Denver has become one of the first US cities to formally embed artificial intelligence into its top technology leadership, with Suma Nallapati’s role expanded from Chief Information Officer to Chief AI and Information Officer.

The new title reflects the city’s ambition to be seen as the nation’s most forward-thinking AI city and to ensure that technology is deployed in ways that are equitable, secure, and centred on residents.

“Implementing AI across city government inherently presents a few risks–bias and equity, transparency and accountability, and security and data protection,” Nallapati (pictured) told Cities Today. “My strategic approach aims to mitigate these risks by diving in with eyes wide open.”

Nallapati pointed to the city’s AI Request for Proposals as a major milestone. The initiative is designed to create a pool of trusted vendors capable of delivering secure, scalable, and innovative solutions tailored to Denver’s needs.

Following a strong response, the city is now reviewing submissions against criteria such as technical strength, compliance with security standards, scalability, cost, and innovation potential. Each vendor must also complete a detailed risk assessment, which is scrutinised by Denver’s security and privacy teams.

The city’s most visible deployment so far is Sunny, a multilingual chatbot supporting residents via web, text, and WhatsApp. Between January 2024 and September 2025, Sunny engaged with more than 102,000 residents, answered nearly 100,000 questions, achieved a 90 percent satisfaction score, and absorbed 30 percent of daily 311 interactions.

“I believe AI’s success is ultimately defined by how much better it makes life for our teams and the people we serve,” Nallapati said. “With tools like Sunny, we’re tracking the number of residents engaged, our customer satisfaction score, the percentage of daily interactions that are being absorbed by Sunny that would have historically been routed through our 311 call centre, and more. And, since Sunny can recognise 72 different languages, we’re also ensuring the service is accessible and equitable for every Denverite.”

Her wider strategy focuses on transparency and collaboration with an approach to AI that is grounded in active engagement and collaboration.

“We are not just planning transparency; we are practicing it,” she said. “Last year, we successfully launched workshops to boost AI literacy among our city agency, who also contribute their expertise to policy review through our Information Governance Committee.”

Nallapati said Denver is drawing on national best practice by working with universities and foundations, including participation in the Bloomberg City Data Alliance, which is helping shape ethical guidelines and resident data initiatives. At the same time, the city is expanding its existing feedback systems so that residents can directly raise questions about AI, making public input a formal part of how new tools are deployed.

Collaboration with vendors will continue but without ceding control.

“We absolutely need the expertise of partners, but Denver will maintain control and accountability,” Nallapati said.

The city will retain 100 percent ownership of its data and will audit the algorithms, and the city’s in-house team will ensure vendor systems meet standards for ethics, transparency, explainability, data protection, and security.

Nallapati added that Denver aims to set the national pace by embedding AI across every layer of government, from data governance and policy to frontline services.

“Our mission is to seamlessly weave AI into the resident experience,” she said. “Our ultimate goal is to become the blueprint for AI-enabled cities where technology actively enhances equity and access.”

Other US cities and states that have already added, or plan to add, significant AI roles to their workforce include Louisville, New York State, Montana and New Jersey.
