To deploy an AI model for real-time predictions accessible via RESTful APIs and requiring auto-scaling based on demand, which GCP service is the best choice?

*AI Platform Predictions with AutoML is the best choice for deploying an AI model that requires real-time predictions, accessibility via RESTful APIs, and auto-scaling based on demand. This service is fully managed, taking away the complexities of infrastructure management. It supports auto-scaling to handle varying loads efficiently, ensuring that resources are optimized as per the demand. AI Platform Predictions with AutoML also allows easy integration with RESTful APIs, providing a straightforward way to access the model for predictions. In contrast, options like Cloud Functions, Kubernetes Engine, App Engine, or Cloud Run, while powerful, either require more manual intervention for scaling and management or are not as optimized for machine learning workloads and the specific requirements of easy accessibility and auto-scaling.*
