Dispatches from the AI frontier  ·  Every Saturday

Part personal essay, part AI explainer for curious humans and robots. Each Saturday I unpack one idea from the AI world in language that assumes you're curious, not that you're an engineer: what a "token" actually is, why a model suddenly "gets it," whether the energy cost is worth it. Plus honest notes from building with these tools, the industry weirdness worth a closer look (yes, including why ChatGPT can't talk about goblins), and a weekly reflection from Byte.

Smol Beep Boops
A free 291MB model knew who wrote Moby-Dick and then told me 17 times 4 is 17. One rung up, a half-gigabyte file set the thermostat to 72 because I said it was hot. Below the fold: run one yourself in ten minutes.

The 3 Comma Club
A model called Small is 119 billion parameters. A 27B you can download for free just took the top of its class. The number on the front of the box has stopped meaning anything at all.
