Self-host Llama3 for Bytebase AI Assistant

For data security reasons, you may want to enable AI Assistant with a self-deployed LLM. Here we chose the powerful open source model Llama3. We used Ollama and One API as a relay to convert between Bytebase’s OpenAI API-compliant requests and Llama3 API requests.

​

Prerequisites

Before you begin, make sure you have:

• Docker installed
• Bytebase instance running

​

Get Llama3 running in Docker

Run the following command in terminal to get a Docker container running:

docker run -d -p 11434:11434 --name ollama --restart always ollama/ollama

Container starts and returns id, then enter the container with the following command:

docker exec -it ollama bash

Pull and run the Llama3 model. Due to mapping issues, the model needs to be renamed to gpt-3.5-turbo (or mapped in One-API). After renaming, the model name is gpt-3.5-turbo, but indeed it is still Llama3.

ollama pull Llama3
ollama cp Llama3 gpt-3.5-turbo
ollama run gpt-3.5-turbo

Now that the model is running, you can test if the API is working properly in a new terminal page:

curl http://localhost:11434/api/generate -d '{
  "model": "gpt-3.5-turbo",
  "prompt":"Why is the sky blue?"
}'

Seeing the results streaming out means that API is working well.

​

Configure One API

Choose a directory with read&write permissions (replace YOUR_PATH in the following command) to save data and logs. For example, you can use the pwd command in the mac terminal to view the current path and replace YOUR_PATH with it.

docker run --name one-api -d --restart always -p 3000:3000 -e TZ=Asia/Shanghai -v YOUR_PATH/one-api:/data justsong/one-api-en

Seeing the Docker container start and id output means successful deployment. If you encounter any issues, refer to the solution in One API documentation.

In Docker dashboard, you can see one-api container and its address as well. You can access localhost:3000 here to log in to One API dashboard.

​

Configure Channel

Enter channel page, select Add a new channel. Fill in model information:

• Type: ollama
• Name: Llama3
• Group: default
• Model: gpt-3.5-turbo
• Key: Anything (for example SSSS|sssss|1111) with format APPID|APISecret|APIKey if ollama has not set up for key
• Proxy: the IP address of the ollama container http://host.docker.internal:11434

Furthermore, we mentioned above that the model name can be mapped in One-API. This can be done in the Model redirection bar on this page using a JSON string.

​

Configure API Keys

In the API keys page, click Add New Token, and fill in the Name (for example Llama3) and Model scope (for example gpt-3.5-turbo).

After clicking Submit, you will see the new API key in My keys list within API keys page. Click Copy to get a token starting with sk-, with witch you can repalce YOUR_TOKEN in the code below. If the code runs successfully in your terminal, it means that One API configuration is complete.

curl http://localhost:3000/v1/chat/completions \
    -H "Content-Type: application/json" \
        -H "Authorization: Bearer YOUR_TOKEN" \
    -d '{
        "model": "gpt-3.5-turbo",
        "messages": [
            {
                "role": "user",
                "content": "Tell me a joke."
            }
        ],
        "temperature": 0.7
    }'

​

Configure Bytebase and run

In Bytebase Workspace, go to Settings -> General, and scroll down to AI Assistant section. Fill YOUR_TOKEN we generated in One API into OpenAI API Key bar, and fill the OpenAI API Endpoint bar with http://localhost:3000. Click Update.

Enter SQL Editor from top of any page. You can see an OpenAI icon on top right corner. Click it to start conversation with AI assistant, ask questions in natural language and get SQL results.
