Ai Engineering From Scratch
Build every AI algorithm from raw math, free & open source — 523 lessons in 4 languages.
If you're a self-starter with strong math and programming chops, this is the most thorough free AI curriculum we've found. It's brutal but rewarding. Skip it if you need hand-holding, videos, or a certificate. Alternatives like Fast.ai or Coursera's Deep Learning Specialization offer guided paths, but nothing matches this depth for zero cost.

About Ai Engineering From Scratch
AI Engineering from Scratch is a free, MIT-licensed curriculum that rebuilds core AI algorithms from first principles. It spans 523 lessons across 20 phases, covering everything from linear algebra to autonomous swarms. Code is written in Python, TypeScript, Rust, and Julia. Maintained by Rohit Ghumare and contributors on GitHub, the site is plain HTML/CSS/JS generated from Markdown — no paywall, no signup, no gated content. This is for engineers who want deep understanding over surface-level fluency. It's the spine most AI tutorials lack: each lesson runs a loop — read the problem, derive the math, write the code, run the test, keep the artifact. No videos, no copy-paste deploys. A companion book edition (six volumes, EPUB and PDF) is built from the same lessons and attached to every GitHub release. The site remains the living edition with animated figures and quizzes. The curriculum now includes a GitHub tutor feature and dedicated paths for Model Context Protocol (MCP) and Agent Skills. You can learn in your terminal via npx skills, and even get certification prep for Claude paths — 33 lessons and 295 practice questions, though not affiliated with Anthropic. Four core learning paths let you choose your focus: Building and Deploying AI Applications, Software Engineering Fundamentals, Agent-Assisted Engineering, and Product Judgment and Delivery. Compared to framework-first courses (e.g., PyTorch from day one), this curriculum forces you to implement backprop, tokenizer, attention, and agent loop manually before using any library. It's rigorous, demanding, and not for everyone — but for those who persevere, it replaces guesswork with genuine competence.
Behind the Verdict
AI Engineering from Scratch stands out in a crowded field of AI tutorials because it refuses to skip the math. Most courses have you import PyTorch on day one and call a model; this one has you implement backprop, tokenizer, attention, and the agent loop yourself, in Python, TypeScript, Rust, or Julia. That's a different kind of learning — slower, harder, but it builds genuine competence. Strengths: The curriculum is exhaustive (523 lessons, 20 phases) and well-structured, with four core learning paths plus focused MCP and Agent Skills paths. The GitHub tutor (via SKILL.md) works with Claude, Cursor, and Codex to give you an interactive, personalized learning experience right in your terminal. The book edition (EPUB/PDF) is a nice complement, and everything is free and open source under MIT — no paywall, no signup. Weaknesses: It's not for everyone. There are no videos, no hand-holding, and no interactive grading. The lessons assume a solid math and programming background, so complete beginners will struggle. There's no formal certification or guaranteed outcome — the Claude certification prep is explicitly not affiliated with Anthropic and doesn't issue credentials. Progress tracking is browser-only, so it resets if you clear your cache. Where it fits: Self-taught engineers, CS students, and professionals transitioning into AI who want to understand what's under the hood. If you're the kind of person who likes to build things from scratch and hates black boxes, this is your resource. Where it doesn't: If you want a guided, video-based course with a certificate, or you need to ship a production AI app fast using frameworks, look elsewhere — Fast.ai and Coursera's Deep Learning Specialization are more approachable.

Featured Head-to-Head Comparisons
Ai Engineering From Scratch vs Surge Ai
If you're an engineer who wants to truly understand AI by building algorithms from scratch, choose Ai Engineering From Scratch — it's free, comprehensive, and MIT-licensed. If you need expert human feedback for RLHF, red teaming, or benchmarking frontier models, Surge AI is the specialized platform, with recent projects like Microsoft using Surge for MAI-Thinking-1 and benchmarks like Riemann-bench exposing model weaknesses. They're complementary: use one to learn, the other to refine production systems.
Ai Engineering From Scratch vs Praktika
These tools serve entirely different needs. Ai Engineering From Scratch is a free, in-depth curriculum for developers who want to master AI from first principles. Praktika is a freemium mobile app for intermediate language learners who want conversational speaking practice. Choose based on your primary goal: technical AI depth or language fluency.
