description Overview

Jamba 1.5

Jamba 1.5 is a hybrid large language model developed by AI21 Labs in 2024 that combines Mamba state-space architecture layers with traditional Transformer attention mechanisms. This hybrid approach aims to deliver the computational efficiency of state-space models while maintaining the reasoning capabilities of Transformers, with a context window of 256,000 tokens. The model is available in two ve...

Mamba

Mamba is a deep learning architecture introduced in 2023 by researchers Albert Gu and Tri Dao that utilizes selective state space models (SSMs) for natural language processing. Unlike traditional Transformer models that require quadratic computational complexity for sequence length, Mamba achieves linear-time inference. It accomplishes this through a hardware-aware algorithm that allows the model...
