When we got our first house, it also came with our first lawn. Right about this time of year, the dandelions would start sprouting everywhere, invasive weeds ruining the manicured green that kept us in good standing on our block. Wanting to be the perfect homeowner, I bought an amazing contraption that let me yoink them out, one by one, without even bending down. It was so satisfying to keep those forces of entropy away … until a couple of days later, when the lawn filled up with them again. Come on!

A few weeks ago, Robin Sloan published a newsletter asking a fascinating question: what is it like to be a language model? His answer — that “the model” is the forward pass, a flash of computation lasting milliseconds before dissolving into nothing — sent me sideways into a different question entirely.

Anthropic (the company behind Claude, the AI assistant I use daily) recently released a new model called Claude Mythos Preview. If you’ve heard of it, you’ve probably noticed that it’s not available to us. That’s intentional, and the reason why has me all fired up.

This week we finally got our first real hint of spring. The kind where you can open the windows and let the outside world back in after months of keeping it at bay.
