Sereact x NVIDIA x Nebius closed training loop for Cortex

Track; not yet

Why

The loop connects real returns-station episodes to sim variants (Isaac Lab, Cosmos), Blackwell post-training of Cortex, a held-out gate and a real-world test, run by a cost-previewing agent. It is available now as a Nebius reference architecture, and press reports say Sereact robots already sort Zalando returns at CEVA sites. Every performance claim is from vendor press material, with no accuracy, throughput or station counts and no independent validation. It is credible and real but unproven in outcomes.

Next

Watch for measured returns-handling results (pick success rate, update cycle time), the number of CEVA/Zalando sites, and uptake of the Nebius reference architecture by other robotics teams.
