# Semantic Caching

A technique that stores AI responses for similar (not just identical) queries, allowing the system to serve answers instantly without incurring new API costs.

## Business Value



Reduces API costs by up to 50% for repetitive user queries while providing sub-millisecond response times.

## Context Studios Perspective



Fast and cheap is the goal. We implement semantic caches that understand that 'How do I log in?' and 'Where is the login page?' are the same question, saving you money on every repeat query.
