What interested me in doing this...
I was really interested in AI, which is literally the most important tool to enhance everyone's life and solve real-time problems that require significant human resources. By replacing them with AI, we can address all these issues.
I became interested in building projects around the APIs of models, GPTs, and OSS models. When I was a beginner, it seemed really cool to generate new content from foundational models. However, when I asked real-time questions or something outside the model's training data, I often received default answers like, "I'm only trained on data up to 2022." 
This made me question: what are the ways I can train the foundational model on real-time data and make it available for users? This curiosity led me to delve into fine-tuning, which involves training the foundational model on your private data.
