ChatGPT was launched by OpenAI in November 2022. Since then, it has been the subject of many discussions. ChatGPT itself is one application that was built on top of OpenAI’s GPT-3 models. We can programmatically interact with these models via OpenAI API. In this talk, we will go beyond ChatGPT and discuss OpenAI API, fine-tuning our own models for specific tasks, and building security applications on top of them. We will be building a sample application that interprets human requests and performs the basic tasks requested.
