2. How LLMs Work (www.0xkato.xyz)

A from-the-ground-up walkthrough of how modern LLMs work, from tokens to transformer blocks to the next-token loop

20. Python JIT project was asked to pause development (discuss.python.org)

We would like to take a moment to talk about the experimental just-in-time compiler in CPython, and the path we think it should take from here. Over the past several years, several core developers and contributors have been building a JIT compiler in the main branch of CPython. We want to begin by thanking them. This has been hard, deeply technical work that has been done with great care, and the recent performance improvements are real and encouraging. None of what follows is a criticism of th...

25. Benchmarks in Leipzig (arxiv.org)

Between April 1 and May 15, 2026, a group of 49 mathematicians compiled a dataset of research-level mathematics questions with known answers. Most of the work was done during the 3-day workshop *Benchmarks in Leipzig* with 35 participants at the Max Planck Institute for Mathematics in the Sciences in Leipzig, Germany. We present the resulting collection of 100 questions. We evaluated these questions in three stages: a single attempt by five state-of-the-art LLMs, followed by a 20-runs-per-model evaluation with three of these models, and finally a 3-run attempt with two heavy-thinking models. After Stage 1, 41 questions remained completely unsolved; after Stage 2, this count dropped to 16; and we concluded Stage 3 with only 2 unsolved questions. This demonstrates that the mathematical reasoning capabilities of LLMs are becoming impressive.

26. You Can Run (magazine.atavist.com)

When their parents ripped two young sisters from their privileged lives, gave them fake names, and took them on the lam, they thought it was because their father was in trouble with the IRS. It would be years before they learned the truth about his life of crime.
