LLMs on your local Computer (Part 2)

Sebastian - Mar 18 - - Dev Community

Large Language Models are a ubiquitous technology that revolutionizes the way we work with computers. LLMs in the size of around 7B provide good capabilities and include up-to-date knowledge. With a combination of a specialized data format and quantization, these models can be executed on modes consumer hardware with a six-core CPU and 16GB RAM.

This blog post continues the investigation of running LLMs locally. As before, you will get a brief description of the tool, then see copy-and-paste ready code snippets for installation, model loading, and starting interference. All tools will be compared at a glance, and I will give a personal recommendation.

The technical context of this article is a computer with a recent Linux or OsX distribution, Python v3.11, and the most recent version of the tools. All instructions should work with newer versions of the tools as well.

This article originally appeared at my blog admantium.com.

Library Overview

This article investigates the following librararies:

The concrete hardware requirements can be modest. The reference computer used for running the tools is from 2019 - a Linux PC with Ubuntu 22.04 and the following hardware specs:

To test the text generation capabilities of these modes, the following prompt will be used:

Lit GPT

CLI API GUI GPU Support NVDIA AMD Included Models
20

This project aims to run LLMs on modest computer hardware, providing efficient quantization methods, and a readable code base to encourage other programs to add their specific use cases. The supported models revolve around LLaMA and its variants, but it also supports Pythia, Gemma and Phi.

A strong requirement for lit GPT is to have a NVDIA GPU and CUDA support activated on the target computer - I could not find an option to run the model on the CPU only. Another limitation as pointed out in this issue on GitHub is that model execution only uses 1 CPU core because its PyTorch code base is not yet optimized for multi-core processors.

Installation & Model Loading

git clone <https://github.com/Lightning-AI/lit-gpt>
cd lit-gpt
pip install -r requirements-all.txt

For each model, the project contains an installation file. This file also mentions the to-be expected GPU RAM requirement. Furthermore, it shows how to use different quantization methods.

Given the 4GB limit of my reference computer, I decided to use the pythia-1b model.

Document Upload

On the left side of the UI, you see the option to upload documents. I tried a TXT and PDF file, both works fine. The vectorization process automatically defines text chunks from the imported source and adds them to its database. Once completed, you need to activate the mode "Query Files" and select which documents should be considered for generating an answer.

In the following example, I created a PDF file from the Wikipedia article list of NASA missions, uploaded this document, and used the same prompt.

Interestingly, the log output shows the essentials of a retrieval augmented generation framework: A special system prompt, and the context which are excerpts from the provided file.

NASA (National Aeronautics and Space Administration) is actively involved in space exploration and has several ongoing and upcoming missions. Here are some of the current and future NASA space exploration missions:
1. Artemis Program: The Artemis program is a series of manned and unmanned missions to the Moon, with the goal of establishing a sustainable presence on the lunar surface. The program aims to land the first woman and the next man on the Moon by 2024 and establish a lunar base that can support long-term scientific research, technology development, and human exploration.
2. Space Launch System (SLS) and Orion: The SLS is a heavy-lift rocket that will be used to launch the Orion spacecraft on its missions to the Moon and beyond. The Orion spacecraft is designed to carry astronauts on long-duration missions, including to the Moon and Mars.
3. Commercial Crew Program: NASA is partnering with private companies, such as Boeing and SpaceX, to launch astronauts to the International Space Station (ISS) on commercial spacecraft. The goal of this program is to reduce dependence on Russian spacecraft for transporting astronauts to the ISS.
4. Space Technology Mission Directorate (STMD): STMD is responsible for developing new technologies that can be used in future NASA missions. Some of the current projects include the development of advanced propulsion systems, materials for spacecraft and habitats, and radiation protection for astronauts.
5. Europa Clipper: This mission will send a spacecraft to explore Jupiter's icy moon Europa, which is believed to have a liquid water ocean beneath its surface. The mission will study the moon's subsurface ocean and search for signs of life.
6. Mars Exploration Program: NASA has several ongoing and future missions to Mars, including the Curiosity and Perseverance rovers, which are exploring the Red Planet's surface and studying its geology and climate. Future missions include the Mars 2024 and Europa Clipper missions mentioned above.
7. Wide Field Infrared Survey Telescope (WFIRST): This mission will study the universe in infrared light, providing insights into the formation of galaxies, stars, and planets. The mission will also study the distribution of dark matter and dark energy in the universe.
8. James Webb Space Telescope: The James Webb Space Telescope is a successor to the Hubble Space Telescope and will be the most powerful telescope ever built. It will study the formation of the first stars and galaxies, the evolution of the universe, and the origins of life on Earth and in the universe.
9. Parker Solar Probe: This mission will explore the Sun's corona, the outer atmosphere of the Sun, and study the solar wind, which affects Earth's climate and space weather. The mission will provide insights into the Sun's dynamics and how it affects the solar system.
10. Roman Space Telescope: This mission will explore the universe in visible light, providing insights into the formation of galaxies, stars, and planets. The mission will also study the distribution of dark matter and dark energy in the universe.
These are just a few examples of the many active space exploration missions conducted by NASA. Each mission is an exciting step towards expanding our understanding of the universe and the mysteries it holds.

Additional Tools

During the research for this article, I encountered additional libraries concerned with LLM hosting. While not fitting the scope of running current LLMs on modest hardware, they are listed here for others who are curious to explore the landscape of libraries.

  • AutoGPTQ: Comprehensive library for LLM quantization using the GPTQ algorithm. Its API extends HuggingFace Transformers for integrated quantization and language tasks like completions, causal generation, and more. NVDIA and AMD GPUs are supported.
  • gptq: A new state of the art quantization method. The project includes scripts to quantize OPT and BLOOM models as well as running language perplexity and zero-shot benchmarks.
  • Intel Extension for Transformers: A serving platform and framework for running LLMs on Intel processors. The repository contains an extensive list of tutorials and examples starting with several quantization and compression techniques, evaluating performance, and building language generators or chatbots with Python. It also integrates with the Transformers and LangChain library.
  • lit-llama: Pretraining, fine-tuning and interference of the LLaMA model. This precursor project to lit-gpt also aims to make LLMs usage accessible to a wide audience.
  • nanoGPT: Fine-tuning Gen1 and Gen2 LLMs like GPT2. It provides comprehensive scripts to load custom fine-tuning datasets and start the training process.
  • Shell GPT: A helper tool included in your terminal shell to generate bash and other scripts. It connects to OpenAI APIs for generating the code. Alternatively, you can run local models with Ollama.
  • vllm: Running LLMs at scale supporting Docker, Kubernetes, and NVIDIA Triton for hosting distributed LLMs over several nodes. Supports native quantization methods, NVIDIA and AMD GPUs, and several Transformers compatible models.
  • whisper.cpp: Speech recognition based on OpenAIs whisper library. Developed by the same person as the ggml library, it shows again how to port a complex technology to several target devices, including computers, mobile phones, and even the browser.

Conclusion

Running large language models on your local computer is a fascinating experience. Through quantization and special file formats, 7B models can be run locally, giving you full command of an LLM as a standalone tool or component for an application. This article explored another 5 libraries: Lit GPT, LocalAI, llamafile, PrivateGPT, LM Studio. They support LLM interactions using CLI, REST API or GUI. An interesting trend is that the GGUF file format becomes dominant, which gives access to a continously growing amount of models.
