Security Control

Before calling Model Studio, select a region and a service deployment scope:

  • Region: Determines the access point and data storage location. Choose a nearby region to reduce latency.

  • Service deployment scope: Determines the inference execution location. If you have data residency requirements, select a scope with specific geographic boundaries. Otherwise, select the Global scope for a larger inference resource pool.

A complete model invocation works as follows:

  1. Your application sends a request to the selected region (such as Singapore) through the Base URL. Request data is stored in that region.

  2. The region forwards the request to an inference node within the service deployment scope (transient data is not persisted; all transmissions are encrypted).

  3. The inference result is returned to the region for storage and then sent back to your application. Your static data always remains in the selected region.

Select region and service scope

Choose a region and service deployment scope based on your scenario:

Regional access information

Each region has its own Base URL, API Key, and model list. These cannot be used across regions.

Important

Model Studio has released new domain names for China (Beijing), Singapore, and China (Hong Kong) regions: {WorkspaceId}.{region}.maas.aliyuncs.com. {WorkspaceId} is the workspace ID (available from the Workspace Management page of each region), and {region} can be cn-beijing, ap-southeast-1, or cn-hongkong. The following legacy domains will be deprecated soon. Please migrate as soon as possible:

  • China (Beijing): Please migrate from dashscope.aliyuncs.com to {WorkspaceId}.cn-beijing.maas.aliyuncs.com

  • Singapore: Please migrate from dashscope-intl.aliyuncs.com to {WorkspaceId}.ap-southeast-1.maas.aliyuncs.com

  • China (Hong Kong): Please migrate from cn-hongkong.dashscope.aliyuncs.com to {WorkspaceId}.cn-hongkong.maas.aliyuncs.com

Singapore

  • Base URL (OpenAI compatible): https://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com/compatible-mode/v1. When calling, replace WorkspaceId with your actual workspace ID.

  • Base URL (Anthropic compatible): https://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com/apps/anthropic

  • Base URL (DashScope): https://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com/api/v1

  • API Key: Key Management (Singapore)

  • Model list: Available Models (Singapore)

China (Beijing)

  • Base URL (OpenAI compatible): https://{WorkspaceId}.cn-beijing.maas.aliyuncs.com/compatible-mode/v1. When calling, replace WorkspaceId with your actual workspace ID.

  • API Key: Key Management (Beijing)

  • Model list: Available Models (Beijing)

China (Hong Kong)

Hong Kong uses workspaces to separate service deployment scopes. API Keys are isolated between workspaces. Before making API calls, create a workspace:

  1. Go to Workspace Management (Hong Kong) and create a workspace. Select a service deployment scope (Global or Hong Kong).

  2. Get the Workspace ID (Hong Kong) and replace {WorkspaceId} in the Base URLs below.

  • Base URL (OpenAI compatible): https://{WorkspaceId}.cn-hongkong.maas.aliyuncs.com/compatible-mode/v1

  • Base URL (Anthropic compatible): https://{WorkspaceId}.cn-hongkong.maas.aliyuncs.com/apps/anthropic

  • Base URL (DashScope): https://{WorkspaceId}.cn-hongkong.maas.aliyuncs.com/api/v1

  • API Key: Key Management (Hong Kong)

  • Base URL (DashScope): https://dashscope-us.aliyuncs.com/api/v1

  • API Key: Key Management (Virginia)

  • Model list: Available Models (Virginia)

US-only inference: Use model names with the -us suffix, such as qwen-plus-us. Without the suffix, inference defaults to the Global scope.

Germany (Frankfurt)

Frankfurt uses Workspaces to separate deployment scopes. API Keys are isolated between workspaces. Before making API calls, create a workspace:

  1. Go to Workspace Management (Frankfurt) and create a workspace. Select a service deployment scope (Global or EU).

  2. Get the Workspace ID (Frankfurt) and replace {WorkspaceId} in the Base URLs below.

  • Base URL (OpenAI compatible): https://{WorkspaceId}.eu-central-1.maas.aliyuncs.com/compatible-mode/v1

  • Base URL (Anthropic compatible): https://{WorkspaceId}.eu-central-1.maas.aliyuncs.com/apps/anthropic
