Security Control

Manually managing message lists for conversations that span multiple devices or have long interruptions can lead to context loss. Alibaba Cloud Model Studio provides an OpenAI-compatible Conversations API that you can use with the Responses API to automatically inject historical context. This eliminates the need for manual message synchronization and ensures conversational continuity across different scenarios and devices.

Create conversation

Creates a new conversation. You can optionally include initial message items.

North China 2 (Beijing): POSThttps://dashscope.aliyuncs.com/compatible-mode/v1/conversations

Singapore: POSThttps://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com/compatible-mode/v1/conversations

Important

The legacy URL path /api/v2/apps/protocols/compatible-mode/v1/responses will soon be deprecated. Migrate to the new path /compatible-mode/v1/responses as soon as possible.

Important

The legacy Singapore domain https://dashscope-intl.aliyuncs.com will be discontinued. Migrate to https://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com as soon as possible.
