Dive into LLMs is a structured LLM programming tutorial series from Shanghai Jiao Tong University covering fine-tuning, RLHF alignment, RAG pipelines, jailbreak attacks and defenses, watermarking techniques, GUI agents, and multimodal models. Each module includes slides, Jupyter notebooks with runnable code, and accompanying video lectures. The curriculum is designed for developers and researchers who want to go beyond prompt engineering into actually understanding how large language models work, how they're trained, and how to modify and deploy them. Topics span from transformer fundamentals through modern alignment techniques like DPO and GRPO. Recent additions cover GUI agents and multimodal architectures. The course has partnered with Huawei's Ascend community for localized deployment content. With 29k+ GitHub stars and trending hard today, this is one of the most-starred educational resources in the LLM ecosystem. Unlike blog posts and YouTube tutorials, the Jupyter notebooks mean you can run and modify every example yourself — making abstract concepts like RLHF tangible in a way that passive reading can't match.

MacMind is a complete single-layer transformer — attention, positional encoding, backpropagation, and weight updates — implemented entirely in HyperTalk, the scripting language built into Apple HyperCard, running on a Mac SE/30 with an 8 MHz processor and 4 MB of RAM. It trains to learn the bit-reversal permutation fundamental to the Fast Fourier Transform, and in doing so, the attention mechanism independently discovers the Cooley-Tukey butterfly routing pattern — not because it was designed in, but because the gradient descent finds it. Every operation is visible and editable in HyperCard's stack interface. Weights persist between sessions in card fields. The project is a deliberate demonstration that the mathematical operations underlying modern AI — matrix multiplication, softmax, cross-entropy, backprop — are substrate-independent: they work identically on hardware from 1989 as on an H100 cluster today, just much slower. The HN thread was warmly received as a genuine educational artifact: seeing attention, positional encoding, and gradient descent laid bare in HyperTalk's English-like syntax strips away 35 years of abstraction and reveals what transformers actually are. For educators, students, and curious engineers, MacMind is an unusually effective explanation tool.
Reviewer scorecard
“Every dev who uses LLMs in production should understand fine-tuning and alignment at the level this curriculum teaches. The Jupyter notebooks are the key — being able to run RLHF examples on a small model changes your mental model for how alignment actually works.”
“Every engineer who works on LLMs should read this code. HyperTalk's readable syntax forces you to confront what's actually happening in a forward pass — there's no PyTorch autograd magic to hide behind. The fact that attention discovers the FFT butterfly on its own is a genuinely beautiful result worth the price of admission alone.”
“There are dozens of LLM curricula on GitHub — fast.ai, Andrej Karpathy's videos, the Stanford CS224N lectures. Unless you specifically need SJTU's framing or the Huawei Ascend content, it's hard to argue this is uniquely worth your time over the better-known alternatives.”
“This is a teaching toy, not a tool — calling it 'ship' in a practical sense is misleading. The SE/30 trains a trivial task in an hour that PyTorch does in milliseconds. The intellectual point is valid but if you're looking for something to put in a workflow, look elsewhere.”
“The world needs millions more people who understand LLMs at the fine-tuning and alignment level — not just the API level. Open curricula like this are how that happens. The jailbreak and watermarking modules are especially forward-looking for an increasingly adversarial AI landscape.”
“The timing is significant: as AI systems become increasingly opaque and proprietary, projects like MacMind go in the opposite direction — maximally transparent, maximally accessible. Demystification at this level has real cultural value. The next generation of AI researchers may be inspired by seeing a transformer in HyperTalk before they see one in PyTorch.”
“This is squarely for researchers and ML engineers, not creative practitioners. I appreciate the effort but nothing here helps me do my work better today — it's a long-form learning investment that most creators won't need to make.”
“As someone who uses AI tools daily without fully understanding them, MacMind made me genuinely understand what attention is doing for the first time. Clicking through the HyperCard stack and watching weights update in real time is a better explainer than any Medium article. This belongs in every AI literacy curriculum.”
