In this video, you will learn how to invoke code functions in your AI workflows with the Arcee Caller model and the OpenAI API. Caller is optimized for managing complex tool-based interactions and API function calls. Its strength lies in precise execution, intelligent orchestration, and effective communication between systems–making it indispensable for sophisticated automation pipelines.

First, we take a quick look at Caller in the Model Engine UI. Then, we run a notebook combining Caller and the Yahoo Finance API to answer company-related questions. Finally, we see how we can use other models like Virtuoso to process and improve the output of the function calls.
