Top AI Newsletters of 2025

3 weeks ago | ai-supremacy.com | Ethan Mollick |Sebastian Raschka |Timothy Lee

This list is not exhaustive but features many of the top AI Newsletters on the internet today. 📚 Some of the factors used in the ranking are total paid subscriptions (this is the main criteria) engagement relative to list size⭐ highlighting emerging writers (also check out the “rising” leaderboards in tech in the app)💭 simply my own personal judgment (while browsing Substack’s Tech and Biz leaderboards & analyzing who is reading who that is a huge Venn diagram in and of itself).
Two years of Artificial Ignorance

2 months ago | ignorance.ai | Charlie Guo |Logan Thorneloe |Michael Kevin Spencer |Timothy Lee

This week marks the second anniversary of Artificial Ignorance. 2024 was my first full calendar year of biweekly writing, and it felt like I started to find my footing as a writer (creator? Substacker?). At the very least, it does feel like I'm finally developing some good muscle memory for writing on a weekly cadence.
Waymo vs Uber

2 months ago | thedriverlessdigest.com | Harry Campbell |Timothy Lee

How is Uber not totally screwed by Waymo? I’ve seen this question in one form or another more times than I can count lately. And it’s not just folks on Twitter; almost everyone who’s taken a Waymo has been blown away by the product. The ride is smooth, the ‘driver’ is safe, and it feels like you’re in the future. There’s a reason why I have a section in each week’s newsletter dedicated to peoples’ first AV rides - Waymo is a magical experience.

Why AI language models choke on too much text

Dec 20, 2024 | arstechnica.com | Timothy Lee

Compute costs scale with the square of the input size. That's not great. Large language models represent text using tokens, each of which is a few characters. Short words are represented by a single token (like "the" or "it"), whereas larger words may be represented by several tokens (GPT-4o represents "indivisible" with "ind," "iv," and "isible"). When OpenAI released ChatGPT two years ago, it had a memory—known as a context window—of just 8,192 tokens.

Nov 11, 2024 | arstechnica.com | Timothy Lee

"You’ve taken this idea way too far," a mentor told Prof. Fei-Fei Li. During my first semester as a computer science graduate student at Princeton, I took COS 402: Artificial Intelligence. Toward the end of the semester, there was a lecture about neural networks. This was in the fall of 2008, and I got the distinct impression—both from that lecture and the textbook—that neural networks had become a backwater.
