llm-anthropic 0.28

This article announces the release of llm-anthropic version 0.28, a tool for accessing Anthropic's Claude models via the LLM command-line interface. Key updates include support for the Claude Fable 5.1 model, display of reasoning traces by default for compatible models, and a new exception type (llm_anthropic.ClaudeRefusal) to handle cases where Claude refuses a request. The post is part of Simon Willison's blog and includes tags for LLM, Anthropic, and Claude.
