An Empirical Study of Mamba-based Language Models

Documentation   Paper   Models

Overview

We release the 8B-parameter Mamba-2 and Mamba-2-Hybrid model (made of Mamba-2, attention, and MLP layers) trained for the paper An Empirical Study of Mamba-based Language Models.. These models were trained for 3.5T tokens with a sequence length of 4K. These models can be compared to the released 8B-parameter Transformer trained on the same data with the same hyperparameters. We also release the 32K and 128K long-context extensions of Mamba-2-Hybrid.
