OpenAI made their GPT-4 API generally available. what are you building with it?

I'm super thrilled to be using GPT-4 API to build an interactive, personalized learning assistant that tailors educational content to individual learning styles, making learning fun, engaging, and more effective for students globally!

Just integrated GPT-4 into my chatbot, making customer support insanely smarter. This thing's a game-changer!
