We're open-sourcing Mixture-of-Kittens (MoK), our MoE training megakernel for NVL72s. It fuses all Mixture-of-Experts communication and computation into a single, fully deterministic kernel, and runs up to 2.37x faster than the strongest public baselines.↗

full initial prompt: “Create a striking data visualization using d3.js. It should be striking and fun for someone who’s on the list to interact with and experience. Fan out subagents for each part and /loop until it’s utterly perfect and compares with the best data viz experienc…↗

I gave Opus 5 a dataset of every certified running streak (including my own) and told it to use D3 to make a striking data visualization. It made an interactive global map, lifespan running graph, start/end date analysis, and much more. Incredible. (approach and links below)↗

Given some of the results I'm seeing recently, it's pretty clear Codex is a good harness. But it will seem primitive in 2-3 months and we're about to go through another major evolution in how we use AI at the frontier. The next generation of models need more than your laptop.↗

Don't use a MacBook air for software development in the AI era. I just discovered that my machine has quietly been thermal throttling aggressively for the last year. This is where it slows down the CPU to cool itself down because it has no fan. This has wasted so much of my time.↗

Diffs you can edit! Edit mode is now in beta on diffs[dot]com, and we want your help to perfect it. We’re running an online hackathon this week. Build something with diffs, and show us what the new edit mode can do. Post your entry in the comments by 5pm PT on Monday August 10…↗

AI has been quietly assembling a complete behavioral record of you. Might be worth opening it. I've created a prompted called 'Reflection Engine'. Here are 22 questions to unlock that data for you:↗

An internal version of our next major model produced 10 new results on long-standing open problems in mathematics and theoretical computer science, using roughly $2,000 worth of tokens at GPT-5.6 Sol API rates.↗

AI forecasting is now approximately superhuman. Today, FutureSearch is exiting our public beta and launching to everyone. FutureSearch is the original AI forecasting company, started in August 2023. We’re currently #1 of 194 in the most competitive AI forecasting tournament, and…↗
