The llm-anthropic plugin released version 0.26 with support for three new Claude 5 models (Fable, Sonnet, Opus) and server-side tools including WebSearch, WebFetch, and CodeExecution. The update requires llm>=0.32 and streams reasoning and tool calls as typed events. Reasoning now displays to stderr by default, and extended thinking has been simplified to a thinking parameter with effort levels (low to max), with Claude 5 models using thinking by default.
