In his keynote at the RAISE Summit 2025, AI21 Labs co-founder and co-CEO Ori Goshen discusses the challenges of applying AI to complex, multi-step tasks in enterprise settings. He highlights the limitations of relying solely on large language models (LLMs), which, although effective in executing single tasks with about 90% accuracy, struggle with the compounded errors of multi-step processes. Goshen introduces AI21's Maestro, a system designed to address these shortcomings by planning, executing, and validating complex workflows with transparency and reliability. Maestro enables developers to create enterprise-grade knowledge agents capable of generating multiple plans, selecting the optimal one, and providing detailed outputs, thus moving beyond single-turn reasoning to offer a trustworthy solution for businesses.
