Before using openAI for the first time, it seems really helpful to watch it all the way through. There was an AI hackathon within the company, and the parts that were figured out through researching all night and making countless calls were well organized, so I wish I had watched it before. I really regret it. The tuition fee is worth it :) However, the lecturer seemed to have lived abroad for a long time in the English presentation for the concept explanation, so I think he couldn't explain it in Korean so that I could understand it right away. If you read it carefully separately, you can understand it, but it would be really great if you could reinforce that part. Thank you :)
