Part 3. How to Run Mixtral 8x7b Locally with LlamaIndex and Ollama

How to Run Mixtral 8x7b Locally

The European AI powerhouse Mistral AI recently unveiled its "mixture of experts" model, Mixtral 8x7b. This model, featuring eight experts each trained with 7 billion parameters, has sparked significant interest for matching or even surpassing the performance of GPT-3.5 and Llama2 70b across various benchmarks.

Step 1: Install Ollama

Ollama, an open-source tool available for MacOS, Linux, and Windows (via Windows Subsystem For Linux), simplifies the process of running local models. With Ollama, you can initiate Mixtral with a single command:

ollama run mixtral

This command downloads the model (which might take some time) and requires a significant amount of RAM (48GB) to run smoothly. For systems with lower specs, Mistral 7b is a viable alternative.

Step 2: Install Dependencies

To integrate Mixtral with LlamaIndex, you'll need several dependencies. Install them using pip:

pip install llama-index qdrant_client torch transformers

Step 3: Smoke Test

Verify the setup with a "smoke test" using Ollama and LlamaIndex:

from llama_index.llms import Ollama
llm = Ollama(model="mixtral")
response = llm.complete("Who is Laurie Voss?")

Step 4: Load Data and Index It

Preparing Data:

Use any dataset for this example; here, we use a collection of tweets. Qdrant, an open-source vector database, stores the data. The following code snippets showcase the process of loading and indexing the data with Qdrant and LlamaIndex:

from pathlib import Path
import qdrant_client
from llama_index import VectorStoreIndex, ServiceContext, download_loader
from llama_index.llms import Ollama
from llama_index.storage.storage_context import StorageContext
from llama_index.vector_stores.qdrant import QdrantVectorStore
## Initialize Qdrant and load tweets
client = qdrant_client.QdrantClient(path="./qdrant_data")
vector_store = QdrantVectorStore(client=client, collection_name="tweets")
storage_context = StorageContext.from_defaults(vector_store=vector_store)
## Set up Service Context with Mixtral and embed locally
llm = Ollama(model="mixtral")
service_context = ServiceContext.from_defaults(llm=llm, embed_model="local")
## Index and query data
index = VectorStoreIndex.from_documents(documents, service_context=service_context, storage_context=storage_context)
query_engine = index.as_query_engine()
response = query_engine.query("What does the author think about Star Trek? Give details.")

Verifying the Index:

The final step involves using the pre-built index to answer queries. This process does not require reloading the data as it's already indexed in Qdrant:

import qdrant_client
from llama_index import VectorStoreIndex, ServiceContext
from llama_index.llms import Ollama
from llama_index.vector_stores.qdrant import QdrantVectorStore
## Load the vector store and Mixtral
client = qdrant_client.QdrantClient(path="./qdrant_data")
vector_store = QdrantVectorStore(client=client, collection_name="tweets")
llm = Ollama(model="mixtral")
service_context = ServiceContext.from_defaults(llm=llm, embed_model="local")
## Load index and query
index = VectorStoreIndex.from_vector_store(vector_store=vector_store, service_context=service_context)
query_engine = index.as_query_engine(similarity_top_k=20)
response = query_engine.query("Does the author like SQL? Give details.")
