Shopify's post-trained NVIDIA Nemotron 3.5 Lightning models match frontier model accuracy while cutting inference costs by 90% and delivering 7x faster responses.

The model was adapted for Shopify's Sidekick AI assistant. All performance figures cited come from internal Shopify benchmarks.

NVIDIA released these results as part of a Europe-focused retail blog post published the same date. The post also covered retailer use of open models, robotics simulation and digital twins.

Mirakl was separately noted running open models on NVIDIA GPUs via European cloud provider Scaleway, with the company citing data sovereignty and avoidance of vendor lock-in for the deployment choice.
