Inference Optimization

Inference optimization refers to the collection of techniques used to reduce the computational cost, latency, and memory footprint of running a trained AI model in production — the phase called inference, as opposed to training. Common methods include quantization (reducing numerical precision of model weights), distillation (training smaller models to mimic larger ones), batching, caching, and hardware-specific kernel optimization.

For commerce platforms, inference optimization is operationally critical. Large language models are expensive to run at scale; optimizing inference directly affects cost-per-query, response time, and the feasibility of real-time applications like conversational search, live product recommendations, and dynamic pricing. Teams often must balance quality tradeoffs — a quantized model may be 4x cheaper to run but slightly less accurate — making inference optimization a key architectural consideration in any production AI deployment.
