+APUS-xDAN-4.0-MOE
+Introduction
+APUS-xDAN-4.0-MOE is a transformer-based MoE decoder-only language model pretrained on a large amount of data.
+
+For more details, please refer to our blog post and GitHub repo.
+
+Model Details
+APUS-xDAN-4.0-MOE employs Mixture of Experts (MoE) architecture, where the models are upcycled from dense language models. For instance, APUS-xDAN-4.0-MOE is upcycled from Qwen-1.8B. It has 14.3B parameters in total and 2.7B activated parameters during runtime, while achieching comparable performance to Qwen1.5-7B, it only requires 25% of the training resources. We also observed that the inference speed is 1.74 times that of Qwen1.5-7B.
+
+Requirements
+The code of APUS-xDAN-4.0-MOE has been in the latest Hugging face transformers and we advise you to build from source with command pip install git+https://github.com/huggingface/transformers, or you might encounter the following error:
+
+ 
+
+Usage
+We do not advise you to use base language models for text generation. Instead, you can apply post-training, e.g., SFT, RLHF, continued pretraining, etc., on this model.
