AI21 Labs

AI21's Latitude case describes launched production models for AI Dungeon, with a transition from Jurassic-1 Jumbo to Grande and a named customer product executive discussing cost optimization and ongoing updates.

AI21 released Jamba2 as an open model family optimized for enterprise reliability, grounding and instruction following, and positions Jamba for secure production enterprise workflows.

AI21 released Jamba2 3B and Mini model sizes under Apache 2.0, making downloadable model experimentation available beyond its hosted service. This concrete access and licensing fact supports an analyst inference of portable model-deployment and experimentation skills; it does not demonstrate employee career outcomes.

AI21 work spans model architecture, agent evaluation, MLOps, enterprise solutions and production AI systems, providing broadly transferable applied and systems-AI experience.
