PQCache: Product Quantization-based KVCache for Long Context LLM Inference

Summary: PQCache uses PQ to compress KVCache for long-context LLM inference, treating KVCache as embedding retrieval. During prefilling and autoregressive decoding, PQ codes and centroids approximate key selection to fetch K/V, reducing overhead. (summarized by gpt-5-nano on Feb 09 2026)
