llm-anthropic 0.30 adds Claude Sonnet 5.5, live model refresh, and free token counting.

Simon Willison released llm-anthropic 0.30, the Anthropic plugin for his llm command-line tool. Besides Claude Sonnet 5.5 support, it adds llm anthropic refresh, which updates the model list directly from Anthropic's API so new models do not require a plugin release. A new llm anthropic count command uses Anthropic's free token-counting API to estimate prompt tokens before sending them.

Key facts
  • Release adds support for Claude Sonnet 5.5.
  • llm anthropic refresh pulls the current model list from Anthropic's API.
  • llm anthropic count uses Anthropic's free token-counting API before a prompt is sent.

From the original article

Release: llm-anthropic 0. 30 In addition to Claude Sonnet 5. 5, this release adds the ability to run llm anthropic refresh to refresh the list of Anthropic models directly from their API - which means I don't need to push a new release just to add support for a newly released model.
