Custom llama.cpp Branch Adds Expert Expansion for MoE Models

Specific-Tax-6700 · reddit · 2026-09-07

A developer built a custom branch of llama.cpp (with help from GLM 5.3 Flash) that supports expert expansion for MoE models. Tested only on Metal so far, and it works better than the author's earlier DS4 version.

The branch is open-sourced with docs, and the author is looking for feedback from other platforms and different models.
