How to Build a Weather Bot with OpenAI function calling Capability | @OpenAI

In this video, I will show you how to use the OpenAI API Function Calling capability to build a weather bot using CHAINLIT UI that can answer questions about the current weather in any location. You will learn how to:

– Recent updates from OpenAI.
– Use the function calling capability of OpenAI’s GPT models to execute external functions from within the text generation process.
– Create a more steerable model with proper system instructions.
– Use RapidAPI to access weather data from various sources and integrate it with OpenAI’s API.
– Create a chat completion function to handle natural language queries and call external functions as needed.
– Generate natural responses from weather data using prompt engineering techniques.
– Build a simple UI for your weather bot using Chainlit.
– You will also get access to the project repo and the OpenAI cookbook that contains practical examples and tips for using OpenAI’s API.

This video is suitable for beginners and intermediate users who want to learn more about OpenAI’s new function-calling capability and how to use it for various applications.
