😎 What's Interesting?

Dynamic Mixture of Experts (DynMoE) incorporates (1) a novel gating method that enables each token to automatically determine the number of experts to activate. (2) An adaptive process automatically adjusts the number of experts during training.

Top-Any Gating

💡 Model Details

• 🤔 DynMoE-StableLM is a MoE model with dynamic top-k gating, finetuned on LanguageBind/MoE-LLaVA-StableLM-Stage2.
• 🚀 Our DynMoE-StableLM-1.6B has totally 2.9B parameters, but only 1.8B are activated! (average top-k = 1.25)
• ⌛ With the DynMoE tuning stage, we can complete training on 8 A100 GPUs within 40 hours.
