Installation

npm install -g @callstack/ai-cli

Setup

API key

You will need a valid API key from one of supported AI inference providers: OpenAI or Perplexity. Using these APIs is paid but the costs should be very low, typically much less than $0.01 per interaction.

Quick config

Run ai init to create a basic ~/.airc.json config file with your OpenAI or Perplexity API keys.

$ ai init

Read more about the configuration file format and available option.

Usage

Run ai [query] to start a chat with an AI assistant. You can put the question in the params.

$ ai "Tell me a joke"
me: Tell me a joke
ai: Why don’t skeletons fight each other? They don’t have the guts.

CLI options

CLI options are passed when invoking the ai commend:

• --help: display available options
• --version: display CLI version
• --provider [name] (or -p [name]): select an inference provider to use:
  • openai
  • anthropic (or anth)
  • perplexity (or pplx)
  • mistral
• --model [name] (or -m [name]): select a model to use. This should be a model available for the selected provider.
• --creative: respond in a creative way
• --precise: respond in a more accurate way

You should have a relevant API key in your ~/.airc.json file.
