Providing enterprise-grade LLM-based development framework, tools, and fine-tuned models.

llmware

llmware is a unified, open, extensible framework for LLM-based application patterns including Retrieval Augmented Generation (RAG). This project provides a comprehensive set of tools that anyone can use – from beginner to the most sophisticated AI developer – to rapidly build industrial-grade enterprise LLM-based applications. Key differentiators include: source citation for Q & A scenarios, fact checking, and other guardrails for model hallucination.

With llmware, our goal is to contribute to and help catalyze an open community around the new combination of open, extensible technologies being assembled to accomplish fact-based generative workflows.

🎯 Key features

llmware is an integrated framework comprised of four major components:

Retrieval: Assemble fact-sets

A comprehensive set of querying methods: semantic, text, and hybrid retrieval with integrated metadata.
Ranking and filtering strategies to enable semantic search and rapid retrieval of information.
Web scrapers, Wikipedia integration, and Yahoo Finance API integration as additional tools to assemble fact-sets for generation.

Prompt: Tools for sophisticated generative scenarios

Connect Models: Open interface designed to support AI21, Ai Bloks READ-GPT, Anthropic, Cohere, HuggingFace Generative models, llmware BLING and DRAGON models, OpenAI.
Prepare Sources: Tools for packaging and tracking a wide range of materials into model context window sizes. Sources include files, websites, audio, AWS Transcribe transcripts, Wikipedia and Yahoo Finance.
Prompt Catalog: Dynamically configurable prompts to experiment with multiple models without any change in the code.
Post Processing: a full set of metadata and tools for evidence verification, classification of a response, and fact-checking.
Human in the Loop: Ability to enable user ratings, feedback, and corrections of AI responses.
Auditability: A flexible state mechanism to capture, track, analyze and audit the LLM prompt lifecycle

Vector Embeddings: swappable embedding models and vector databases

Custom trained sentence transformer embedding models and support for embedding models from Cohere, Google, HuggingFace Embedding models, and OpenAI.
Mix-and-match among multiple options to find the right solution for any particular application.
Out-of-the-box support for 3 vector databases - Milvus, FAISS, and Pinecone.

Parsing and Text Chunking: Prepare your data for RAG

Parsers for: PDF, PowerPoint, Word, Excel, HTML, Text, WAV, AWS Transcribe transcripts.
A complete set of text-chunking tools to separate information and associated metadata to a consistent block format.

📚 Explore additional llmware capabilities and 🎬 Check out these videos on how to quickly get started with RAG:

🌱 Getting Started

1. Install llmware:

pip install llmware

python3 -m pip install llmware

See Working with llmware for other options to get up and running.

2. MongoDB and Milvus

MongoDB and Milvus are optional and used to provide production-grade database and vector embedding capabilities. The fastest way to get started is to use the provided Docker Compose file which takes care of running them both:

curl -o docker-compose.yaml https://raw.githubusercontent.com/llmware-ai/llmware/main/docker-compose.yaml

and then run the containers:

docker compose up -d

Not ready to install MongoDB or Milvus? Check out what you can do without them in our examples section.

See Running MongoDB and Milvus for other options to get up and running with these optional dependencies.

3. 🔥 Start coding - Quick Start For RAG 🔥

# This example demonstrates Retrieval Augmented Retrieval (RAG):
import os
from llmware.library import Library
from llmware.retrieval import Query
from llmware.prompts import Prompt
from llmware.setup import Setup

# Update this value with your own API Key, either by setting the env var or editing it directly here:
openai_api_key = os.environ["OPENAI_API_KEY"]

# A self-contained end-to-end example of RAG
def end_to_end_rag():
    
    # Create a library called "Agreements", and load it with llmware sample files
    print (f"\n > Creating library 'Agreements'...")
    library = Library().create_new_library("Agreements")
    sample_files_path = Setup().load_sample_files()
    library.add_files(os.path.join(sample_files_path,"Agreements"))

    # Create vector embeddings for the library using the "industry-bert-contracts model and store them in Milvus
    print (f"\n > Generating vector embeddings using embedding model: 'industry-bert-contracts'...")
    library.install_new_embedding(embedding_model_name="industry-bert-contracts", vector_db="milvus")

    # Perform a semantic search against our library.  This will gather evidence to be used in the LLM prompt
    print (f"\n > Performing a semantic query...")
    os.environ["TOKENIZERS_PARALLELISM"] = "false" # Avoid a HuggingFace tokenizer warning
    query_results = Query(library).semantic_query("Termination", result_count=20)

    # Create a new prompter using the GPT-4 and add the query_results captured above
    prompt_text = "Summarize the termination provisions"
    print (f"\n > Prompting LLM with '{prompt_text}'")
    prompter = Prompt().load_model("gpt-4", api_key=openai_api_key)
    sources = prompter.add_source_query_results(query_results)

    # Prompt the LLM with the sources and a query string
    responses = prompter.prompt_with_source(prompt_text, prompt_name="summarize_with_bullets")
    for response in responses:
        print ("\n > LLM response\n" + response["llm_response"])
    
    # Finally, generate a CSV report that can be shared
    print (f"\n > Generating CSV report...")
    report_data = prompter.send_to_human_for_review()
    print ("File: " + report_data["report_fp"] + "\n")

end_to_end_rag()

4. Accessing LLMs and setting-up API keys & secrets

To get started with a proprietary model, you need to provide your own API Keys. If you don't yet have one, more information can be found at: AI21, Ai Bloks, Anthropic, Cohere, Google, OpenAI.

API keys and secrets for models, aws, and pinecone can be set-up for use in environment variables or managed however you prefer.

You can also access the llmware public model repository which includes out-of-the-box custom trained sentence transformer embedding models fine-tuned for the following industries: Insurance, Contracts, Asset Management, SEC. These domain specific models along with llmware's generative BLING model series ("Best Little Instruction-following No-GPU-required") and DRAGON model series ("Delivering RAG on ...") are available at llmware on Huggingface. Explore using the model repository and the llmware Huggingface integration in llmware examples.

🔹 Alternate options for running MongoDB and Milvus

There are several options for getting MongoDB running

🐳 A. Run mongo container with docker

docker run -d -p 27017:27017  -v mongodb-volume:/data/db --name=mongodb mongo:latest

🐳 B. Run container with docker compose

Create a docker-compose.yaml file with the content:

version: "3"

services:
  mongodb:
    container_name: mongodb
    image: 'mongo:latest'
    volumes:
      - mongodb-volume:/data/db
    ports:
      - '27017:27017'

volumes:
    llmware-mongodb:
      driver: local

and then run:

docker compose up

📖 C. Install MongoDB natively

See the Official MongoDB Installation Guide

🔗 D. Connect to an existing MongoDB deployment

You can connect to an existing MongoDB deployment by setting the connection string to the environment variable, COLLECTION_DB_URI. See the example script, Using Mongo Atlas, for detailed information on how to use Mongo Atlas as the NoSQL and/or Vector Database for llmware.

Additional information on finding and formatting connection strings can be found in the MongoDB Connection Strings Documentation.

✍️ Working with the llmware Github repository

The llmware repo can be pulled locally to get access to all the examples, or to work directly with the latest version of the llmware code.

Pull the repo locally

git clone git@github.com:llmware-ai/llmware.git

or download/extract a zip of the llmware repository

Run llmware natively

Update the local copy of the repository:

git pull

Download the shared llmware native libraries and dependencies by running the load_native_libraries.sh script. This pulls the right wheel for your platform and extracts the llmware native libraries and dependencies into the proper place in the local repository.

./scripts/dev/load_native_libraries.sh

At the top level of the llmware repository run the following command:

pip install .
