Your own ChatGPT for just $0.04/hr – with Ollama, ChatUI and Salad
Deploy your own LLM with Ollama & Huggingface Chat UI on Salad How much does it cost to build and deploy a ChatGPT-like product today? The cost could be anywhere from thousands to millions – depending on the model, infrastructure and use case. Even the same task could cost anywhere from $1000 to $100,000. But with the advancement of open-source models & open infrastructure, there’s been tremendous interest in building a cost-efficient ChatGPT-like tool for various real-life applications. In this article, we explore how tools like Ollama and Huggingface Chat UI can simplify this process, particularly when deployed on Salad’s distributed cloud infrastructure. The challenges in hosting & implementing LLMs In today’s digital ecosystem, Large Language Models (LLMs) have revolutionized various sectors, including technology, healthcare, education, and customer service. Their ability to understand and generate human-like text has made them immensely popular, driving innovations in chatbots, content creation, and more. These models, with their vast knowledge bases and sophisticated algorithms, can converse, comprehend complex topics, write code, and even compose poetry. This makes them highly versatile tools for many enterprise & everyday use-cases. However, hosting and implementing these LLMs poses significant challenges. Despite these challenges, the integration of LLMs into platforms continues to grow, driven by their vast potential and the continuous advancements in the field. As solutions like Hugging Face’s Chat UIand SaladCloud offer more accessible and efficient ways to deploy these models, we’re likely to see an even greater adoption and innovation across industries. What is Ollama? Ollama is a tool that enables the local execution of open-source large language models like Llama 2 and Mistral 7B on various operating systems, including Mac OS, Linux, and soon Windows. It simplifies the process of running LLMs by allowing users to execute models with a simple terminal command or an API call. Ollama optimizes setup and configuration, specifically tailoring GPU usage for efficient performance. It supports a variety of models and variants, all accessible through the Ollama model library, making it a versatile and user-friendly solution for running powerful language models locally. Here is a list of supported models: Model Parameters Size Download Llama2 7B 3.8GB ollama run llama2 Mistral 7B 4.1GB ollama run mistral Dolphin Phi 2.7B 1.6GB ollama run dolphin-phi Phi-2 2.7B 1.7GB ollama run phi Neural Chat 7B 4.1GB ollama run neural-chat Starling 7B 4.1GB ollama run starling-lm Code Llama 7B 3.8GB ollama run codellama Llama 2 Uncensored 7B 3.8GB ollama run llama2-uncensored Llama 2 13B 13B 7.3GB ollama run llama2:13b Llama 2 70B 70B 39GB ollama run llama2:70b Orca Mini 3B 1.9GB ollama run orca-mini Vicuna 7B 3.8GB ollama run vicuna LLaVA 7B 4.5GB ollama run llava What is Huggingface Chat UI? Huggingface Chat UI is a powerful tool for practitioners in the Large Language Model (LLM) space looking to deploy a ChatGPT-like conversational interface. It enables interaction with models hostedon Huggingface, leveraging its text generation inference or any custom API powered by LLM. Chat UI has such capabilities as conversational history, memory, authentication, and theming. Huggingface Chat UI is an ideal choice for those looking to create a more engaging and robust conversational agent. Integrating Ollama and Huggingface Chat UI for deploying on Salad The main goal of our project is to integrate Ollama with Huggingface Chat UI and deploy them to Salad.The final version of the code can be found here: GitHub – SaladTechnologies/ollama-chatui In order to achieve our goal we did the following: 1. Clone Ollama Repository We start by cloning the Ollama repository from Ollama Git Repo. This repository serves as the base of the project.Ollama is a user-friendly tool and can be operated via terminal or as a REST API. In this project, the intention is to run Ollama in a Docker container and connect it to Chat UI. The Dockerfile from Ollama repository shows that it runs on host 0.0.0.0 and port 11434. However, since direct access to Ollama isn’t required but rather through the UI, this configuration will be modified later. 2. Setting Up Huggingface Chat UI Chat UI git repo: GitHub – huggingface/chat-ui: Open source codebase powering the HuggingChat app From the Chat UI Readme, we can see that we need to follow a few steps to make it work in our custom solution: Notice that the path to ollama is specified as http://127.0.0.1:11434. 3. Connecting Ollama and Chat UI We now need to connect Ollama and ChatUI. This involves ensuring that the Chat UI can communicate with the Ollama instance, typically by setting the appropriate port and host settings in the UI configuration to match the Ollama Docker deployment. First we clone the ChatUI repo in our Dockerfile and replace the host that Ollama uses with 127.0.0.1. Next expose port 3000 that is used by ChatUi.We will also replace the entrypoint with our custom shell script: With this script, we establish the necessary .env.local file and populate it with configurations. Next, we initiate the Ollama server in a separate tmux session to download the desired model. ChatUI is then activated on port 3000. For any adjustments in model settings, refer to the models_config/model.local file. We have also converted the MongoDB URL, Huggingface Token, and Model name into environment variables to facilitate seamless alterations during deployment to Salad. Additionally, a DOWNLOAD_TIME variable is defined. Since Ollama runs in a tmux session, it allows subsequent commands to execute even if the server isn’t fully operational. To ensure that Ollama is fully active before initiating ChatUI, we incorporate a sleep duration. This duration is model-dependent; forinstance, downloading llama2 might take around 8 minutes. 4. Deploying to Salad After setting up and connecting Ollama and Chat UI, the complete system is ready for deployment to Salad’s cloud infrastructure. The integrated solution will be hosted on Salad’s robust cloud platform. Detailed deployment instructions and necessary files are accessible through the Salad Technologies Ollama Chat UI GitHub repository or by pulling the image from Salad Docker Registry: saladtechnologies/ollama-chatui-salad:1.0.0. To deploy our solution we need to follow instructions: Deploy a Container Group with
