Enterprise LLM Gateways: Semantic Caching and Prompt Guardrails Detailed

This technical guide details the implementation of semantic caching and prompt guardrails for enterprise LLM gateways. It outlines an architecture that sits at the L7 proxy layer within Kubernetes clusters, processing inference requests before they reach upstream providers like OpenAI or Anthropic. The system includes stages for authentication, rate limiting, PII redaction, prompt injection filtering, and semantic cache lookups, aiming to reduce costs and latency by caching similar queries based on vector embeddings.
