NanoGPT Slowrun: 10x Data Efficiency with Infinite Compute
We've achieved 10x data efficiency with NanoGPT Slowrun within a few weeks. An ensemble of 1.8B parameter models (18B total params) trained on 100M tokens matches what would normally require 1B tokens with a standard LM baseline. Data efficiency matters because compute grows much faster than data . Since our current…

I personally find it neat though --- it does this weird thing that I wanted to do for ages, that to my knowledge no one else is doing properly, and implements it better than I…

The Economic Complexity of the Western Roman Empire
I am one of those people who think about the Roman Empire daily – possibly out of my worrying addiction to Crusader Kings III and similar games. I also spent some time working on estimating economic complexity , a neat measure that can be used to explain economic development trajectories. One fateful day, I was…
