Factoring RSA-260 | Cognition

💥 Check out this awesome post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: By Eric Lu09.09.26Over the past few weeks, the Cognition research team and I have been optimizing our job scheduler to better use disaggregated compute. As a proof of concept, and because I’ve enjoyed factoring numbers as a hobby for the past ten years or so, I drove a bevy of Devins to obtain a factorization of RSA-260. In order to do this, my Devins built the world's highest-performance GPU lattice siever, which enables factoring numbers at 10x lower cost than the previous public state…

A Stupid Idea for AI Alignment We Came up with by Looking at the List of Specification Gaming Behaviours – SLIME MOLD TIME MOLD

🚀 Discover this must-read post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: Creatures bred for speed grow really tall and generate high velocities by falling over. An evolved player makes invalid moves far away in the board, causing opponent players to run out of memory and crash. A game-playing agent accrues points by falsely inserting its name as the author of high-value items.  These bizarre exploits and dozens more can be found in the list of specification gaming behaviours [sic; British], a document put together by DeepMind Safety Research. “A reinforcement learning agent can find a shortcut…

Training a 3.8B LLM to 0.384 CORE for $998

✨ Read this insightful post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: Somewhere between “nanoGPT toy” and “you need a research lab” there’s a large, under-described region where one person with a few thousand dollars can train a meaningful model. I wanted to see language and understanding emerge from random weights for myself, and to learn the parts you can only learn by starting from scratch. This project was written in the evenings, debugged on a 5090 and finished on rented B200s. It was heavily inspired by Andrej Karpathy’s nanochat. The result is a 3.8B-parameter model scoring…

🚀 Explore this insightful post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: Opinion writer and economist Noah Smith just dropped an article about AI-designed superviruses. Oh man. I used to think Smith was a person with informed opinions, but reading his take on a topic close to my own expertise makes me question this premise. No worries though.
