The award for best book box goes to @philipkiely. Loving this book so far! Seriously: a super thoughtful book, branded kitchen tiles, branded bookmark, and what I’m assuming is his favorite tea. Wow.

@modal Hi! I'm planning on hosting a free full-day workshop in SF building an LLM from scratch. Would love to recommend attendees use Modal for long-running notebooks. Is that something you're able to support with free credits? Is there an email I can reach out to?

@philipkiely I wants it. I needs it. After all, why shouldn’t we have it? It’s ours, our precious. But seriously, is there a paperback edition I can just buy?

I made a mistake yesterday and now I have a (good) problem. Turns out I massively underestimated demand for Inference Engineering. Yesterday we saw: > 2M+ views, trending on tech twitter > Shipped books to awesome people worldwide > Thousands more asking for the book The problem? I'm sold out. Was on the phone with my printer in Belgium first thing this morning, more copies on the way by air freight. In the meantime, the PDF on the website is free.

100%. A decade ago you’d need to pay a processional $$$$ and wait two weeks. Five years ago it’d be $$$ to squarespace with lots of fiddling. Today it’s same-day free with any chatbot subscription. (Or pay lovable $300) Wild seeing someone without tech skills to $$$$ deliverable in a day.

@JustinAngel Crazy how fast things move now—AI can take someone from zero to a live website in a single day. 🚀

😲 Wild times with Claude code. My partner, who's never written code before, used claude code yesterday to setup her own website. 9am she learned about claude code and what's a terminal window. 5pm the website was deployed to a domain with a working "contact us" form.

8/ Bonus: and there was lots of enjoyment in this process… The structure provided by the programs with their clear-cut expectations led to satisfaction and up-leveled my skills. I remember happily wandering the green fields of the Capodimonte in Napoli eating a pizza while listening to audio lectures on American history thinking “it doesn’t get better than this”.

How I got my Bachelor’s and Master’s in AI in 5 months and $10k. 🧵 Twenty years ago I dropped out of college. In 2025, I enrolled and completed undergrad and graduate degrees in CompSci AI/ML. Since I’m established in my career (e.g., L8/principal engineer in FANG), my focus was to enjoy grokking AI/ML.
