The rapid evolution of artificial intelligence presents a significant challenge for enterprise AI teams: How to build for a future where today’s cutting-edge models may be obsolete within a year? MassMutual is addressing this dilemma not by making long-term bets on specific technologies, but by cultivating an adaptable infrastructure capable of seamlessly integrating next-generation models as the market evolves.
“The world of AI today is extremely dynamic,” Sears Merritt, MassMutual’s CIO, shared on a recent VB Beyond the Pilot podcast. “We wanted to make sure we were positioned to ride that wave of dynamism.”
This strategic approach appears to be yielding substantial results. MassMutual reports a notable 30% surge in developer productivity. Furthermore, AI-driven enhancements in contact center operations have slashed resolution times from approximately 10 minutes to just one minute, while concurrently reducing costs from dollars to mere cents per interaction.
However, the most significant takeaway for IT leaders may lie less in the quantifiable outcomes and more in MassMutual’s deliberate methodology for constructing its AI architecture, with a steadfast focus on user experience.
Preserving Flexibility for Future Innovations
MassMutual collaborates with leading-edge vendors, but maintains strategic flexibility by capping these partnerships. “Those relationships are capped so that we maintain optionality for best-of-breed tools as things mature in this space, and at some point, settle down and stabilize,” Merritt explained.
This philosophy also extends to the integration of open-source models. Merritt confirmed that his team is actively exploring open-source tools, anticipating their crucial role in MassMutual’s future AI utilization, mirroring trends in the broader industry.
“We’re certainly going to need frontier models and leading-edge capabilities to do what today is impossible, and tomorrow will be possible,” he stated, emphasizing the ongoing need for advanced AI functionalities.
Measuring Success From Inception
MassMutual’s AI initiatives are structured into two primary categories. The first category focuses on enhancing employee capabilities by deploying productivity-boosting tools such as Copilot and virtual assistants across the workforce. The second category, termed “deepen and focus” initiatives, involves targeting specific workflows or business processes with the potential for significant positive impact on advisors, policyholders, or internal staff.
Crucially, these projects are not evaluated based on adoption rates alone. Instead, they commence with clearly defined success metrics. “Everything we do is measured,” Merritt emphasized. “There’s always a success metric that we define upfront to determine whether or not we’re going to scale up some of these things.”
The company is also actively fostering an environment of experimentation. Employees are provided access to a spectrum of best-in-class models, advanced “token-consumptive workflows,” and other emerging capabilities. This allows them to assess the value proposition of these sophisticated tools against more accessible, lower-cost large language models (LLMs).
Concurrently, MassMutual is meticulously gathering detailed analytics on usage patterns, developer workflows, model performance, and associated costs. The objective is twofold: to manage and potentially reduce expenditure, and to build operational intelligence that will enable the dynamic routing of workloads to the most appropriate model based on criteria such as cost-effectiveness, response quality, and user experience.
These data-driven insights will ultimately inform critical optimization decisions regarding model selection, prompt engineering, response latency, and the underlying infrastructure design.
“We’re gaining access to analytics that let us, in a very granular way, look at usage patterns, developer workflows, and begin to make sense of who’s using what, when, and for what types of tasks,” Merritt elaborated.
Strategic Trade-offs: Prioritizing Quality Over Cost in Model Selection
An intriguing facet of MassMutual’s strategy lies in its methodology for evaluating AI quality. Moving beyond purely benchmark-driven or cost-per-token metrics, the company employs what Merritt terms a “trust score” framework. This framework integrates user feedback with operational data to gauge employee perception of AI-generated responses and their efficacy in driving desired outcomes.
This framework was rigorously tested during the contact center overhaul. During the development phase, employees were given access to two distinct LLMs. The first model delivered near-instantaneous responses but with variable quality. The second, a more resource-intensive option, required a few additional seconds to process but consistently produced superior outputs.
Contrary to what might be expected based on conventional wisdom and the demand for rapid business processes, users overwhelmingly favored the higher-quality, albeit slower, model. Merritt’s team solicited user input regarding response quality, model preference, and overall user experience.
The consistent feedback was: “We want the more expensive one. We’re willing to wait, but the quality difference is so high that the two extra seconds actually is worth it to us.”
This qualitative user feedback proved decisive in the final model selection. “We factored that experience piece into the decision-making, and that led us to say, on a relative basis, the costs were immaterial, so we’re going to use the more complex model,” Merritt stated.

Business Style Takeaway: MassMutual’s approach highlights the strategic advantage of building flexible AI infrastructure over committing to specific technologies, enabling businesses to adapt to rapid advancements. Prioritizing user-validated quality, even at a slightly higher cost, can lead to more effective AI adoption and ultimately, better business outcomes than solely focusing on speed or immediate cost savings.
