Practical Deep Learning for Coders (fast.ai)

The defining contrarian course in ML education. fast.ai's top-down philosophy — train a working image classifier in lesson 1, understand the math by lesson 6 — works for some learners and frustrates others. We recommend it for engineers who learn by doing rather than by first principles. The course extends to LLMs in later lessons (Jeremy regularly updates), and the companion book ('Deep Learning for Coders with fastai and PyTorch') is genuinely the best paper book on practical deep learning. Free; the only cost is the 70-hour commitment. If Karpathy's Zero-to-Hero is too math-heavy, this is the alternative.

Hugging Face

Hugging Face LLM Course

If you want to fine-tune LLMs in 2026, this is the canonical free resource. Covers transformer architecture, the Hugging Face ecosystem (Transformers, Datasets, Tokenizers), fine-tuning with PEFT/LoRA, RLHF basics, and deployment. Free, regularly updated (the team continually ships new chapters as the field evolves), and the hands-on labs run in free Colab. The course's bias is unavoidably toward open-source models and the HF stack — if you're committing to closed APIs (OpenAI, Anthropic), the abstractions transfer but you'll skip 30% of the content. Worth taking anyway as the broadest free LLM curriculum.

Pros & cons

Practical Deep Learning for Coders (fast.ai)
Pros
  • +Top-down pedagogy — you ship working models from lesson 1
  • +Free, regularly updated, by one of the most respected practitioners in the field
  • +Excellent companion book if you prefer paper
Cons
  • −70 hours is a real ask
  • −Pedagogy is contrarian — some learners want first principles, not top-down
  • −Less LLM-focused than the field demands in 2026; deep-learning generalist
Hugging Face LLM Course
Pros
  • +Free, by the team that built the open-source LLM stack
  • +Continually updated — chapter releases match the field's pace
  • +Hands-on labs run in free Google Colab; no environment setup
Cons
  • −Heavily HF-flavored — if you live on closed APIs, ~30% is less relevant
  • −Heavier prereqs than the DeepLearning.AI shorts (assumes Python + basic ML)

Which course is for whom?

Practical Deep Learning for Coders (fast.ai)
Best for
  • · Engineers who learn by doing, not by deriving
  • · People who tried Karpathy's course and bounced off the math density
Not ideal for
  • · Anyone needing LLM-specific depth — this is broader deep learning
  • · Time-constrained learners — there are shorter paths
Hugging Face LLM Course
Best for
  • · Engineers planning to fine-tune or self-host LLMs
  • · Anyone wanting the broadest free LLM curriculum without paying for Coursera
Not ideal for
  • · People purely consuming closed APIs (OpenAI, Anthropic) — too HF-centric
  • · Complete beginners — pre-req ML knowledge required

Editor's short verdict

Take Hugging Face LLM Course first — it's our Tier-1 pick on this topic and the editorial confidence is higher. Practical Deep Learning for Coders (fast.ai) is a reasonable alternative if you've already taken or evaluated the Tier-1 option.
