Qwen3-30B-A3B-Instruct-2507-ScatterMoE

Qwen3-30B-A3B-Instruct-2507-ScatterMoE

Re-packed weights of Qwen/Qwen3-30B-A3B-Instruct-2507 using Charles Goddard's remote code implementation of scattermoe, including scripts to convert to and from standard Qwen3MoeForCausalLM. Thank you to intervitens for assistance with memory-efficient conversion scripts!

This is intended to be used as a drop-in replacement for efficient training using any transformers-based training repository.

Optional monkeypatches included for Liger Kernel and Cut Cross-Entropy. Simply rename the relevant modeling file to modeling_qwen3_shared_moe.py.
