AWS Generative AI Learning Plan

AWS's free learning path for engineers building on Bedrock. Covers the AWS-specific patterns (Bedrock, SageMaker, Knowledge Bases for RAG, Bedrock Agents) plus general LLM/RAG concepts. Free, vendor-locked, useful only if your stack is AWS. The AI Practitioner cert ($100) and ML Engineer Associate ($150) build on this learning plan; pair with our /learn/certifications page for the cert side.

Neural Networks: Zero to Hero (Andrej Karpathy)

The single most-recommended free resource in modern AI education. Karpathy builds a working autograd engine, then a character-level language model, then a tokenizer, then a working GPT — all from scratch in PyTorch, explaining every line. The 'Let's build GPT' and 'Let's build the GPT Tokenizer' lectures specifically have become canonical references — every senior AI engineer has watched them. The catch: it's 25 hours of dense math-and-code video. You won't follow if you can't keep up with Python + linear algebra. But if you can, no paid course delivers comparable depth.

Pros & cons

AWS Generative AI Learning Plan
Pros
  • +Free, comprehensive AWS-stack curriculum
  • +Direct prep for AWS AI Practitioner + ML Engineer Associate certs
  • +AWS Bedrock content is the deepest available for that platform
Cons
  • AWS-locked — patterns don't transfer to GCP / Azure
  • Some labs require small AWS spend ($5-20)
  • Tier 3 because we list rather than personally vet every module
Neural Networks: Zero to Hero (Andrej Karpathy)
Pros
  • +By a co-founder of OpenAI — no higher-authority instructor exists
  • +Free, on YouTube, with companion GitHub code
  • +The "Let's build GPT from scratch" lecture is the single most-cited free resource in AI education
Cons
  • 25-hour commitment of dense material — you have to actually do the exercises
  • Pre-reqs are real: comfortable Python + undergrad linear algebra
  • No certificate, no community — pure self-direction

Which course is for whom?

AWS Generative AI Learning Plan
Best for
  • · Engineers at AWS-stack companies
  • · Anyone preparing for AWS AI certs
Not ideal for
  • · Non-AWS teams — wrong vendor focus
Neural Networks: Zero to Hero (Andrej Karpathy)
Best for
  • · Engineers who plan to train, fine-tune, or research LLMs at depth
  • · Anyone tired of "wrapper" courses who wants to understand transformers from first principles
Not ideal for
  • · Casual learners — the dropout rate on the lecture series is high for a reason
  • · Anyone wanting application patterns (LangChain, prompt engineering) — wrong course

Editor's short verdict

Take Neural Networks: Zero to Hero (Andrej Karpathy) first if you're new to the topic; once you have the basics, AWS Generative AI Learning Plan is the natural next step. They're complementary in a learning path, not directly competing.
