Training a large language model is like teaching someone how to speak and behave.
The process of training can be broken down into three stages: self-supervised pre-training, supervised fine-tuning, and reinforcement learning from human feedback.
In the pre-training stage, the model learns by reading a large amount of text and predicting the next word in a sentence.
In the fine-tuning stage, the model is guided to mimic correct answers and examples, similar to a child being taught proper behavior.
