A deep understanding of AI large language model mechanisms - Build and train LLM NLP transformers and attention mechanisms (PyTorch). Explore with mechanistic interpretability tools
Description
Deep Understanding of Large Language Models (LLMs): Architecture, Training, and Mechanisms
Description
Large Language Models (LLMs) like ChatGPT, GPT-4, , GPT5, Claude, Gemini, and LLaMA are transforming artificial intelligence, natural language processing (NLP), and machine learning. But most courses only teach you how to use LLMs. This 90+ hour intensive course teaches you how they actually work — and how to dissect them using machine-learning and mechanistic interpretability methods.
This is a deep, end-to-end exploration of transformer architectures, self-attention mechanisms, embeddings layers, training pipelines, and inference strategies — with hands-on Python and PyTorch code at every step.
Whether your goal is to build your own transformer from scratch, fine-tune existing models, or understand the mathematics and engineering behind state-of-the-art generative AI, this course will give you the foundation and tools you need.
What You’ll Learn
The complete architecture of LLMs — tokenization, embeddings, encoders, decoders, attention heads, feedforward networks, and layer normalization
Mathematics of attention mechanisms — dot-product attention, multi-head attention, positional encoding, causal masking, probabilistic token selection
Training LLMs — optimization (Adam, AdamW), loss functions, gradient accumulation, batch processing, learning-rate schedulers, regularization (L1, L2, decorrelation), gradient clipping
Fine-tuning and prompt engineering for downstream NLP tasks, system-tuning
Evaluation metrics — perplexity, accuracy, and benchmark datasets such as MAUVE, HellaSwag, SuperGLUE, and ways to assess bias and fairness
Practical PyTorch implementations of transformers, attention layers, and language model training loops, custom classes, custom loss functions
Inference techniques — greedy decoding, beam search, top-k sampling, temperature scaling
Scaling laws and trade-offs between model size, training data, and performance
Limitations and biases in LLMs — interpretability, ethical considerations, and responsible AI
Decoder-only transformers
Embeddings, including token embeddings and positional embeddings
Sampling techniques — methods for generating new text, including top-p, top-k, multinomial, and greedy

What if you have questions about the material?
This course has a Q&A (question and answer) section where you can post your questions about the course material (about the maths, statistics, coding, or machine learning aspects). I try to answer all questions within a day. You can also see all other questions and answers, which really improves how much you can learn! And you can contribute to the Q&A by posting to ongoing discussions.
By the end of this course, you won’t just know how to work with LLMs — you’ll understand why they work the way they do, and be able to design, train, evaluate, and deploy your own transformer-based language models.
