Research in artificial intelligence is increasing at an exponential rate. It’s difficult for AI experts to keep up with everything new being published, and even harder for beginners to know where to start.

So, in this post, we’re sharing a curated list of resources we’ve relied on to get smarter about modern AI. We call it the “AI Canon” because these papers, blog posts, courses, and guides have had an outsized impact on the field over the past several years.

We start with a gentle introduction to transformer and latent diffusion models, which are fueling the current AI wave. Next, we go deep on technical learning resources; practical guides to building with large language models (LLMs); and analysis of the AI market. Finally, we include a reference list of landmark research results, starting with “Attention is All You Need”—the 2017 paper by Google that introduced the world to transformer models and ushered in the age of generative AI.

A gentle introduction…

These articles require no specialized background and can help you get up to speed quickly on the most important parts of the modern AI wave.

  • Software 2.0: Andrej Karpathy was one of the first to clearly explain (in 2017!) why the new AI wave really matters. His argument is that AI is a new and powerful way to program computers. As LLMs have improved rapidly, this thesis has proven prescient, and it gives a good mental model for how the AI market may progress.
  • State of GPT: Also from Karpathy, this is a very approachable explanation of how ChatGPT / GPT models in general work, how to use them, and what directions R&D may take.
  • What is ChatGPT doing … and why does it work?: Computer scientist and entrepreneur Stephen Wolfram gives a long but highly readable explanation, from first principles, of how modern AI models work. He follows the timeline from early neural nets to today’s LLMs and ChatGPT.
  • Transformers, explained: This post by Dale Markowitz is a shorter, more direct answer to the question “what is an LLM, and how does it work?” This is a great way to ease into the topic and develop intuition for the technology. It was written about GPT-3 but still applies to newer models.
  • How Stable Diffusion works: This is the computer vision analogue to the last post. Chris McCormick gives a layperson’s explanation of how Stable Diffusion works and develops intuition around text-to-image models generally. For an even gentler introduction, check out this comic from r/StableDiffusion.

Foundational learning: neural networks, backpropagation, and embeddings

These resources provide a base understanding of fundamental ideas in machine learning and AI, from the basics of deep learning to university-level courses from AI experts.

Explainers

Courses

  • Stanford CS229: Introduction to Machine Learning with Andrew Ng, covering the fundamentals of machine learning.
  • Stanford CS224N: NLP with Deep Learning with Chris Manning, covering NLP basics through the first generation of LLMs.

Tech deep dive: understanding transformers and large models

There are countless resources—some better than others—attempting to explain how LLMs work. Here are some of our favorites, targeting a wide range of readers/viewers.

Explainers

Courses

  • Stanford CS25: Transformers United, an online seminar on Transformers.
  • Stanford CS324: Large Language Models with Percy Liang, Tatsu Hashimoto, and Chris Re, covering a wide range of technical and non-technical aspects of LLMs.

Reference and commentary

  • Predictive learning, NIPS 2016: In this early talk, Yann LeCun makes a strong case for unsupervised learning as a critical element of AI model architectures at scale. Skip to 19:20 for the famous cake analogy, which is still one of the best mental models for modern AI.
  • AI for full-self driving at Tesla: Another classic Karpathy talk, this time covering the Tesla data collection engine. Starting at 8:35 is one of the great all-time AI rants, explaining why long-tailed problems (in this case stop sign detection) are so hard.
  • The scaling hypothesis: One of the most surprising aspects of LLMs is that scaling—adding more data and compute—just keeps increasing accuracy. GPT-3 was the first model to demonstrate this clearly, and Gwern’s post does a great job explaining the intuition behind it.
  • Chinchilla’s wild implications: Nominally an explainer of the important Chinchilla paper (see below), this post gets to the heart of the big question in LLM scaling: are we running out of data? This builds on the post above and gives a refreshed view on scaling laws.
  • A survey of large language models: Comprehensive breakdown of current LLMs, including development timeline, size, training strategies, training data, hardware, and more.
  • Sparks of artificial general intelligence: Early experiments with GPT-4: Early analysis from Microsoft Research on the capabilities of GPT-4, the current most advanced LLM, relative to human intelligence.
  • The AI revolution: How Auto-GPT unleashes a new era of automation and creativity: An introduction to Auto-GPT and AI agents in general. This technology is very early but important to understand—it uses internet access and self-generated sub-tasks in order to solve specific, complex problems or goals.
  • The Waluigi Effect: Nominally an explanation of the “Waluigi effect” (i.e., why “alter egos” emerge in LLM behavior), but interesting mostly for its deep dive on the theory of LLM prompting.

Practical guides to building with LLMs

A new application stack is emerging with LLMs at the core. While there isn’t a lot of formal education available on this topic yet, we pulled out some of the most useful resources we’ve found.

Reference

  • Build a GitHub support bot with GPT3, LangChain, and Python: One of the earliest public explanations of the modern LLM app stack. Some of the advice in here is dated, but in many ways it kicked off widespread adoption and experimentation of new AI apps.
  • Building LLM applications for production: Chip Huyen discusses many of the key challenges in building LLM apps, how to address them, and what types of use cases make the most sense.
  • Prompt Engineering Guide: For anyone writing LLM prompts—including app devs—this is the most comprehensive guide, with specific examples for a handful of popular models. For a lighter, more conversational treatment, try Brex’s prompt engineering guide.
  • Prompt injection: What’s the worst that can happen? Prompt injection is a potentially serious security vulnerability lurking for LLM apps, with no perfect solution yet. Simon Willison gives the definitive description of the problem in this post. Nearly everything Simon writes on AI is outstanding.
  • OpenAI cookbook: For developers, this is the definitive collection of guides and code examples for working with the OpenAI API. It’s updated continually with new code examples.
  • Pinecone learning center: Many LLM apps are based around a vector search paradigm. Pinecone’s learning center—despite being branded vendor content—offers some of the most useful instruction on how to build in this pattern.
  • LangChain docs: As the default orchestration layer for LLM apps, LangChain connects to just about all other pieces of the stack. So their docs are a real reference for the full stack and how the pieces fit together.

Courses

  • LLM Bootcamp: A practical course for building LLM-based applications with Charles Frye, Sergey Karayev, and Josh Tobin.
  • Hugging Face Transformers: Guide to using open-source LLMs in the Hugging Face transformers library.

LLM benchmarks

  • Chatbot Arena: An Elo-style ranking system of popular LLMs, led by a team at UC Berkeley. Users can also participate by comparing models head to head.
  • Open LLM Leaderboard: A ranking by Hugging Face, comparing open source LLMs across a collection of standard benchmarks and tasks.

Market analysis

We’ve all marveled at what generative AI can produce, but there are still a lot of questions about what it all means. Which products and companies will survive and thrive? What happens to artists? How should companies use it? How will it affect literally jobs and society at large? Here are some attempts at answering these questions.
