Looped Transformers Enable Depth Extrapolation, Fueling Claude Mythos Architecture Speculation

heghbalz · x · 2026-10-06

Amid speculation that Claude Mythos is a Looped Transformer, new controlled research shows looping enables systematic generalization and depth extrapolation: models can combine knowledge never seen composed together and reason over more hops than seen in training. The team presents at COLM 2026 on Wednesday.
