It was so much fun to be able to create a simple AI application using OpenAI API and streamlit and even deploy it so that I could actually use it. The progress was fast, so it wasn't boring and it was so fun that I didn't realize how time flew by.ㅎㅎ I also want to learn how to use langchain, RAG, and vectorDB! It was great! I enjoyed it so much. There were some twists and turns because of the versions of the things I was installing, but it was also an opportunity to learn how to solve those problems. Now, I can create my own chatbot with Telegram and KakaoTalk on my own. Thank you!!!
