There's a certain math meme that surfaces periodically on the internet (or one of its variants). It's nothing more but just computing some sums. So, here I ramble about it.

After significant deliberations today I decided to get out of the tech job industry. I just sent the "an update on Mihai" email.
Starting tonight you can find me as a park ranger in Yosemite. That would be a career that cannot be impacted …

I tested 80 models on two simple grid-based problems, asking them to locate 2026 and compute the sum of the neighbors when the numbers are placed in a spiral on the grid. The results surprised me, as models performed better on the problem …
New year, new problems to test the LLMs on: arranging the numbers on a spiral, what is the sum of the neighbors of 2026? Read on for more details and some preliminary results, as well as how to suggest other LLMs to test: https://mihai.pag…

On today's installment of "blog-every-day-until-xmas", I talk about how Anna Karenina applies to the basics of linear algebra (or am I?) https://mihai.page/anna-karenina-linear-algebra/
Yesterday I delivered the last talk about model signing, finishing the year with the most conference talks for me. I had an amazing time at all these events throughout the year and it's been awesome to see how we went from releasing model …

Happy new year. Since 2025 is a perfect square (45 * 45), let 2025 be a perfect year for you too!
I know I want to manage my time better this year, do more OSS contributions (2853 on GitHub in the past year), read more books (barely 22), m…
Happy (10+(9+8*7)*6)*5+4*3*2*1!
