NVIDIA Highlights European Retail Use of Open Models and Digital Twins

NVIDIA used a Europe retail-focused blog post on Oct. 22, 2026, to highlight how retailers and software companies are applying open models, robotics simulation and digital twins across commerce, warehouse planning and product discovery. The company described a mix of reported production deployments and prototypes, but the examples are vendor-reported rather than independently audited sector data. In the post, NVIDIA said Shopify post-trained its Nemotron 3.5 Lightning model for a GraphQL subagent inside Sidekick, Shopify’s AI assistant for merchants. According to Shopify’s internal benchmark cited by NVIDIA, the post-trained model surpassed a leading frontier model in accuracy while cutting serving costs by 90% and delivering responses 7x faster.
