Kiro应用评测

Kiro 是一个由亚马逊推出的 AI 驱动的智能开发环境，从原型到生产全程陪伴您的开发过程。它将"灵感编程"的流畅性与规范的清晰性相结合，帮助您更快地构建更好的软件。

昨天收到了Kiro的试用邮件，收到邮件后第一时间下载了Kiro并试用了一下，效果还不错，并根据日常能用到的功能进行了测试。

本次测试将以日常项目开发为基础，从一下几个方面进行应用测试：

英文识别率
中文识别率
图片设计的转化率
首次代码生成能力
修改代码生成能力
复杂逻辑生成能力
生成速度
费用

测试前的准备

下载并安装Kiro，从邮件上直接点击Download就可以到Kiro的下载页面，并下载安装。
第一次打开Kiro需要登陆，我这里使用github账号登陆。登陆成功后需要输入邀请码，完成这些步骤后就可以开始使用了。
打开后的Kiro界面是这样的。和vscode、Trae风格差不多，紫色系。

Kiro提供了2中开发模式，分别是Vibe和Spec。简单来说就是简单任务用Vibe，复杂任务用Spec。我们来看看Kiro帮助文档是如何推荐我们使用的。

何时使用 Vibe

交互式问答格式：Vibe 会话针对代码的来回对话进行了优化，允许您提出问题并获得即时响应。
快速帮助：它们非常适合快速回答编码问题、解释代码行为或理解概念，而无需经过正式的规范过程。
上下文理解：与其他 Kiro 会话一样，Vibe 会话利用上下文提供者来理解您的代码库，但重点是解释而不是大量代码生成。
灵活的方法：与 Spec 会话相比，Vibe 会话提供了更流畅、更少结构化的方法，使其适合探索性编码和学习。

何时使用 Spec

复杂的开发任务：对于构建复杂功能、整个应用程序或需要仔细规划和执行的重大重构，请使用 Spec 会话。
结构化方法：当您需要一种有条理的、循序渐进的开发方法，并清楚记录需求和实施细节时。
团队协作：对于多个团队成员需要理解实施计划并根据规范跟踪进度的项目。
文档需求：当您希望在代码实施的同时生成详细文档，以供将来参考或知识共享时。

Spec是Kiro的特色，它完全模仿我们日常开发的流程，从用户故事⇒需求说明⇒系统设计⇒任务开发⇒测试上线。

测试过程

整个测试过程我们会创建一个Web应用，模拟太阳系的运行，实现3D可拖拽的展示风格。

首次代码生成能力

我们输入下面的Prompt，等待一会儿就可以得到输出。

`Create a web application, simulate the solar system.`

可以看到，这里使用了Claude Sonnet 4.0版本，自动生成了三个文件

index.html
script.js
styles.css

我看了一下生成的代码，和人工写的区别不大，在后期运维和修改还是可行的。

我们希望把生成的项目运行起来，我们继续输入

`launch the web site.`

Kiro自动识别了运行网站的需求，并等到我确认是否执行命令。我们点击运行，会自动打开浏览器
请添加图片描述
第一个版本已经可以成功运行了，我们其实就只输入了一个想法，Kiro就自动生成了一个完整的网站，并且展示效果和我们期望的出入不大，从这点来看效果还是很不错的。并且细节部分也考虑的很周到，可以看到行星的轨道，月球也生成出来了，并且可以看到月球绕地球旋转的轨道。另外如果注意看，地球还用了渐变色，蓝绿色的渐变。太阳自带了光晕效果。

修改代码生成能力

代码修改能力主要考验AI是不是能以现有代码为基础，根据我们进一步的需求，修改代码以实现我们的要求。我们让Kiro将网站改为三维的宇宙，可以通过鼠标拖动界面，支持缩放。

输入以下提示词

`Make the web view as 3D, the view can be dragged in 3d.`

这次需要等待一会儿，大概5分钟左右就会完成。看了一下用量，大概每个需求的调整的Vibe的用量大概在2-3。

展示效果还是不错的，实现了页面的三维拖动、放大缩小效果。
请添加图片描述
2. 进一步调整页面布局。

`Make the web view full screen, move controls and instructions to upper right without background.`

这次调整是想页面全屏展示，将下方的操作按钮放到页面的右上角，并且不要有黑色的背景。

复杂逻辑生成能力

复杂逻辑的生成能力使用Spec模式，输入一个完整的需求文档，让大模型根据需求文档来修改代码。

下面就是输入的需求文档，这个文档使用豆包根据我的需求生成的。主要的需求是“通过点击地球，可以放大地球，需要详细描绘地球的细节，同时生成地球周围的卫星、航天飞机”

Spec会按照Requirements、Design、TaskList的顺序执行。

Requirements

Design

Task List

点击每个Task上的Start task，下面是最终完成的效果。这里没有全部走完，运行了4个task，实现了地球的选中和显示，星球的自转等功能。
请添加图片描述

在测试的时候我是等每个Task执行完成后再点下一个Task上的Start
Task的，我也是在想这个就不能批量执行吗，难道要一直看着吗。后来无意中连续点了多个Start
Task才发现，是可以点多个的，后面的几个Task会加入到执行队列，依次执行。

中文识别率

之前一直使用的是使用英文的提示词，这里我们试一下使用中文提示词是否也是一样的效果。这里尝试直接输入中文提示词，测试生成代码的情况。

`增加随机流星的效果`

从测试效果来看，以中文格式输入，无论Vibe还是Spec模式，模型的输出都会切换为中文，这点还是很友善的。第一次尝试用中文输入，生成的结果是定位到了一个test页面，关闭再重新来一次打开才正常。相比来说应该采用英文是更合适的，模型能够理解的更好。中文是不是偶然的情况还是需要多尝试。

根据图片生成页面

输入下面这张驾驶舱图片

几轮Task执行下来的效果，对比下来出入还是挺大的。

费用

最近测试阶段，Vibe和Spec都赠送了100点。另外免费用户，每个月赠送50点的Vibe用量，无法使用Spec功能。

收费用户的话PRO是每个月20美元，PRO+是40美元，区别应该都是点数不同。另外超过额度的 0.04美元/vibe，0.20美元/spec。

根据这次测试的用量大概估算了一下：
每次vibe交互，使用2-3个vibe点数；每次执行spec的task，会消耗1个spec，同时也会消耗4-5个vibe点数，所以累加起来，每个spec task大概是0.30-0.50美元不等，一般spec会在十多个，按10个算的话，一次完整的spec代码生成的费用大概在3-5美元。

总结

Kiro给我的使用体验还是不错的，主要是将开放式的操作和流程式的引导融合到了一起，将日常项目开发的项目管理过程引入了软件中，功能沟通、需求说明书生成、系统设计、任务拆分、任务执行，最终实现一次功能迭代。但是也有写不足的地方，首先是Kiro主要是以spec形式的代码生成为主，所以没有代码辅助功能，特别是有些代码希望手工调整的时候，无法得到AI的辅助。

还有点个人的体验说明，看了一下Kiro生成的文档和代码，整体感觉上比较啰嗦，或者说考虑的比较周到，面面俱全。特别是Spec模式，每次一的Spec执行他都会认为是一次完整的程序生成，包括测试、打包、部署。
