Key points

  • Semantic caching returns a cached response when a new query's embedding is above a cosine similarity threshold — phrases the same question differently and still hits the cache
  • Never share semantic cache entries across users for personalized or user-specific responses
  • Production agents need hard caps: max iterations, wall-clock timeout, cost budget, and human-in-the-loop for irreversible tool calls
