Analyzing LLM Optimization Strategies
An engineer is considering two different strategies to optimize a large language model's performance for inference.
- Strategy A: Convert the model's parameters to a lower-precision numerical format (e.g., from 16-bit to 8-bit numbers).
- Strategy B: Store intermediate calculations in memory to avoid re-computing them for subsequent steps.
Analyze these two strategies. For each strategy, identify the primary resource it saves and the primary resource it consumes more of. Then, state the fundamental design principle that both strategies illustrate.

LLM Deployment Strategy Analysis
An engineering team is deploying a large language model for a real-time chatbot application on a device with limited processing power but ample available memory. They are considering two approaches for generating responses:
- Approach A: For each new word generated, the model re-processes the entire conversation history from scratch.
- Approach B: The model stores key intermediate calculations from previous words in memory and reuses them to generate the next word.
Which of the following statements best analyzes the trade-offs between these two approaches in the context of the team's hardware constraints?
