LLMs, or Large Language Models, are basically artificial intelligence supercomputers that understand and generate text in natural language, like ChatGPT, which has become very popular in the last year.
In this post, we will better understand how this technology works, its advantages and disadvantages, the main models on the market today and how they can be used in creating online courses.
What are Large Language Models (LLMs) and how do they work?
In simpler terms, an LLM is a computer program trained to recognize and interpret human language and other complex data types.
So you may be wondering, but how are these programs trained? Simple, they are “fed” with an immense amount of data collected from across the internet and beyond, with the aim of learning how to answer questions, create content, chat and much more.
LLMs use a type of machine learning called deep learning to understand how characters, words and sentences work together. To get a better understanding of how this all works within the world of AI, see the diagram below.
They are then trained and then go through an adjustment phase, which works as follows:
Training
- The model is trained with huge volumes of text (books, articles, web pages).
- It learns general language patterns such as grammar, logic, and even facts about the world.
- Common tasks include predicting the next word (causal language modeling) or filling in gaps (masked language modeling)
Adjustment
After training, the model is fine-tuned for focused tasks with more specific datasets.
This may include alignment with human preferences or application in specific areas, such as mathematics or customer service, for example.
To be fine-tuning is done through prompts (commands) for a specific task that the user wants the model to do, such as interpreting questions and generating answers or translating text from one language to another.

Advantages and Limitations of LLMs
This technology is, without a doubt, extraordinary, bringing great ease and agility to the most diverse tasks.
However, one of its biggest challenges lies in the fact that the quality of the samples collected affects how well LLMs learn natural language, and the reliability of the data they generate.
This means that although they can perform many tasks, care must be taken when trusting the information generated.
LLMs can indeed provide incorrect or fictitious information, as they depend on the quality and diversity of the training data, and the internet is a sea of data of all types.
Another disadvantage is that, as you can imagine, these programs and require a lot of computation to train and operate, so it will still take time before more “perfect” answers are achieved, although there are already several models available online, such as the following, which we will explore in more depth throughout the article:
- GPT-4: One of the most advanced, widely used for general language assistance.
- PaLM 2: Excellent at multilingual and creative tasks.
- LLaMA: Focused on research and efficiency.
- Claude: Optimized for safe and ethical responses.
How to use LLMs?
As we mentioned, LLMs can be used in the most diverse tasks and areas of activity, facilitating and optimizing these activities.
Some possibilities include:
- Business and Customer Service: Response automation, intelligent chatbots, technical support.
- Education: Virtual tutors, personalized explanations, creation of teaching materials.
- Technology and Programming: Helps with code development, debugging and documentation.
- Health: Medical assistance, symptom analysis, organization of medical information.
- Academic Research: Summaries, bibliographic reviews, generation of hypotheses.
- Creativity and Content: Creative writing, idea generation, script development.
- Marketing: Campaign creation, trend analysis, message personalization.

How to Use LLMs in Online Courses
Although many people can only see LLMs as tools for generating text, they can go much further than that.
When creating online courses, you can bring more interactivity and personalization to learning.
Imagine a course where each student has an intelligent virtual assistant at their disposal, capable of answering questions, explaining concepts in different ways or adapting the content according to their individual pace and needs.
In courses with complex modules, such as programming or mathematics, the LLM can offer detailed or simplified explanations depending on the student’s previous experience.
It can also help in practice, correcting exercises and providing instant feedback, which reduces the need to wait for an instructor to return.
Furthermore, the model can suggest complementary materials, such as articles, videos or personalized exercises, to reinforce points where the student has difficulty.
Another application is in content creation. Instructors can use LLMs to generate study materials such as summaries, quizzes and multiple choice questions, saving time and ensuring content is up to date and relevant.
This is especially useful in courses that need to be updated frequently, such as technology, nutrition, or digital marketing.
Are you already impressed? Well, know that both your online course and your advertising can get even better!
LLMs can be integrated into course discussion forums or chats, functioning as moderators who answer frequently asked questions or help mediate discussions between students.
Finally, the models can be used in assessments, making automated corrections to tests (including essays) or giving feedback on written work, highlighting strengths and areas for improvement.
All of this contributes to a richer learning experience, accessible and adapted to each student.
To make everything clearer, let’s look at a practical example, which would be the use of LLMs in a language course.

How to use LLMs in an online language course?
With advanced text comprehension and generation capabilities, LLMs can be integrated to act as tutors, conversational partners, and creative assistants, meeting the needs of learners at different levels.
Imagine the model as a practice partner, available 24 hours a day.
It can simulate dialogues with students, adjusting vocabulary and sentence complexity based on each student’s proficiency level.
In addition to helping you practice writing and speaking, it has the ability to correct errors immediately, explaining the correction and even suggesting alternatives. This turns the practice into a continuous learning process.
In writing, LLMs are equally useful. They can grade essays or open-ended responses, providing detailed feedback on grammar, vocabulary, style, and coherence.
The student can also ask for help to expand their vocabulary, requesting synonyms, idiomatic expressions or examples of contextual use.
Another powerful application is in content personalization. LLM can create specific exercises for each student based on their difficulties, such as verb conjugation, translation or reading comprehension practices.
He can also generate quizzes, interactive games or challenges that keep students engaged and motivated.
Finally, LLM can be used to provide cultural context, explaining slang and expressions, or differences between regional variants of a language.
This helps the student not only learn the language, but also understand its practical and cultural use.
If integrated strategically, LLM can bring enormous benefits for both students and instructors.
