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.

Microsoft Azure AI Fundamentals (AI-900) prep

The free prep path for AI-900 — Microsoft's foundational AI certification. Covers Azure AI services (Cognitive Services, Azure OpenAI, vision, language) at a vocabulary-building depth. Free to learn; $99 to take the exam. Worth it for non-engineers at Azure shops who need a cert; skippable for engineers who don't care about Azure-specific signal.
