A reading list is an argument about what mattered. This one makes a narrow claim: that a dozen-odd papers, read in sequence, are enough to explain how the field traveled from sequence-to-sequence models to systems that will grind on a hard problem for minutes before answering. It is not a canon, not a ranking, and not a syllabus you must finish. It is the shortest path we can defend through a literature that now adds thousands of papers a month.

The arc in four moves

The through-line is easier to hold if you group the work into four shifts, each of which reset what the next generation of researchers took for granted.

Architecture. The transformer replaced recurrence with attention in 2017 and, almost incidentally, handed the field an architecture that scales cleanly across accelerators. Nearly everything after it is a transformer, a lightly modified transformer, or a deliberate reaction to one.

Scale. The 2020 scaling-law paper and GPT-3 turned a qualitative hunch — bigger is better — into smooth, predictable curves, and reframed capability as an engineering variable you buy rather than a trick you stumble onto. DeepMind's Chinchilla then corrected the recipe: most large models of that era were badly undertrained for their size.

Alignment and usefulness. A raw pretrained model predicts text; it does not follow instructions or refuse harm. InstructGPT showed that reinforcement learning from human feedback could bend a base model toward what people actually wanted, and it is the reason the ChatGPT moment felt like a product rather than a demo. Constitutional AI later showed that much of that supervision could come from the model critiquing itself against a written set of principles.

Reasoning. Chain-of-thought prompting noticed that simply asking a model to work step by step unlocked latent capability. OpenAI's o1, in late 2024, turned that observation into a training objective — spend reinforcement learning and inference-time compute on the reasoning itself — and the 2025-2026 wave of reasoning models made deliberate, budgeted thinking a standard axis of the frontier alongside raw scale.

Read in that order, the individual results stop looking like a pile of tricks and start looking like a sequence of moves, each one opening the position for the next.

How to read an ML paper efficiently

You cannot read everything, and you should not read any single paper linearly on the first pass. The durable advice is Srinivasan Keshav's three-pass method: the first pass is title, abstract, figures, and conclusion — enough to decide whether to continue; the second reads the body for the argument while skipping proofs; the third, reserved for papers you need to trust or reproduce, reconstructs the work in your own head.

A few habits separate reading from skimming. Find the central claim and, separately, the evidence offered for it — they are not the same thing, and the gap between them is where most papers are weakest. Go to the ablations before the headline number; they tell you which component actually did the work. Treat a single leaderboard result with suspicion until you know the baseline, the compute budget, and whether the evaluation could have leaked into training. And read the limitations section as if the authors' competitors wrote it — because eventually they will.

Using the list below

The reading list that follows is deliberately short. Each entry carries a one-line note on why it earns its place and links to the paper and, where it exists, the reference code. Read them in order for the narrative above, or treat the list as a map and drop into whichever shift you are missing. If you only have an afternoon, read the transformer, Chinchilla, and InstructGPT; that triangle — architecture, scale, and alignment — is the smallest set that still tells the true story.

One caution worth stating plainly: a road-to-AGI reading list is a claim about direction, and directions are contested. Nothing here proves the current trajectory reaches general intelligence. These are the papers that got the argument to where it now sits — not evidence about where it ends.
