DecodeAI helps practitioners build durable ML judgment — not just collect bookmarks. Every offering combines rigorous theory, lesson videos, scored quizzes, cheatsheets, and a verifiable certificate when you complete the work.

Topic courses

Surgical deep dives when you need one skill — optimizers, attention, RAG, MLOps.

Learning tracks

Coherent multi-module paths for foundations in ML, deep learning, and NLP.

Specializations

Career-depth programs in LLM engineering, computer vision, and ML system design.

Meet the team

Built by practitioners, for practitioners

DecodeAI is led by engineers who ship production AI systems — recommendation, retrieval, and LLM infrastructure — and teach the same standards they use at work.

How we teach

Theory → practice → proof

  • Clear mental models first — so equations and code have somewhere to land.
  • Scored quizzes after each topic, with breakdowns you can learn from — not opaque pass/fail.
  • Certificates issued when you pass every topic quiz in a course, with a shareable credential ID.

Freemium by design

Start free. Go deep with Pro.

Free modules let you experience the teaching voice. Pro unlocks the full AI/ML catalog when you are ready to go deeper across tracks and specializations.

Mission

Who DecodeAI is for

Software engineers moving into applied ML, data practitioners sharpening fundamentals, and teams that want a shared curriculum with measurable progress. We optimize for clarity, evaluation discipline, and production-minded tradeoffs — the skills that hold up after the hype cycle moves on.
