Animated trace shows Opus 4.6 multiplying two 128-digit integers

Developer ctjlewis shared an animated trace diagram of Claude Opus 4.6 computing the product of two 128-digit integers, visualizing the model's internal computation as part of an upcoming paper.
Quoting a debate about whether we truly understand how LLMs work, the author argues the field underappreciates such work: the paper covers two years of computational experiments across several generations of models, which he calls cooler than most academic literature focused on what models supposedly cannot do. He also shared the general form of the multiplication algorithm the model appears to use.
