Platform For AI:Platform for AI (PAI) system policy reference

Last Updated:Apr 01, 2026

Lists all system policies that PAI supports, with the permissions each policy grants to RAM identities.

What is a system policy

An access policy is a collection of permissions described in a specific syntax. It defines the authorized resources, actions, and conditions. Resource Access Management (RAM) provides two types of access policies:

  • System policies: Created and maintained by Alibaba Cloud. Use them without modification.

  • Custom policies: Created, updated, and deleted by you to fit specific requirements.

As PAI evolves, new permissions are added to system policies to support new features. These updates apply automatically to all RAM identities—RAM users, RAM user groups, and RAM roles—that have been granted the policies.

System policies fall into three categories: product system policies, service role policies, and service-linked role policies. Not all categories apply to every product. The available types for PAI are listed in this topic.

For a full overview of RAM access policies, see Overview of access policies.

Note

System policies enable quick start and apply to console access, OpenAPI, and command-line interface (CLI) access. However, for better data security, use custom policies for OpenAPI or CLI access to grant only the specific permissions that each user or application requires.

Service-linked role policies

Service-linked role policies are attached exclusively to service-linked roles. Do not attach them to RAM users, RAM user groups, or RAM roles.

AliyunServiceRolePolicyForPaiLangStudio

PAI uses the service-linked role AliyunServiceRoleForPaiLangStudio to access resources in other Alibaba Cloud services. AliyunServiceRolePolicyForPaiLangStudio is the authorization policy for that role. This policy is defined and managed by PAI—it cannot be modified or deleted.

AliyunServiceRolePolicyForPAIABTest

PAIABTest uses the service-linked role AliyunServiceRoleForPAIABTest to access resources in other Alibaba Cloud services. AliyunServiceRolePolicyForPAIABTest is the authorization policy for that role. This policy is defined and managed by PAIABTest—it cannot be modified or deleted.

Authorization reference

By default, RAM identities have no permissions. An Alibaba Cloud account administrator must grant permissions before a RAM identity can access account resources.

To grant permissions to a RAM identity, see the relevant guide:
