Correct Answer

Implement a Semantic Caching layer (e.g., using Redis) to store and retrieve past completions based on prompt vector similarity

Why This Answer Is Correct

Semantic caching stores past user prompts and completions. When a new prompt is received, it generates an embedding and checks similarity. If there's a highly similar query, it returns the cached completion, bypassing the OpenAI API to save tokens and minimize latency.
