GPT（Generative Pre-trained Transformer）是一种基于Transformer架构的大型语言模型。它由OpenAI开发，通过预训练的方式能够理解和生成人类语言。GPT模型的一个应用实例是“GPT Calculator”，这是一个使用GPT技术来执行数学计算的在线工具或应用程序。下面将详细介绍GPT Calculator的功能、工作原理以及可能的局限性。

功能概述

GPT Calculator可以看作是一个结合了自然语言处理和数值运算的工具。用户可以通过输入一段描述性的文字来表达他们的计算需求，而GPT Calculator会尝试理解这些指令并给出相应的结果。例如，用户可能输入如下问题：

plaintext
What is the sum of three and five?

或者更复杂的例子：

plaintext
If I have $10 in my pocket, and I spend $3 on a snack, how much money do I have left?

GPT Calculator应该能够正确解读这些问题并提供正确的答案：

“`plaintext
The answer to your first question (“What is the sum of three and five?”) is eight.
For your second scenario (spending money from your pocket), you would subtract the amount spent from the initial amount:
$10 – $3 = $7. Therefore, after spending $3 on a snack, you would have $7 left in your pocket.
