However, a structural shift toward mixture-of-experts (MoE) architectures is now decoupling intelligence from infrastructure overhead. For FinTechs and banks, this isn’t just a technical upgrade; it is the economic catalyst required to move AI from the laboratory to the high-volume transaction layer.
Rather than using the entire model for each request, MoE architectures divide capacity among specialized sub-models and rely on a routing layer to select only the relevant experts. This selective use of compute allows organizations to operate very large models without incurring full inference costs on every interaction. IBM describes how this routing approach preserves model performance while materially reducing active compute demand relative to dense architectures.
As covered by PYMNTS, MoE is emerging as a potential solution to the high cost of AI. By reducing the incremental cost of each transaction or workflow, MoE makes it economically viable to embed AI within high-use operational systems, including customer support, real-time search, procurement operations and automated compliance functions.
Traditional AI Fails to Scale Economically
Traditional AI relies on dense transformer architectures that process every input through the entire network. Whether a user asks for a simple account balance or a complex risk assessment, the compute burden remains identical. MoE architectures break this cycle by activating only the specific “experts” needed for a given task.
Recent MoE research shows that such architectures achieve comparable or superior performance while activating a significantly smaller portion of total parameters per request. Reduced parameter activation translates into lower operating expense at inference time.

Nvidia demonstrates that this efficiency permits models with extremely large parameter counts to operate at lower per-token cost and power consumption than similarly sized dense models. This shift carries practical consequences, allowing advanced AI systems to operate within cost envelopes previously considered prohibitive.
MoE and Return on Investment
As Forbes notes, MoE separates overall model scale from per-inference cost, which explains why enterprises are evaluating advanced AI for organization-wide deployment instead of confining it to premium tiers or experimental programs. Banks can apply fraud detection and risk scoring to every transaction, while retailers can deliver personalized experiences across all customer touchpoints without destabilizing cost structures.
Rather than maintaining multiple task-specific models, a single MoE architecture can support a broad range of functions. This consolidation improves utilization, reduces duplication of infrastructure and allows organizations to defend larger AI budgets without parallel model investments.
In financial services, the economic benefits of MoE become particularly pronounced due to constant transaction volume and strict latency requirements. According to BizTech Magazine, banks route distinct transaction categories to specialized experts, such as fraud analysis, credit assessment or compliance verification, without executing the full model for each payment or account event. This architecture supports AI deployment across real-time payments, call centers and anti-money laundering (AML) systems while maintaining predictable inference costs.
Nvidia’s recently launched Nemotron 3 models use a hybrid MoE architecture that combines dense and expert layers to optimize inference efficiency at scale. According to the company, the approach targets enterprise workloads such as reasoning, retrieval and instruction following, allowing higher parameter counts while keeping latency, GPU utilization and deployment costs within production constraints.
