A harness plugin that autoswitches to the appropriate model to save u tokens (github.com)

A new plugin called "autoswitch" has been introduced for Claude Code, designed to automatically select the most suitable AI model for different prompts, eliminating the need for manual model switches. This tool is particularly useful as users often forget to switch from high-capacity models like Opus 5.5 to more appropriate options such as Sonnet for simpler tasks. The plugin requires Claude Code version 2.1.299 or higher, along with an Anthropic API login, and utilizes a ranking system to match the right model to a user’s needs while offering the ability to compact conversations and retry with lower-tier models if necessary. The significance of this innovation lies in its potential to optimize resource usage and reduce costs for AI applications. By automating model selection based on the prompt's complexity and required output quality, users can save on token usage while enhancing efficiency. This feature not only streamlines workflows but also democratizes access to resources by allowing models to adapt to user demands without additional overhead. The method ranks models by their capabilities, ensuring users leverage the best available technology for each task while maintaining budget efficiency.
