## AI overview

The article examines Entropix, an open-source project that changes the sampling step of small language models using entropy and varentropy signals. It explains sampling, pattern matching, and how these signals may steer generation toward lower-entropy choices, while noting that the details remain unclear.

## Source excerpt

Entropix has been getting a ton of buzz lately. With all the hype, it's hard to tell if there's anything real that's worth paying attention to.
