How to Leverage Novita AI with CodeCompanion.nvim

You can find the GitHub repository of CodeCompanion.nvim here: olimorris/codecompanion.nvim.

​
Step 1: Generate Your Novita AI API Key

  1. Log in to your Novita AI account.
  2. Access the Key Management Page.
  3. Create a new API key and copy it for later use.

​
Step 2: Select a Model

  1. Visit the Novita AI Model Library.
  2. Choose a model that suits your needs (e.g., meta-llama/llama-3.1-8b-instruct).
  3. Note down the model name.

​
Step 3: Configure CodeCompanion

We assume you have already installed the Neovim, and if not, you can install it by referring to the Neovim Installation Guide.
  1. Open your Neovim configuration file (init.lua or equivalent).
The Neovim configuration file is typically located at: ~/.config/nvim/init.lua (for macOS or Linux). And you can create this directory and file if they don’t exist yet.
  1. Install the CodeCompanion plugin.
You can install the plugin by referring to the CodeCompanion.nvim Installation Guide.
  1. Add the following setup for CodeCompanion in your Neovim configuration file:
require("codecompanion").setup({
    adapters = {
        novita = {
            base_url = "https://api.novita.ai/v3/openai",
            api_key = "<YOUR_API_KEY>", -- Replace with your actual API key
            model = "meta-llama/llama-3.1-8b-instruct" -- Replace with your chosen model
        }
    }
})
  1. Save and reload Neovim.

​
Step 4: Verify Integration

  1. Run the following command in Neovim:
:checkhealth codecompanion
  1. Ensure all dependencies are installed and configured correctly.

​
Step 5: Test Novita AI Features

  1. Open a code file in Neovim and start using CodeCompanion.nvim features such as inline suggestions or chat-based assistance.
  2. For example:
    • Use shortcuts to trigger intelligent code completions.
    • Start a chat session by invoking :CodeCompanionChat for interactive problem-solving.
