Description
Large Language Models (LLMs) are redefining what's possible with AI — from chatbots to code generation — but the barrier to training and deploying them is still high. Expensive hardware, massive memory requirements, and complex toolchains often block individual practitioners and small teams. This course is built to change that.

In thishands-on, code-first training, you’ll learn how to fine-tune models likeMixtral-8x7BusingQLoRA— a state-of-the-art method that enables efficient training by combining4-bit quantization,LoRA adapters, anddouble quantization. You’ll also gain a deep understanding ofquantized arithmetic,floating-point formats (like bfloat16 and INT8), and how they impact model size, memory bandwidth, and matrix multiplication operations.

You’ll write advanced Python code topreprocess datasets with custom token-aware chunking strategies, dynamically identify quantizable layers, and inject adapter modules using thePEFT (Parameter-Efficient Fine-Tuning)library. You’ll configure and launchdistributed fine-tuning jobs on AWS SageMaker, leveraging powerful multi-GPU instances and optimizing them usinggradient checkpointing,mixed-precision training, andbitsandbytes quantization.

After training, you’ll go all the way to deployment:merging adapter weights, saving your model for inference, and deploying it viaSageMaker Endpoints. You’ll then expose your model through anAWS Lambda functionand anAPI Gateway, and finally, build aStreamlit applicationto create a clean, responsive frontend interface.

Whether you’re a machine learning engineer, backend developer, or AI practitioner aiming to level up — this course will teach you how to move from academic toy models toreal-world, scalable, production-ready LLMsusing tools that today’s top companies rely on.

Who this course is for:
- Machine Learning Engineers
- Backend and MLOps Engineers
- AI Researchers and Students
- Anyone who wants to go beyond "prompt engineering" and start building, training, and deploying their own production-ready LLMs.
