summary: '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. I also added an llm anthropic count command which can use their free token counting API to return a count of tokens that will be used by any prompt, before you send that prompt. Tags: llm, anthropic'

[llm-anthropic 0.30](https://github.com/simonw/llm-anthropic/releases/tag/0.30) — LLM access to models by Anthropic, including the Claude series

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.

I also added an `llm anthropic count` command which can use their free token counting API to return a count of tokens that will be used by any prompt, before you send that prompt.
