A product recommendation app uses a generative AI model. The company wants to minimize the application’s environmental footprint. Which approach best meets that goal?

Optimizing the deployed model architecture for computational efficiency during inference directly reduces the energy consumption and, consequently, the environmental footprint. Efficient models require fewer computational resources (CPU/GPU, memory) to process requests, leading to lower power usage and less heat generation. Using multiple smaller models distributed across Availability Zones might increase redundancy and resilience but doesn't inherently reduce the overall computational load or energy consumption; it could even increase it due to overhead. Deploying on-premises while storing data in AWS introduces a hybrid architecture that doesn't guarantee environmental benefits and might increase complexity and energy use depending on the on-premises infrastructure. Deploying multiple models and randomly choosing among them would likely increase the overall resource consumption, as multiple models would need to be maintained and potentially run, rather than reducing it.
