# Lecture 02. Fundamentals of LLM and Understanding LLM-based Service Planning
## Notice Regarding New Lesson Postings
Hello, students! A total of **388** new lessons (across 43 sections) are scheduled to be posted sequentially for this course. As I am producing multiple courses simultaneously, I am proceeding by **alternating between several courses and posting a little at a time**, rather than uploading one entire course at once. Below are the posting principles and the posting schedule for each section of this course.
> For your reference, the lessons being posted now are not entirely new content, but are part of the process of creating **revised editions (2nd or 3rd editions)** that reinforce existing lectures.
## Posting Principles
- Currently, I am rotating through a total of 19 courses in order (circular method), posting one lesson per course alternately.
- Postings are made on weekdays (MonโFri), with a total of 5 new lessons uploaded across all courses per day.
- For this course, the next lesson will be posted each time its turn in the rotation comes around.
- While the posting speed may feel slow compared to other courses, all courses are progressing together in the same manner.
