Expands the script
mergekit-moeto support two new output architectures, Deepseek MoE and Qwen 2 MoE.Both architectures include support for "shared" experts. Currently the script supports adding a single shared expert. The Deepseek architecture uses the shared experts ungated and unweighted, so you probably want to set the new
residual_scaleoption on the shared expert to a relatively low value (think 0.1ish) to keep the model from being completely overcooked. Qwen 2 MoE has a gate parameter associated with the shared expert so this is less necessary, but still advisable.Deepseek MoE supports either Llama or Mistral based models as inputs.
Qwen 2 MoE supports Llama, Mistral, or Qwen2 based models.
Addresses #117, #244, and #134.
