An engineering team is designing a language model and is considering two approaches for the memory component (Mem) in the attention operation Att(q_i, Mem).

• Approach 1: The memory component Mem consists of the complete, unaltered set of all key and value vectors generated up to the current position i.
• Approach 2: The memory component Mem is a compressed, fixed-size summary of all key and value vectors generated up to the current position i.

Evaluate the primary trade-off between these two approaches, considering both computational resource usage during text generation and the potential impact on the model's ability to handle long-range dependencies in the text. Justify your evaluation.
