2024年您产品必备的10大AI API推荐
探索AI编程前沿：DeepSeek、CodeLlama、GLM与ChatGPT系列大模型Java编码能力测评
2024-11-22
一、前言
去年8月份Meta开源Code Llama 7B/13B/34B系列时，做过一个关于Code Llama和ChatGPT的Java编码能力测评。当时Code Llama使用的是34B Instruct版本，ChatGPT使用的是3.5版本，结果显示Code Llama 34B Instruct相比ChatGPT3.5，还是有一些差距，特别是中文理解方面不够理想。
到今年2月，几个月时间里，大模型如雨后春笋、层出不穷，随着版本迭代，智能水平快速发展。1月16日智谱发布GLM-4，1月29日Meta开源其代码大模型的最大参数版本Code Llama 70B，2月4日阿里发布QWen1.5。
在这些最新大模型中，本次选取了五个排名和评分靠前的大模型：EvalPlus排行榜HumanEval排名仅次于GPT4的代码大模型DeepSeek-Coder-33B-Instruct、最新发布的主流代码大模型CodeLlama-70B-Instruct、最近风头正盛的智谱GLM-4、大家使用最多的ChatGpt3.5、公认最强的ChatGPT4，来看下在Java编码能力方面表现如何，希望能对代码大模型的选型起到一定参考作用。
二、本次测评大模型简介
1、DeepSeek-Coder-33B-InstructDeepSeek
是知名私募巨头幻方量化旗下的人工智能公司深度求索。据国盛证券研报，在云算力端，目前国内只有商汤、百度、腾讯、字节、阿里和幻方有超过1万张A100芯片储备，可见幻方的硬实力不容小觑。23年11月开源了代码大模型DeepSeek Coder，包括7B和33B，支持免费商用。在EvalPlus排行榜(https://evalplus.github.io/leaderboard.html)上，DeepSeek-Coder-33B-instruct在HumanEval paas@1评分75.0分，仅次于GPT-4-Turbo(Nov 2023)的81.7分和GPT-4(May 2023)的79.3分，超过GPT-3.5-Turbo (Nov 2023)的70.7分和GPT-3.5 (May 2023)的66.5分，位列第三名。

2、CodeLlama-70B-Instruct
1月29日Meta新开源的代码大模型CodeLlama-70B-Instruct，可以说从去年8月到现在，半年磨一剑。在EvalPlus排行榜(https://evalplus.github.io/leaderboard.html)上，最新的CodeLlama-70B-Instruct的HumanEval paas@1评分58.5分，低于GPT-3.5，相比CodeLlama-34B-Instruct进步不少。

3、GLM-4
GLM-4是智谱1月16日新发布的第四个版本，前三个版本是开源可免费商用的，GLM-4目前没有。根据GLM-4发布会介绍，与ChatGLM3相比，GLM-4在综合能力上实现了全面跃升，性能提升了60%，号称已经逼近GPT-4，估计是要开始变现了。

4、ChatGPT
ChatGPT目前有4和3.5两个版本。GPT4是业界公认最强者，基本上是一直被模仿，从未被超越，但是一分钱一分货。本次测评使用的是GPT4是GPT-4-0613版本。GPT3.5是目前使用人数最多的，性价比高，智能方面表现一直也是靠前的，传说已经被很多竞争对手超越了。

三、Java编码能力测评
Linus说过：Talk is cheap. Show me your code。多说无益，我们直接上代码来测评下Java编码能力，按运行结果的正确性、生成代码的正确性、代码风格是否清晰简洁、代码的复用性、代码的注释可读性几个维度进行分析，使用100分制打分。
1、测评一：日期工具类代码生成
测评一来源于实际工作中遇到的一个开发场景，需要生成根据当前日期返回对应不同月度、年度范围的四个维度的一个工具类。
对应的提示词如下：
使用JDK8生成下面的四个方法，并提供main函数进行自测：
1）根据给定日期，返回当月的第一天和最后一天的日期，出参使用日期数组。
2）根据给定日期，返回去年当月的第一天和最后一天的日期，出参使用日期数组。
3）根据给定日期，返回当年的第一天和最后一天的日期，出参使用日期数组。
4）根据给定日期，返回去年的第一天和最后一天的日期，出参使用日期数组。1）DeepSeek-Coder-33B-Instruct生成的代码：
package ai.deepseek;
import java.time.LocalDate;
import java.time.YearMonth;
import java.time.temporal.TemporalAdjusters;
public class DateUtils {
public static LocalDate[] getCurrentMonthStartAndEnd(LocalDate date) {
YearMonth yearMonth = YearMonth.from(date);
LocalDate firstDayOfMonth = yearMonth.atDay(1);
LocalDate lastDayOfMonth = yearMonth.atEndOfMonth();
return new LocalDate[]{firstDayOfMonth, lastDayOfMonth};
}
public static LocalDate[] getLastYearSameMonthStartAndEnd(LocalDate date) {
LocalDate lastYearDate = date.minusYears(1);
return getCurrentMonthStartAndEnd(lastYearDate);
}
public static LocalDate[] getCurrentYearStartAndEnd(LocalDate date) {
LocalDate firstDayOfYear = date.with(TemporalAdjusters.firstDayOfYear());
LocalDate lastDayOfYear = date.with(TemporalAdjusters.lastDayOfYear());
return new LocalDate[]{firstDayOfYear, lastDayOfYear};
}
public static LocalDate[] getLastYearStartAndEnd(LocalDate date) {
LocalDate lastYearDate = date.minusYears(1);
return getCurrentYearStartAndEnd(lastYearDate);
}
public static void main(String[] args) {
LocalDate currentDate = LocalDate.now();
LocalDate[] currentMonthDates = getCurrentMonthStartAndEnd(currentDate);
System.out.println("Current month start: " + currentMonthDates[0]);
System.out.println("Current month end: " + currentMonthDates[1]);
LocalDate[] lastYearSameMonthDates = getLastYearSameMonthStartAndEnd(currentDate);
System.out.println("Last year same month start: " + lastYearSameMonthDates[0]);
System.out.println("Last year same month end: " + lastYearSameMonthDates[1]);
LocalDate[] currentYearDates = getCurrentYearStartAndEnd(currentDate);
System.out.println("Current year start: " + currentYearDates[0]);
System.out.println("Current year end: " + currentYearDates[1]);
LocalDate[] lastYearDates = getLastYearStartAndEnd(currentDate);
System.out.println("Last year start: " + lastYearDates[0]);
System.out.println("Last year end: " + lastYearDates[1]);
}
}运行的结果正确。
Current month start: 2024-02-01
Current month end: 2024-02-29
Last year same month start: 2023-02-01
Last year same month end: 2023-02-28
Current year start: 2024-01-01
Current year end: 2024-12-31
Last year start: 2023-01-01
Last year end: 2023-12-31测评分析：
加分项：生成的代码能正确编译；运行结果正确；在原方法基础上提炼出了可复用的方法；
减分项：方法命名有点中国式英文的风格，不够优雅；代码没有注释；
评分：80分。

2、测评二：报表数据填充代码生成
测评二也是来源于实际工作中的一个需求场景。报表数据的填充补全，入参是只有部分日期的当月报表数据，需要补充当月其它日期的数据记录，输出完整的当月数据记录。
对应的提示词如下：
有一个对象列表，List<TendencyChartVO>，TendencyChartVO对象有两个字段:dt,name, 其中有一个dt字段，为日期类型。name为String类型。
对象列表里可能只有当月其中几天的数据。帮我写一个函数，填充当月剩余的日期数据，只填充dt字段值就可以，填充好以后对List<TendencyChartVO>按日期排序。同时提供main函数进行自测。1）DeepSeek-Coder-33B-Instruct

3、测评三：代码补全
测评三是需要实现一个字符串数据处理方法，根据注释里的实现步骤，进行代码补全。
提示词如下：
你是一个优秀的java开发工程师，致力于写出高质量的代码。现在给你一个代码类，根据代码骨架和注释补全生成完整的代码。
要求：
1.保证代码的准确性，可读性，可维护性；
2.使用子函数封装，每个方法尽量不超过50行；
3.在驼峰格式转成下划线格式的方法中，打印出转成下划线格式后的那个值；
4.包括main函数，可以进行自测；
public class Transformer {
public String transform(String source) {
//1.对source实现对驼峰格式转成下划线格式的功能
//2.再进行MD5摘要
//3.最后加上当前时间戳，以$符号连接。

5、测评五：代码纠错
日常开发中经常会碰到，需要寻找或者检查一段代码中的是否有bug的情况。测评五是比对两个同类型对象是否相同的代码，其中”StringUtils.isEmpty(that.storeId)?null:this.storeId)”这句存在bug。
提示词如下：
帮我查找这段代码中的bug，给出完整的类并包括main函数，可以进行自测对象为空的情况:
@Override
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (!(o instanceof SkuKey)) {
return false;
}
SkuKey that = (SkuKey) o;
return new EqualsBuilder()
.append(skuId, that.skuId)
.append(StringUtils.isEmpty(storeId)?null:storeId, StringUtils.isEmpty(that.storeId)?null:this.storeId)
.isEquals();

四、总结
| 大模型 | 日期工具类 | 报表数据填充 | 代码补全 | 代码优化 | 代码纠错 | 单元测试 | 平均分 |
| DeepSeek-Coder-33B | 80分 | 50分 | 85分 | 85分 | 80分 | 90分 | 78.3分 |
| CodeLlama-70B | 60分 | 80分 | 60分 | 80分 | 50分 | 76分 | 67.7分 |
| GLM-4 | 90分 | 85分 | 60分 | 80分 | 60分 | 80分 | 75.8分 |
| GPT-3.5 | 90分 | 50分 | 80分 | 85分 | 80分 | 76分 | 76.8分 |
| GPT-4 | 85分 | 85分 | 90分 | 90分 | 100分 | 88分 | 89.7分 |
可以看到，在Java编码能力方面，GPT-4-0613 > DeepSeek-Coder-33B-Instruct > GPT-3.5 > GLM-4 > CodeLlama-70B-Instruct。整体来看，GPT-4在六项测评中都表现得比较稳定，其它四个大模型都存在在某项测评中表现不太稳定的情况。在编码大模型的选型方面，如果追求性能，首选还是GPT-4，但是也比较贵。如果从安全性和性价比考虑的话，私有化部署开源编码大模型DeepSeek-Coder-33B-Instruct应该是一个不错的选择。DeepSeek-Coder-33B-Instruct、GPT-3.5、GLM-4这三个大模型编码能力比较接近，相差不大。至于CodeLlama-70B-Instruct，还是有点差距（小扎加油！）。从本次测评生成的具体代码可以看出，在给出某个功能比较明确的需求设计说明，类似我们写某个功能模块的详细设计这类的文档之后，代码大模型大部分情况可以快速实现这个功能需求。虽然实现的不一定好，在代码的可复用性、可读性、可扩展性方面还有所欠缺，但大部分也能达到初级程序员的水平，在算法优化方面甚至能达到中高级程序员水平。在实际使用过程中，可以通过代码大模型来加快程序的开发。之前需要程序员完全自己实现代码，现在可以先让大模型输出第一版，完成80%的代码，在这个基础上再去完善，提升研发效率。
以上通过代码生成、代码补全、代码优化、代码纠错、单元测试这几个方面，共6个测评案例，对大模型在Java编码能力进行了测评分析。汇总出测评的得分表如下。
