Samba
Overview :
Samba is a simple yet powerful hybrid model with infinite context length. Its architecture is straightforward: Samba = Mamba + MLP + Sliding Window Attention + Hierarchical MLP Stacking. The Samba-3.8B model was trained on the Phi3 dataset with 32 trillion tokens and significantly outperformed Phi3-mini on major benchmark tests (e.g., MMLU, GSM8K, and HumanEval). Samba can also achieve perfect long-context retrieval ability with minimal instruction tuning while maintaining linear complexity with respect to the sequence length. This enables Samba-3.8B-instruct to excel in downstream tasks such as long-context summarization.
Target Users :
The Samba model is primarily aimed at researchers and developers in the field of natural language processing and machine learning. It is suitable for users who need to process large volumes of text data, perform complex language model training, and evaluation. Samba's long context handling capability and efficient computational performance make it an ideal choice for researching and developing advanced language models.
Use Cases
Researchers leverage the Samba model to achieve breakthroughs in long text summarization tasks.
Developers utilize Samba for training and optimizing large-scale language models, enhancing model performance.
Educational institutions adopt Samba as a teaching tool to help students grasp complex language model architectures and training processes.
