AI models increasingly require expert human data, real-world training environments, and contextual evaluations to advance beyond current capabilities. Frontier labs and enterprises struggle to source high-quality, domain-specific data and lack the infrastructure to evaluate agentic AI performance in production-like settings, limiting model reasoning and real-world deployment.
micro1 provides an integrated platform for generating expert human data and evaluating AI systems. Its Realm product offers reinforcement learning environments that mirror real-world scenarios to generate world-class human data for agentic actions and elevate model reasoning. Cortex serves as a contextual evaluation platform for improving AI agent performance in production, while Robotics delivers high-fidelity, expert-demonstrated data for frontier robotics labs. The company also operates a research lab focused on solving coordination challenges, including the Medical Index, which brings medical benchmarks together in one place.
Primary customers are AI labs, frontier model developers, and enterprises building agentic AI systems that need expert human data, real-world training environments, and production-grade evaluation tools. The platform also serves government and defense customers, as well as healthcare and robotics organizations.
