llama.cpp Gets Experimental MoE Expert Expansion
π‘An experimental llama.cpp feature may improve how local MoE models use expert capacity.
β‘ 30-Second TL;DR
What Changed
The custom branch targets Expert expansion for MoE models.
Why It Matters
If the feature generalizes beyond Metal, it could give local inference users another way to optimize or expand expert execution for MoE models. However, the current evidence is preliminary because platform and model coverage remains limited.
What To Do Next
Clone the moex-expansion branch and benchmark one MoE model on your CUDA, ROCm, or Metal setup against your current llama.cpp build.
Key Points
- β’The custom branch targets Expert expansion for MoE models.
- β’Initial testing was performed on Apple's Metal backend.
- β’The developer reports better performance than their DS4 version but needs broader validation.
