一、百度智能云开发者注册

1、实名认证

进入百度智能云 https://cloud.baidu.com/ 网站 , 登录百度账号后 , 首先要进行实名认证 , 使用微信扫码即可进行刷脸认证 , 之后才能开通大模型服务 ;

实名认证完成后 , 将鼠标移动到右上角用户名下方 , 会显示 " 实名认证用户 " ;

2、开通模型服务

回到百度智能云 https://cloud.baidu.com/ 首页 , 点击界面中间的 " 立即体验 " 按钮 ;

进入千帆ModelBuilder 页面 https://console.bce.baidu.com/qianfan/overview , 此时在页面顶部提示 " 您尚未开通模型服务，开通后可通过体验中心或调用API使用预置模型服务。 " , 点击右侧的 " 立即开通 " 按钮 , 开通模型服务 ;

在弹出的对话框中 , 点击 " 确认开通 " 按钮 , 开通模型服务 ;

成功开通 , 会有如下提示 ;

二、开发文档和视频教程

初次接触百度千帆大模型 , 可以参考官方提供的文档和视频教程了解大模型使用 ;

1、视频教程

百度智能云课程中心 : https://cloud.baidu.com/partner/course-center/index.html

选择 " 百度智能云千帆AI加速器 / 百度智能云千帆ModelBuilder / 对话chat_API调用 " 在页面中会刷新符合筛选条件的课程 , 对话chat_API调用课程页面

2、开发文档

文档首页 : 百度智能云千帆大模型服务与开发平台ModelBuilder

参考平台使用指引 https://cloud.baidu.com/doc/WENXINWORKSHOP/s/7ltgucw50 逐步了解百度智能云千帆ModelBuilder 的功能 ;

三、模型广场

在模型广场 https://console.bce.baidu.com/qianfan/modelcenter/model/buildIn/list 中 , 可以看到百度提供的 68 个大模型 ,

四、体验中心

在体验中心 https://console.bce.baidu.com/qianfan/ais/console/onlineTest/LLM 可以体验各种大模型 ;

目前可以白嫖体验 DeepSeek R1 模型 , 过几天开始收费了 , 不过费用很便宜 ;

五、在线推理

在在线推理 https://console.bce.baidu.com/qianfan/ais/console/onlineService 页面可以查看各种大模型的付费状态 , 操作 ;

大部分模型都是默认按量后付费 , 一旦使用就会产生费用 , 注意不要乱用 ;

六、Python SDK 简单调用

1、参考文档

参考文档 Python SDK调用对话Chat V1教程 ;

2、开发环境准备

首先安装 Python 环境和 PyCharm 开发工具 :

【开发环境】Windows 中安装 Python 各个版本 ( 下载 Python 各版本 SDK | 安装 Python )

【开发环境】Windows 安装 PyCharm 开发环境 ( 下载 PyCharm | 安装 PyCharm | 在 PyCharm 中创建 Python 工程 )

执行

Python -V

命令 , 查看 Python 版本 , 需要保证 Python 版本大于等于 3.7 版本 ; 执行结果如下 :

C:\Users\octop>Python -V
Python 3.7.9

3、安装 SDK

运行

pip install qianfan

命令 , 安装千帆ModelBuilder SDK ; 执行结果如下 :

C:\Users\octop>pip install qianfan

4、拷贝示例代码

拷贝示例代码到 PyCharm 中 , 下面的代码中必须到百度智能云安全认证界面找到自己的 Access Key 和 Secret Key 替换到代码中 ;

import os
import qianfan

# 通过环境变量初始化认证信息
# 方式一：【推荐】使用安全认证AK/SK
# 替换下列示例中参数，安全认证Access Key替换your_iam_ak，Secret Key替换your_iam_sk，如何获取请查看https://cloud.baidu.com/doc/Reference/s/9jwvz2egb
os.environ["QIANFAN_ACCESS_KEY"] = "your_iam_ak"
os.environ["QIANFAN_SECRET_KEY"] = "your_iam_sk"

# 方式二：【不推荐】使用应用AK/SK鉴权
# 替换下列示例中参数，将应用API_Key、应用Secret key值替换为真实值
#os.environ["QIANFAN_AK"] = "应用API_Key"
#os.environ["QIANFAN_SK"] = "应用Secret_Key"

chat_comp = qianfan.ChatCompletion()

# 指定特定模型
resp = chat_comp.do(model="ERNIE-3.5-8K", messages=[{
    "role": "user",
    "content": "你好"
}])

print(resp["body"])

5、查找 Access Key 和 Secret Key

参考如何获取AKSK 页面获取 SK 和 AK ;

到百度智能云安全认证页面 https://console.bce.baidu.com/iam/#/iam/accesslist 的 Access Key 面板中 , 查找 AK 和 SK ;

下面的页面中 , 蓝色矩形框中的是 Access Key , 红色矩形框中是 Secret Key ;

SK 查看需要进行手机验证码验证 , 验证完毕后 , 即可查看 SK ;

将上面查找到的 AK 和 SK 替换到下面的字符串中 ;

os.environ["QIANFAN_ACCESS_KEY"] = "your_iam_ak"
os.environ["QIANFAN_SECRET_KEY"] = "your_iam_sk"

6、执行结果

执行 Python 代码 , 得到如下结果 :
