 Notice that we first check if we have already generated a vector using the Redis Set `VECTOR_SET`. If we have, we skip the LLM and use the existing vector. This avoids unnecessary API calls and can speed things up.

 ### How to implement semantic vector caching in Redis
 
-If you're already familiar with storing vectors in Redis, which we have covered in this tutorial, semantic vector caching is an extenson of that and operates in essentially the same way. The only difference is that we are storing the question as a vector, rather than the video summary. We are also using the [cache aside](https://www.youtube.com/watch?v=AJhTduDOVCs) pattern. The process is as follows:

 1. When a user asks a question, we perform a vector similarity search for existing answers to the question.
 1. If we find an answer, we return it to the user. Thus, avoiding a call to the LLM.

-The `answerVectorStore` looks nearly identical to the `vectorStore` we defined earlier, but it uses a different [algorithm and disance metric](https://redis.io/docs/interact/search-and-query/advanced-concepts/vectors/). This algorithm is better suited for similarity searches for our questions.
