The AI era has already arrived; it's high time to learn how to integrate it into your applications. In this workshop, we'll learn how to connect Gemini AI to your cross-platform Flutter application using the AI Studio API and Vertex AI API, and even try to run AI models on your device locally. Then, we'll try to connect app to ChatGPT API and compare the capabilities. As a result, we will write an application in which AIs will interact without human assistance and see what comes of it.
