Analyzing Pretraining with Layered Metrics
eliebakouch · x · 2026-07-13
The author attempts to correlate public wandb layered metrics with JLens's layered statistics, though no clear correlation has been found yet.
They hope this approach will yield more insights into model internals during the pretraining phase. They also admit that most of their initial hypotheses were wrong, with only one "transfer" hypothesis from fable seemingly holding true.
Additionally, they mention adopting a more time-efficient way of blogging, reducing the writing burden to better reflect their actual thought process.
