Building embeddings from abstraction-neuron activations for more consistent vector math

mayfer · x · 2026-10-23

Inspired by @nickcammarata's essay on abstraction features, the author built an embedding engine by composing vectors from common abstraction-neuron activations. In his testing it behaves more consistently, especially for embedding math: less distracted by spelling and formatting, more focused on the abstractions present. It isn't always better but is generally on par, and hasn't broken down into returning junk like regular embedding models. He plans to run vector search evals next.
