Tool choice with Amazon Nova models

Machine Learning Blog



AWS has introduced a new tool choice feature for Amazon Nova models that allows fine-grained control over how tools are used in generative AI applications. This feature enables more precise interaction between language models and external tools or APIs.

  • Three tool choice options are available: Any, Tool, and Auto
  • Allows forcing model to use specific tools or select from available options
  • Supports use cases like structured output generation and API endpoint selection
  • Requires using greedy decoding parameters for best results
  • Helps improve model's ability to interact with external resources and tools

The tool choice feature provides developers more control over how Amazon Nova models interact with external tools, enabling more sophisticated and targeted generative AI applications.
