What you'll learn

  • Fine-tune open-source LLMs for custom business purposes
  • Deploy and scale models for enterprise purposes using AWS SageMaker and Streamlit
  • Understand and implement QLoRA from theory to code
  • Learn to preprocess proprietary datasets with chunking, tokenization, and attention masking
  • Monitor training and performance to ensure optimal business results
  • Manage cloud resources and optimize for cost
  • Apply advanced AI engineering techniques including quantization and more

This isn’t just another “intro to AI” course. It’s a deep dive into the real-world skills that set AI Engineers apart.

You’ll learn how to fine-tune open-source large language models models on custom data, teaching you the skills needed to do the same with a business' proprietary or private data.

Plus you'll conduct fine-tuning using QLoRA - a game-changing technique that drastically cuts resource usage.

But you won’t stop there. Businesses need more from their LLMs. They demand more.

You’ll deploy your own custom LLMs using AWS tools like SageMaker, Lambda, and API Gateway, as well as Streamlit for the creating an easy-to-use user interface for the business' employees or customers.

Along the way, you’ll master concepts like bfloat16 training, dataset chunking, attention masks, HuggingFace’s Estimator API, and much more.

From theory to hands-on coding, this course gives you the full experience of building truly production-ready AI.
