this is actually a pretty reasonable plain english summary of modern(ish) recsys. matrix factorization -> collaborative filtering -> iterative candidate generation and filtering -> a/b testing -> cohort filtering and expansion -> iterative signal based rerank

very good mech interp research. excited to see real focused attention here and have been very impressed with the work from goodfire generally

this plus the zurich crew is even more impressive than the thinky departures. strong focus on multi-modal and reasoning

im trying to build tools that support dark mode and light mode to a reasonable degree. as a result i've started using 'system theme' which switches me from light -> dark at sunset. This is my personal hell. i do no recommend this to anyone ...

This is one of the most interesting papers ive read in a long time. not only in terms of token efficiency but also in terms of potential interesting latent interactions with the higher order trilinear representations. arxiv.org/abs/2507.02754

2017 - 2022 is when interesting things were still being published (but not yet tested at scale) and then most were summarily forgotten in the race to clone chatgpt starting in 2023
