Proven open source AI technology and tools in 2023

Most companies aren’t fighting for billions of dollars in GPUs or trying to build the next ChatGPT, they’re working to optimize AI for their business. That means using lots of the same tools and approaches for systems integration and making big technology choices between open source AI tools and closed source options.

With the right ecosystem of open source technologies, you can build AI capabilities that cost less to run, are highly customizable, and integrate with your existing open source technology stacks.

High-level benefits of open source AI tools

  • Similar features as closed source AI models (GPT-4)  without extreme costs for training or compute resources.
  • Integration with your existing open source technology – e.g. Kubernetes and Docker.
  • Customization for AI enterprise systems integration that’s not available out of the box.

We’ve been busy building AI applications for our partners in 2023. Here are some of the best open source AI tools and tech you can use to deliver your own enterprise AI capabilities.

Open source AI Large Language Models (LLMs)

LLMs are the driving force in consumer-facing AI technology. There are open source options from companies like Meta and Google that you can use to build your own enterprise chatbots and secure productivity tools.

  • Llama 2 – Llama 2 is an open-source LLM developed by Meta. It’s available for free for research and commercial use. Llama 2 comes in various sizes: 7B, 13B, and 70B parameters. Llama 2 has a context length of 4096 tokens and is available through Azure, AWS, Hugging Face, and other platforms.

    It has a context window size of 2048 tokens, and there are plans to extend it to 10k. Falcon is available on Azure and ranks as the highest-performing pre-trained LLM on the Hugging Face Open LLM Leaderboard.

  • PaLM 2 – PaLM 2 is a transformer-based model released by Google with multilingual, reasoning, and coding capabilities. Google will make PaLM 2 available in four sizes from smallest to largest: Gecko, Otter, Bison, and Unicorn2. It has a context size of 32,000 tokens and is available through Google’s PaLM API. 

  • Yi-34B – A new multilingual model trained by 01.AI and backed by Hai-Fu Lee (Chinese computer scientist and AI investor). Yi-34B is significantly smaller than other open source models in terms of parameter size, but currently outperforms Llama 2-70B and Falcon 180B in certain tasks on the Hugging Face leaderboard.

Open source AI coding models

While there are closed source coding models like ChatGPT and Github Copilot, Meta has designed an open source one just for writing code. It even has a specialized version for Python, which is a critical open source language for AI applications. 

  • Code Llama – In benchmark testing, Code Llama outperformed other state-of-the-art publicly available LLMs on code tasks. It can make software development workflows faster and more efficient and lower the barrier to entry for people learning to code.

    Code Llama is available in three models:

    Code Llama: the foundational code model
    Code Llama Python: specialized for Python
    Code Llama Instruct: fine-tuned for understanding natural language instructions (e.g., code me a website in HTML with these features) 

Open source AI vision models

ChatGPT gets vision features from OpenAI’s GPT-4V model, a powerful vision model, but there’s at least one open source vision model that rivals it – LlaVA. 

You can also pair LlaVA with an open source vision library that’s widely used for computer vision tasks to add well-developed AI capabilities quickly.

  • LlaVA 1.5 – Think GPT-4 vision but open-source. LLaVA represents a novel end-to-end trained large multimodal model that combines a vision encoder and Vicuna for general-purpose visual and language understanding. It achieves similar and impressive chat capabilities that mimic the multimodal GPT-4 model from OpenAI.

  • OpenCV – OpenCV (Open Source Computer Vision Library) isn’t a model like LlaVA, but a robust and versatile library tailored for computer vision tasks – including image recognition, 2D or 3D analysis, motion tracking, and facial recognition. Known for real-time computer vision capabilities, it's a favored choice for developers working on real-time vision applications.

Open source AI frameworks and libraries

AI frameworks provide the foundation and tools for developing, training, and deploying AI capabilities. While many are new and developing, some leaders are emerging in developing enterprise AI applications.

LLM frameworks

  • LlamaIndex – LlamaIndex is a simple, flexible data framework connecting custom data sources to large language models (LLMs).

  • Langchain – LangChain is a framework designed to simplify the creation of applications using large language models. As a language model integration framework, LangChain's use-cases largely overlap with language models in general – including document analysis and summarization, chatbots, and code analysis.

Deep learning frameworks and libraries

  • TensorFlow – Extensive library for high-performance numerical computations.

  • PyTorch – Created by Facebook's AI Research lab, it’s known for dynamic computation graphing – making it particularly suitable for research.
