What is AI21 Labs?
AI21 develops enterprise AI systems and foundation models. Intelligent Gateway is a drop-in endpoint that existing agents can switch to, and it reduces token costs and waste through routing, caching, and compression. Once the workload is defined, it builds a dedicated model by tuning a small open model to the customer's tasks. It sells the Jamba Mini and Jamba Large foundation models through an API on a pay-as-you-go basis.
