Model Selection for Cost

What is Model Selection for Cost?

Model selection for cost refers to the systematic process of evaluating and choosing AI models based on their cost-performance characteristics. This involves analyzing factors such as training costs, inference costs, maintenance requirements, and expected business value to make informed decisions. Effective cost-based model selection requires understanding the unique cost structures of different model architectures, including variable compute costs, memory requirements, licensing fees, and operational overhead that can significantly impact total cost of ownership and return on investment.

Key Factors in Cost-Based Model Selection

1. Performance Requirements

Performance requirements form the foundation of cost-based model selection, providing clear criteria for evaluating model options against business needs. This factor involves defining specific performance metrics that the model must meet, including accuracy thresholds, latency requirements, and throughput expectations that directly impact cost considerations and resource allocation decisions.

• Accuracy benchmarking: AI accuracy assessment platforms such as Weights & Biases for model performance comparison, MLflow for model lifecycle tracking, and Neptune.ai for experiment comparison and cost analysis
• Latency measurement: AI latency testing tools including TensorBoard for model performance analysis, Hugging Face’s Evaluate for model evaluation, and Model Cards for model documentation and performance decisions
• Throughput analysis: AI throughput testing platforms such as TensorFlow Model Analysis for model performance analysis, ONNX Runtime for model optimization, and TensorRT for inference optimization

4. Scalability Considerations

Scalability considerations are critical for ensuring that model costs remain manageable as usage and demand grow over time. This factor involves assessing both horizontal and vertical scaling implications, including infrastructure scaling costs, performance degradation risks, and cost optimization opportunities at scale.
