A new software update for the llm-anthropic plugin has been released, bringing version 0.29 to users. Reported by Simon Willison, the update specifically introduces compatibility for Claude Opus 5.5. Users can now interact with this model directly from the command line interface using the standard syntax. The release centers entirely on integrating the new model option into the existing utility framework.
Command Line Integration for Anthropic Models
The llm utility, created by Simon Willison, serves as a flexible command-line tool designed to interact with various large language models through a unified interface. Plugins like llm-anthropic bridge the core utility with specific model providers. By adding support for Claude Opus 5.5, the 0.29 release allows developers and terminal users to route prompts directly to the specified model using a simple command structure. This approach streamlines testing and automation tasks without requiring custom scripts for each provider’s distinct API.
Unknowns and Future Updates
The announcement did not specify any additional features, bug fixes, or performance improvements included in the 0.29 release beyond the addition of Claude Opus 5.5 support. It remains unclear whether further model variants are scheduled for integration in upcoming versions. Users monitoring the project should watch the repository for subsequent changelogs to see if other provider capabilities are expanded.
Further details regarding the update can be found directly through the project’s official release channels.
