10 articles on ml — what drives the cost, how it is priced, and where the savings actually are.
A feature store's cost is the offline store (bulk feature data for training), the online store (low-latency serving for inference), and the compute that materializes features. The online store and materialization drive the bill. Here is the model.
Labeling training data, human annotation, managed labeling services, or model-assisted labeling, is often a large and underestimated ML cost. Active learning, pre-labeling, and scoping the labeled set cut it. Here is how.
A model registry stores versioned model artifacts and metadata; its cost is mostly the storage of those artifacts, which can be large for many versions of big models. Lifecycle policies and pruning old versions cut it. Here is the model.
MLOps cost spans data prep, training, serving, feature stores, registries, monitoring, and orchestration, each a piece of the bill. Serving and training compute usually dominate, but the hidden pieces add up. Here is how to budget the whole lifecycle.
GPU instances vary enormously in cost, from older inference GPUs to top training accelerators costing many dollars per hour. Matching GPU class to the workload, and using Spot, drives the bill. This compares the tradeoffs.
Training cost is GPU-hours: accelerator class times count times training time. Spot with checkpointing, right-sized GPUs, efficient data pipelines, and stopping idle instances cut it sharply. Here is how.
Inference cost is serving capacity times uptime: the accelerators or CPUs kept ready to respond. Autoscaling, right-sized hardware, batching, and scaling to zero when idle cut it. Here is how.
GPUs accelerate inference but cost far more per hour; CPUs are cheaper but slower per request. For small models, low throughput, or latency-tolerant workloads, CPU is often cheaper per inference. Here is how to decide.
Serving a model can use a managed endpoint (SageMaker, Vertex, Azure ML) that bundles ops at a premium, or self-hosted serving on your own compute that is cheaper per hour but adds operational burden. Here is the tradeoff.
Real-time inference keeps serving capacity always ready to respond instantly; batch inference processes predictions in bulk on transient compute. When predictions can wait, batch is far cheaper. Here is the tradeoff.
