Description
AI21 Labs is an Israeli foundation model company founded in 2017 by Yoav Shoham, Ori Goshen, and Amnon Shashua. Its Jamba family combines Mamba state-space layers with Transformer attention, which extends usable context length while holding memory cost down on long documents. Models are served through the AI21 Studio API and the major cloud marketplaces, with private deployment offered for regulated enterprise workloads. The company also builds task-specific systems for enterprises in finance and other regulated sectors where grounding and accuracy carry weight. Its research team published early work on combining neural models with symbolic reasoning.
