Function calling is a powerful feature of the Claude AI system, allowing it to autonomously take actions and retrieve information to support its language outputs. This is achieved through the use of custom software tools.

These tools enable Claude to break down complex queries into stepwise plans, gathering information, reasoning, and outputting actionable insights. By chaining together multiple API calls, Claude can become a stateful "agent" that can tackle complex tasks with ease.

The process of function calling is further enhanced by "zero-shot" task learning, which allows Claude to learn new tasks and skills simply by being instructed in natural language. This means that users can teach Claude new abilities without needing to provide additional code or training data.

To give you a better idea of how function calling works, here's a list of its key benefits:

Model output evaluations are a crucial part of ensuring the quality and consistency of our chatbot's responses. This process involves scoring and categorizing the chatbot's outputs on various dimensions of quality, consistency, and truthfulness to identify potential error modes and edge cases.

To optimize for key metrics and use cases, we benchmark different prompt variations and model configurations. This allows us to fine-tune the chatbot's performance and ensure it meets the needs of our users.

Tracking and monitoring output quality over time is also essential, as models and prompts evolve. This helps us maintain a consistently high-quality user experience.

By regularly evaluating our chatbot's output, we can identify areas for improvement and make data-driven decisions to enhance its performance.
