Google Cloud Generative AI Learning Path

Google's free GenAI learning path on Cloud Skills Boost. 10 courses covering generative AI fundamentals, Vertex AI, Gemini API, prompt engineering on Google's stack, and responsible AI. Free, vendor-locked to GCP. The right learning path if your company runs on GCP / Vertex AI; otherwise the AWS or Microsoft equivalents are similar quality.

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

Google Cloud Generative AI Learning Path
Pros
  • +Free, comprehensive 10-course path
  • +Direct prep for Generative AI Leader cert
  • +Best Gemini API coverage available
Cons
  • −GCP-locked — patterns don't transfer cleanly to AWS / Azure
  • −Lab credits cost a few dollars if you exhaust the free tier
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?

Google Cloud Generative AI Learning Path
Best for
  • · Engineers and PMs at GCP-stack companies
  • · Anyone building with the Gemini API
Not ideal for
  • · Non-GCP teams
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 Google Cloud Generative AI Learning Path first if you're new to the topic; once you have the basics, Neural Networks: Zero to Hero (Andrej Karpathy) is the natural next step. They're complementary in a learning path, not directly competing.
