llm-anthropic 0.26 – support for Claude 5 models and server-side tools
Simon Willison has released version 0.26 of llm-anthropic, a tool for accessing Anthropic models. The update introduces new models (Claude Fable 5, Claude Sonnet 5, Claude Opus 5) and adds server-side tools for web search, webhook fetching, code execution, and Anthropic MCP, along with improved streaming of reasoning events.
WHY IT MATTERS
The update makes it easier to use Anthropic models programmatically and provides access to newer model variants with expanded thinking capacity, which is relevant for developers building applications with Claude.
