NVIDIA supplies the simulation, world models and agent skills. Nebius runs them on its Physical AI Workbench. Sereact's Cortex is the robot brain they train. The initial rollout targets Zalando’s returns handling at CEVA Logistics’ fulfillment center—one of the most variable processes in eCommerce logistics.

BERLIN, Oct. 21, 2026 (GLOBE NEWSWIRE) -- Sereact, NVIDIA, Nebius, CEVA Logistics and Zalando today announced a closed training loop for Cortex, Sereact's robot brain. The first deployment is Zalando returns handling in selected CEVA Logistics fulfillment centers. NVIDIA provides Isaac Sim, Isaac Lab, Cosmos and its Physical AI Data Factory skills. Operated through the company’s EU data centers, Nebius runs them on the Physical AI Workbench, its open-source framework for physical AI. Sereact brings Cortex and the episodes its robots record on the returns line. What a robot gets wrong on Monday can come back as a tested policy update within days, where it used to take weeks.
