Cost Levers

What are Cost Levers?

Cost levers are adjustable parameters, policies, and strategies that directly impact the financial expenditure of AI and ML operations. These levers can be pulled or adjusted to increase or decrease costs based on organizational priorities, budget constraints, and performance requirements. Effective cost lever management requires understanding the unique cost structures of AI systems, including GPU/CPU utilization costs, model training and inference expenses, data storage and processing fees, and API usage costs that can vary significantly based on workload patterns and system complexity.

Key Cost Levers in AI Operations

1. Model Selection and Architecture

Model selection and architecture choices form the foundation of cost optimization in AI systems. Choosing between different model sizes, architectures, and complexity levels directly impacts compute costs, training time, and operational expenses. This lever enables organizations to balance performance requirements with cost constraints through strategic model selection.
