The code behind the writing.

The code behind the writing. Every figure and every number on this site regenerates from one of these repositories.

mc-radiative-transfer

Monte Carlo radiative transfer through a scattering atmosphere. Reproduces Chandrasekhar's H function, and the pulse machinery matches published reference waveforms to 0.11%.

IOI

Direct logit attribution, activation patching and path patching over GPT-2's IOI circuit. Four notebooks; every figure in the post regenerates from one cached run.

QuotesByNiche

A character-level transformer trained on Nietzsche, and the head analysis that found a copying circuit with half a bracket-completion mechanism in it.

mem-toy-scratch

The memorisation-challenge sweeps: the bias split, the transplant control, and the dead-unit census behind the absorbing-state result.

jacobian-lens-from-scratch

Reimplementing the global-workspace result from scratch. In progress — this is the experiment the homepage names.
