Semantic Caching for LLM Apps: Cut Token Spend 40-80%
📰 Dev.to AI
Learn how semantic caching can reduce token spend by 40-80% in LLM apps by storing and reusing similar query responses
Action Steps
- Implement semantic caching using a library like Redis or Memcached to store query responses
- Configure the caching layer to store responses for similar queries based on semantic similarity
- Test the caching layer with a dataset of diverse queries to ensure accurate response retrieval
- Apply semantic caching to your LLM app and monitor token spend reduction
- Compare the performance of your app with and without semantic caching to measure the impact on token usage
Who Needs to Know This
Developers and engineers working on LLM applications can benefit from semantic caching to optimize token usage and reduce costs. This technique is particularly useful for support assistants and chatbots that handle repetitive queries

Originally published on AI Tech Connect . What semantic caching actually is Most LLM applications answer the same questions over and over, phrased slightly differently each time. A support assistant fields "how do I reset my password", "I forgot my password" and "can't log in, need a new password" as three distinct requests, and pays for three full inferences to
