Scrimba
Scrimba's interactive career path for building AI-powered apps in JavaScript, covering LLM APIs, embeddings and RAG, and agents, with code you edit directly inside the screencasts. It suits web developers who want a guided, hands-on route into AI engineering at a low monthly cost rather than assembling free resources themselves.
Developers and technically curious learners. This is a beginner-level course in Generative AI & LLMs, running about ~11.4 hours.
$24.50/mo. Requires Scrimba Pro, about $24.50 per month billed annually per Scrimba's own course roundup. Price seen 2026-11-01.
Google Cloud's short beginner path explaining what generative AI and large language models are, how they work, and the principles of responsible AI. A fast, free badge-earning starting point for non-technical professionals before moving to Google's deeper developer paths.
Microsoft's 21-lesson course on building generative AI apps, with Learn and Build lessons covering prompting, RAG, embeddings, function calling, agents, fine-tuning, and security in Python and TypeScript. Great for developers who want a free, code-first path from LLM basics to deployable applications.
A large catalogue of runnable notebooks, each isolating one retrieval-augmented generation technique, from basic chunking and query transformations to reranking, hierarchical and graph-based retrieval, and evaluation. It suits developers who have built a basic RAG app and want to systematically try the techniques that improve retrieval quality.
