Report: GKE Inference Gateway delivers up to 92% faster AI responses

GKE Inference Gateway optimizes large language model (LLM) inference performance through intelligent request routing and prefix caching technology.

• •Uses model-aware routing to match requests to pre-warmed GPUs/TPUs, reducing accelerator recomputation and latency
• •Implements prefix caching to store and reuse KV cache of repetitive prompt prefixes across requests
• •Enables efficient RAG-based documentation Q&A and multi-turn chat with cached system prompts and context
• •Delivers 15.7% higher throughput, 92.8% faster time to first token (TTFT), and 62.6% lower inter-token latency (ITL) compared to standard Kubernetes load balancing
• •Achieves 75-80% prefix cache hit rates in production environments like Snap Inc.
