2. 推理效率

1. 代码生成能力
# 示例生成快速排序代码
DeepSeek输出
def quick_sort(arr):if len(arr) 1:return arrpivot arr[len(arr)//2]left [x for x in arr if x pivot]middle [x for x in arr if x pivot]right [x for x in arr if x pivot]return quick_sort(left) middle quick_sort(right)ChatGPT输出
def quicksort(array):if len(array) 2:return arrayelse:pivot array[0]less [i for i in array[1:] if i pivot]greater [i for i in array[1:] if i pivot]return quicksort(less) [pivot] quicksort(greater)差异分析DeepSeek更偏向工程实践使用中间位置基准值ChatGPT选择首位元素但缺少相等元素处理
2. 数学解题步骤
题目解方程 x² 2x - 15 0
DeepSeek解答
步骤1识别方程类型 → 二次方程
步骤2应用求根公式 x [-b ± √(b²-4ac)]/(2a)
步骤3代入a1,b2,c-15判别式D 2² - 4*1*(-15) 64
步骤4计算根 → (-2±8)/2 → x13, x2-5ChatGPT解答
整理方程 → x² 2x 15
配方x² 2x 1 16 → (x1)^2 16
开平方 → x1±4 → x3或x-5方法论差异DeepSeek展示标准解法ChatGPT优先使用配方法 五、商业化应用对比
