With figures the reader can set and the full paper as PDF.
- XE4-S: Dense Composition after a Routing Collapse at N = 3Our previous architecture selected among specialists and collapsed past three of them: top-1 route accuracy of 100%, 23.3%, 36.7%, 36.7% and 46.7% for N of two through six, a code specialist dead at 0% from N = 5, and a learned replacement router at exactly 0.0 bits of mutual information. XE4-S composes thirty-one specialists densely and selects nothing. It routes 18 of 19 task shapes in distribution, gives twelve untrained specialists exactly 0.000 weight, and still loses to a 17M dense monolith on real phrasings, 62% against 100%. Both sides measured by the same lab, the failing side published first.
- XE5: a language model you can teach without breakingXE5, eXtended Episodic Sophia, is a 147.5 M-parameter language model trained from scratch with no pretrained base. A mixture of experts computes w = gate(x), so the same sentence routes the same way for ever. XE5 computes w = compose(x, m), where m is where a beam descent through a memory of runtime-written facts lands. Attaching a new specialist moves the output by 5.96e-07 and attaching the third ring by exactly zero, so a capability can be added to a running model without disturbing anything it already knew. Five live console captures show the composition weights and the memory descent on every turn.
