This flexibility is designed to accommodate the rapid evolution of AI architectures, from [transformer](https://www.wikiprompt.org/wiki/transformer)-based [large-language-model](https://www.wikiprompt.org/wiki/large-language-model)s to convolutional networks.

Its hardware platform is built around the Reconfigurable Dataflow Unit (RDU), a processor architecture intended to improve data movement and computation for AI workloads. The RDU integrates large on-chip memory and a grid of processing elements that can be dynamically connected. This design reduces the need to move data between separate memory and compute units, a key bottleneck in traditional von Neumann architectures.

The company offers cloud and on-premises systems used for AI inference and model deployment. The software stack includes the SambaNova Suite, which provides tools for model compilation, optimization, and serving. This integrated approach aims to simplify the deployment of [deep-learning](https://www.wikiprompt.org/wiki/deep-learning) models, reducing the engineering effort required to achieve high performance.

SambaNova's technology is particularly focused on inference workloads, where latency and throughput are critical. The company claims that its systems can deliver competitive performance on [generative-ai](https://www.wikiprompt.org/wiki/generative-ai) tasks while using less power than comparable GPU clusters. This efficiency is achieved through the dataflow architecture, which eliminates many of the overheads associated with instruction-based processors.
