AI21 Labs, a prominent AI startup, has launched Jamba, a groundbreaking text-generating and -analyzing model that sets a new standard for the industry. The model, designed to handle extensive context, boasts the capability to write text in multiple languages such as English, French, Spanish, and Portuguese. What sets Jamba apart is its innovative use of transformer and state space models (SSMs), promising greater efficiency and throughput. Unlike its counterparts, Jamba harnesses the power of SSM architecture, delivering impressive three times the throughput on long contexts compared to transformer-based models of similar sizes. Furthermore, Jamba's release under the Apache 2.0 license paves the way for potential future developments. However, it's important to note that this cutting-edge model is currently a research release without safeguards for commercial use. AI21 Labs' introduction of Jamba proves to be a significant step in revolutionizing the AI industry, demonstrating the potential for even further improvements in the near future.
