LLMs • **the tech behind GPT** # Large Language Models Understand the AI everyone's talking about — and build with it. Learn how large language models like GPT actually work (tokens, embeddings, attention, transformers), then build real applications using LLM APIs, embeddings and RAG in Python. Live, hands-on, mentor-led. Book a Free DemoSee the Roadmap**GPT**How it works**5–8**Students per batch**RAG**Build real apps**Live**Mentor-led ## Quick answer **Modern Age Coders' Large Language Models Course teaches both how LLMs like GPT work and how to build with them.** You'll understand tokens, embeddings, attention and the transformer architecture, then build real applications using LLM APIs in Python — prompting, embeddings, retrieval-augmented generation (RAG) and an introduction to fine-tuning. Classes are live in small batches of 5–8 with a mentor, group plans start at ₹1,499/month, and a free demo comes first.

The Roadmap ## The LLM Roadmap Four stages from understanding to a working LLM app. STAGE 01 ### Transformers Tokens, embeddings and attention — how LLMs represent and process language. STAGE 02 ### Build with APIs Use LLM APIs in Python to generate, summarise and reason. STAGE 03 ### RAG Add retrieval so the model answers from your own documents. STAGE 04 ### App & Fine-Tune Ship an LLM-powered app and explore fine-tuning. What's Next ## Go Further With LLMs Tracks that pair with LLM skills.

Understanding how they work and how to engineer with them is one of the most valuable skills you can have right now. ### Beyond using ChatGPT Anyone can type into a chatbot. The career skill is building applications — RAG systems, assistants, tools — on top of LLM APIs, and knowing the architecture well enough to make good engineering choices. That's what we teach. ### Part of the generative-AI stack This connects directly to [prompt engineering](/prompt-engineering-course), [AI agents](/ai-agents-course) and [generative AI](/generative-ai-course) — together they're the modern AI-product toolkit.

Understanding transformers made every design choice clearer." Aditya R.Working professional★★★★★ "This took me from 'ChatGPT user' to 'I can build LLM apps'. Huge for my career." Sana M.Career switcher★★★★★ "Clear on attention and embeddings, and the hands-on API work was gold." Vivek K.College student ## Build with the AI everyone's talking about Book a free demo and build an LLM-powered app with a mentor before you spend a rupee. Book a Free Demo Good To Know ## Frequently Asked Questions What does the Large Language Models Course cover?+ It covers How LLMs Work, Build with LLM APIs, RAG & Fine-Tuning. Understand the AI everyone's talking about — and build with it. Learn how large language models like GPT actually work (tokens, embeddings, attention, transformers), then build real applications using LLM APIs, embeddings and RAG in Python. Live, hands-on, mentor-led. Who is this course for?+ It's designed for college students, working professionals and serious teens who want practical, job-ready AI and machine-learning skills. After the free demo we place you at the right level for your background. Do I need prior experience to join?+ No heavy prerequisites — we start from the right point for you and build up. Some Python helps for the more advanced topics, and if you're new we cover what you need. The free demo lets us assess your level first. Will I work on real, hands-on projects?+ Yes. Every topic is hands-on in Python/Colab and you build real, mentor-reviewed work — not just theory — so you finish with practical skill and something to show. How much does the course cost?+ Group classes start at ₹1,499 per month for 2 classes a week. A Mini Batch of 3–4 students is ₹2,499 per month, and 1-on-1 mentoring is ₹4,999 per month. A free demo class is available first. Are the classes live and mentor-led?+ Yes. Classes are live in small batches of 5–8 with a mentor who reviews your work, and every session is recorded so you can revise anytime. It's real-time teaching, not pre-recorded videos. --- *Canonical: https://learn.modernagecoders.com/large-language-models-course*
