In this video, Prompt Engineering introduces Google’s new Gemini API feature: Code Execution (Interpreter). This feature allows the model to generate and execute Python code on the backend, providing results in real-time. The video demonstrates the power of this feature by comparing it with traditional function calling and showing how it can solve various problems, such as counting occurrences of a letter in a word, sorting lists, and running simulations. The host explains the differences between code execution and function calling, highlighting the simplicity and efficiency of code execution. The video also covers limitations, such as the 30-second execution time limit and the current support for only Python with specific libraries. Several examples are provided, including mathematical calculations, string manipulation, data analysis, web scraping, and training machine learning models. The host concludes by discussing the pricing of the Gemini API and teasing future features like context caching.
