Retail doesn’t need virtual mirrors; it needs faster, more relevant decisions. That’s Macy’s “AI-first” bet, where artificial intelligence is not a decorative feature but the architectural principle of the entire organization. Murali Murugan, senior director of engineering, describes the shift: “It’s not about adding intelligence on top of existing systems, but about redesigning how decisions happen so the business moves faster and every experience feels more relevant by default.” This philosophy is quietly reshaping personalization, search, operational planning, and even software development.

From pilot to infrastructure: AI becomes the backbone

For many retailers, AI adoption remains a carousel of proof of concepts. Macy’s took a different path: start with high-impact, immediate use cases – search recommendations and customer engagement – and use them as catalysts to win business buy-in for scaling. “Once we established the quick wins, scaling was a business decision, not a technology debate anymore,” Murugan says. That early momentum now flows into tools like Ask Macy’s, a conversational assistant that behaves more like a personal stylist than a search bar. Customers describe their needs – an outfit for a wedding, a vacation wardrobe – and receive curated suggestions cross-referencing purchase history, preferences, and context.

The invisible challenge: where does the intelligence run?

If AI becomes the connective tissue of operations, the question of where inference takes place gains strategic weight. Embedding language and recommendation models directly into business processes means handling proprietary data – purchase behavior, logistics, transactions – that may not always travel to public clouds without friction from latency, cost, or compliance. This is not a technical nuance: it’s the difference between a reactive system and a truly adaptive one. Macy’s “AI-first” approach, while not publicly detailing its infrastructure, raises a central theme for anyone evaluating on-premise or hybrid deployments: total cost of ownership (TCO) and data control become variables as critical as model accuracy.

Data sovereignty and the continuous improvement loop

Murugan emphasizes continuous improvement: “The real transformation comes from learning from mistakes, quickly adapting to newer technology standards, and making sure timing and execution compound into a meaningfully better customer experience.” This process demands a tight feedback loop where models are retrained on fresh, often locally generated data. In scenarios governed by GDPR or where sales data intellectual property is sensitive, keeping inference and fine-tuning on local servers or at the edge can reduce exposure risk and dependence on external vendors. It’s not ideological; it’s operational pragmatism. For retailers now exploring conversational tools and personalized recommendations, the choice of execution platform is not separate from the AI strategy – it is an integral part of it.

Beyond the pilot: the platform as competitive advantage

The Macy’s story suggests that true AI maturity in retail isn’t measured by launching a talking assistant but by the ability to compress “the gap between the signal and the action” through integrated systems. For technology decision-makers, this means evaluating hardware and software stacks that ensure rapid updates, low latency, and data sovereignty, without turning every experiment into a labyrinth of cloud integrations. Whether opting for an on-premise GPU cluster running quantized Large Language Models or a hybrid approach, the principle remains: AI must become so pervasive that it disappears, yet its infrastructural foundation must remain solid and under control. That is the most pragmatic lesson from a giant like Macy’s: AI-first is not a software upgrade, it’s an architectural commitment that starts at the silicon and reaches all the way to the customer experience.
