A Model Family and a Retrieval Layer
AI21 moved beyond offering language models alone by putting Jamba and retrieval tooling on its API platform. Teams could work with the model family and add a layer that supplies material from their own information sources.
AI21 Labs Competitive Landscape
How Models Fit into Enterprise Retrieval
AI21 and Cohere pair proprietary model families with enterprise retrieval tooling. A practical point of comparison is whether Jamba or Command fits a team’s retrieval pipeline and the interfaces the team already uses to get relevant text into a response.
