Explaining Unexpected Model Performance
A language model was pre-trained exclusively on text segments with a maximum length of 4,096 tokens. During testing, it is tasked with summarizing a 5,000-token document and produces a reasonably coherent summary. A colleague is surprised by this result, believing the model should have failed completely since it never saw a document of this length during its training. Briefly explain the underlying principle that allows the model to handle this longer sequence.

Analyzing Model Performance on Long Documents
An AI development team trains a language model exclusively on documents with a maximum length of 4,096 tokens. After deployment, they are surprised to find that the model can coherently summarize documents up to 5,000 tokens long, but its performance degrades significantly on documents longer than 6,000 tokens. Which statement best analyzes this observation?
