AI people on X: ideas, agents and working software

A model demo, a working app and a research paper answer different questions. Meet the people behind them, inspect what they made and choose a useful starting material.

Start with a question

A useful first work is a better starting point than a long list of names.

7 reading tasks

Build software with AI

Follow product prototypes, coding-agent workflows and the practices used to inspect and test generated code.

Builders & products

Understand language models

Explore explanations, training systems and reasoning studies, then choose an original paper or implementation.

Foundations & explanations

Delegate a multi-step task

Connect models to tools, preserve execution state and inspect how an agent checks the result.

AI agents & automation

Make an AI application dependable

Work with context and documents, build useful evaluation sets and trace quality, latency and cost.

Applied AI engineering

Run a model on your own hardware

Inspect local runtimes, model adaptation and the memory and performance choices behind inference.

Local models & open projects

Understand attacks and data boundaries

Read incident reports, permission models and experiments that examine model behavior.

AI security & interpretability

Create images and video

Explore original media work, generation code and ways to direct a result across successive revisions.

AI for creative work

Explore a reading list

All AI topics

Meet different approaches to the same subject.

Read a claim more closely

Use the original material and figures to see what a claim actually establishes.

  • Open the original claim

    Open the X post behind a demo or research claim. Keep the author's own words separate from quotes and summaries.

    Tweet ID to date
  • Read a score change carefully

    Recalculate a reported change and compare percentage points with relative change. Then check whether the task, dataset and scoring rule stayed the same.

  • Count a prompt before you send it

    Count the tokens in a prompt in your browser and compare what it costs to send to each model.
