Differentiating Bottlenecks in Long-Sequence LLMs
A standard Transformer-based Large Language Model faces two primary architectural challenges when processing very long sequences: the computational cost of its attention mechanism and the memory usage of its key-value (KV) cache. Explain how these two challenges create distinct problems for the model's practical application, specifying which is primarily a time-complexity issue and which is a memory-footprint issue.

Architectural Prioritization for a Long-Context LLM
A development team is attempting to use a standard Transformer-based LLM for real-time analysis of continuous data streams, where the input sequence can grow to hundreds of thousands of tokens. They encounter two main problems: the time it takes to process each new token increases dramatically as the sequence gets longer, and the system frequently runs out of memory. Which statement correctly analyzes the architectural sources of these two distinct problems?
