API keys

To use AI/LLMs with hai, you'll need to authenticate with AI providers in one of two ways:

Use your own API keys

Set an API key for each provider (openai, anthropic, google, deepseek, xai) you intend to use. Choose any of the following methods:

• CLI command:

  $ hai set-key <provider> <key>
  

• REPL command:

  /set-key <provider> <key>
  

• Environment variable:

  $ <PROVIDER>_API_KEY=<key> hai
  

• Config file: Add your keys to ~/.hai/hai.toml

  [openai]
  api_key = "<key>"
  
  [anthropic]
  api_key = "<key>"
  
  [google]
  api_key = "<key>"
  
  [deepseek]
  api_key = "<key>"
  
  [xai]
  api_key = "<key>"
  

Use hai router

hai router is a subscription service that gives you access to all supported AI providers without using your own keys.

• See subscription details and subscribe:

  /account-subscribe
  

• Enable via REPL:

  /hai-router on
  

• Works on every machine once you login:

  /account-login
  

hai router is an easy way to support the hai project and its ongoing development.
