PyTorch

PyTorch-based recommendation inference systems enable efficient production deployment of ML models at scale. The workflow involves transforming trained models through graph capture, optimization passes (fusion, quantization, compilation), and serialization. Key optimizations include GPU acceleration, C++ runtime for high QPS scenarios, distributed inference patterns, AI compilers like AOTInductor, request coalescing, table batched embeddings, and quantization strategies. The system requires a lightweight executor, tensor-based APIs, and DAG execution model. Meta's implementation powers global surfaces like Feed, Ads, Instagram, and Reels, handling diverse architectures from DLRM to DHEN and HSTU.
