## 📰 News

- **[2024.05.31]** 🔥 Our [code](https://github.com/LINs-lab/DynMoE/) is released!
- **[2024.05.25]** 🔥 Our **checkpoints** are available now!
- **[2024.05.23]** 🔥 Our [paper](https://arxiv.org/abs/2405.14297) is released!

## 😎 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.

## 💡 Model Details

- 🤔 DynMoE-Qwen is a MoE model with **dynamic top-k gating**, finetuned on [LanguageBind/MoE-LLaVA-Qwen-Stage2](https://huggingface.co/LanguageBind/MoE-LLaVA-Qwen-Stage2).
- 🚀 Our DynMoE-Qwen-1.8B has totally 3.1B parameters, but **only 2.2B are activated!** (average top-k = 1.86)
- ⌛ With the DynMoE tuning stage, we can complete training on 8 A100 GPUs **within 40 hours.**
