is very easy to use, has a GUI, list of the latest models, and makes downloading and running really easy. The added benefit of using this interface is that it already has Apple Silicon improvements built in when running a supported model. Once LM Studio is installed on your system, you can select a model from the list that will run optimally on your system, and leaves enough memory for a large context window.

I chose the Mistral 8x7b 2 bit k-quantization for my M2 MacBook Pro with 32GB RAM.

Next, we will start the model in local API mode so we can reach it from our python code. First we need to load the model into RAM.

Then start the Local Inference Server.

Now we can initialize the LLM in our python code using the llama-index OpenAI class. This class can be used because the LM Studio uses a OpenAI compatible interface when running the inference server. If you do not feel comfortable using this class, you could always define your own custom llm with llama-index.

from llama_index.llms.openai import OpenAI

llm = OpenAI(api_base="http://localhost:1234/v1", api_key='not-needed')
query_engine = vector_index.as_query_engine(llm=llm)

Now you are ready to ask questions about your sensitive documents and get detailed answers!

result = query_engine.query("What are the key takeaways from the Q4 financial reports?")
print(result)
