Building an AI app? Cut down your API costs and speed up response times with an LLM Cache built in Rust!
Every time a user asks your AI a question, it can cost you money and take a few seconds to load. Why pay twice for the same answer?
An LLM cache saves previous answers so you can reuse them instantly!
Here is how a simple cache works in Rust:
-
Exact Match: If the prompt is identical, pull the answer instantly from memory.
-
Smart Match (Semantic): If the prompt means the same thing (e.g., “Hi” vs “Hello”), use a similarity score to find the right answer.
