Use The llm CLI With Claude Models

Simon Willison's llm can be used with a bunch of different models (local and API). The whole thing is plugin driven. To use a specific model, you'll need to install the plugin for it. For instance, to use the Claude 3 family of models you need to install llm-claude-3.

$ llm install llm-claude-3

Then when prompting llm, specify which of the Claude models you want to use — claude-3-haiku, claude-3-sonnet, or claude-3-opus — with the -m flag:

$ llm \
  -m claude-3-haiku \
   --key $CLAUDE_API_KEY \
  'Show me the SQL query to create a cocktails table.'

Note: instead of adding my Claude API key to the key store, I've opted to include it with the --key flag via an environment variable that I've set ahead of time.
