Agent Plan
一站式智能体开发方案，快速搭建专属 AI Agent
1 获取并配置 API Key
- 获取 API Key：在控制台左下角切换到目标项目，在左侧导航中选择 API Key 管理，创建或获取方舟 API Key。
- 配置环境变量：在终端中运行下面命令（替换your_api_key_here 为你的方舟API Key），配置 API Key 到环境变量。
export ARK_API_KEY="your_api_key_here"
export ARK_API_KEY="your_api_key_here"
setx ARK_API_KEY "your_api_key_here"
$env:ARK_API_KEY = "your_api_key_here"
2 开通模型服务
3 安装 SDK
安装方舟官方 SDK 或第三方 SDK。
- 安装方舟官方 SDK：
- python -m pip install --upgrade arkruntime
- 安装 OpenAI SDK：
- pip install openai
运行以下命令安装方舟官方 Go SDK：
go get github.com/volcengine/ark-runtime-go@latest
在代码中引入：
import "github.com/volcengine/ark-runtime-go/arkruntime"
在项目的pom.xml文件中添加以下依赖配置。
<dependency>
<groupId>com.volcengine</groupId>
<artifactId>ark-runtime</artifactId>
<version><VERSION></version>
</dependency>

4 发起 API 请求
以下按输入输出类别列举的典型任务，选择任意示例代码体验如何通过 API 调用及体验大模型及方舟平台能力。
文本生成
传入文本类信息给模型，进行问答、分析、改写、摘要、编程、翻译等任务，并返回文本结果。

5 下一步
现在你已经完成了首次方舟模型服务的 API 调用，你可以探索模型的更多能力，包括：
- 模型列表：快速浏览方舟提供的模型全集以及各个模型所具备的能力，快速根据你的实际场景匹配到合适的模型。
- 模型接入指南（LLM） - 标准流程：把方舟大模型接入生产环境的完整流程（参数配置、Harness 接入、突发流量爬坡、上线监控）。
- 模型接入指南（LLM） - 常见问题：接入 / 上线过程中的效果、可用性、接入配置、选型常见问题。
- 模型接入指南（LLM） - 性能评测：上线前跑一次性能基线评测（TTFT / TPOT / E2E / 缓存命中率）。
