infoAbout AI21

AI21 is an enterprise AI infrastructure platform that helps teams reduce token costs while maintaining output quality through intelligent routing, workload optimization, and custom-tuned models. The platform centers on three integrated components. The Intelligent Gateway is a drop-in endpoint that routes agent traffic with built-in caching and compaction to cut token waste. The Harness Optimizer searches across thousands of configurations against a customer's private evaluations to find cost-quality trade-offs that meet set ceilings and floors. For established workloads, AI21 distills dedicated small open models that match frontier accuracy at lower cost. Setup requires pointing existing agents at the Gateway, with routing and caching active after two lines of configuration. The company reports most teams see spend reductions within a day. Target users are enterprise teams operating AI agents at scale who need predictable costs without sacrificing reliability. The offering appears to involve consulting engagement for the dedicated model training component. AI21 was co-founded by Ori Goshen and Stanford professor Yoav Shoham, with research backing from advisors across Stanford, Technion, and Hebrew University. The company publishes technical research on routing strategies and cost optimization.
