A company is building an AI application to summarize books of varying lengths. During testing, the application fails to summarize some books.

Why does the application fail to summarize some books?

  • A. The temperature is set too high.
  • B. The selected model does not support fine-tuning.
  • C. The Top P value is too high.
  • D. The input tokens exceed the model’s context size.

Selected Answer: D
Modelos de linguagem como GPT, Claude, ou outros LLMs têm um limite máximo de tokens que podem ser processados por vez — isso é chamado de tamanho do contexto (context window). Um "token" pode ser uma palavra, parte de uma palavra ou pontuação. Se o número de tokens do livro ultrapassa esse limite, o modelo não consegue processar o conteúdo completo, resultando em falhas ou resumos incompletos. Esse é o motivo técnico mais comum para falhas ao tentar resumir textos muito longos como livros inteiros.

Selected Answer: D
Language models like GPT have a maximum context window (measured in tokens). If a book is too long, and its tokenized version exceeds this limit, the model cannot process it in a single input. This causes the application to fail when trying to summarize very long books in one pass. A. Temperature too high – Affects randomness/creativity, not the ability to process inputs. B. Model not supporting fine-tuning – Not relevant to failure in summarization during inference. C. Top P too high – Like temperature, affects diversity, not input size handling. So, D is the root cause when the model fails due to input length.
