What you'll build

From LLM fundamentals to production-grade AI agents at scale. Master transformer architecture, prompt engineering, RAG pipelines, agent patterns, evaluation, debugging, and deployment — everything a senior AI engineer needs. Every article includes best practices, code examples, and diagrams.

LLM Foundations

Free

19 articles

Everything a software engineer needs to understand about large language models: how transformers work, the model landscape, prompt engineering as a discipline, and when and how to fine-tune.
