Request-Response Caching for LLM Inference
A technique used in real-world applications to enhance LLM efficiency by storing frequently made requests and their corresponding model-generated responses. This allows the system to serve subsequent identical requests directly from the cache, thereby bypassing the need for repeated, computationally expensive inference.

Choosing an LLM Optimization Strategy for Deployment
A company has deployed a large language model for a customer support chatbot. They observe that a small number of common questions (e.g., 'What are your business hours?') account for a large portion of the daily traffic. The company is facing challenges with both high operational costs from running the model for every query and user complaints about slow response times. Which of the following deployment-focused strategies would be most effective at directly addressing both the cost and latency issues for these frequent, repetitive queries?
A development team has successfully reduced their language model's size by 50% using a post-training compression method. This single change guarantees that their deployed application will now handle at least twice the user traffic with the same hardware.

Evaluating Caching Strategy for an LLM Application
A company is deploying a large language model for a new application. They implement a performance-enhancing feature that saves a user's exact input prompt and the model's complete generated output as a key-value pair. When a new prompt is received, the system first checks if it exactly matches a saved prompt. If a match is found, it returns the saved output directly, avoiding a new model computation. In which of the following scenarios would this specific optimization strategy be LEAST effective?
