How to Deploy Qwen 3.5‑Plus with CoPaw on Alibaba Cloud ACK/ACS via Agent Sandbox

Background

Qwen 3.5, released by Alibaba in February 2026, is a large‑parameter model that uses a gated‑delta architecture to achieve high performance with only ~5% active compute. CoPaw, an open‑source personal AI assistant built on the AgentScope framework, can be integrated with Qwen 3.5 to provide web‑search, data‑collection, and report‑generation capabilities.

Prerequisites

Create an ACK Pro or ACS cluster that has access to ACS computing power.

Install the kubectl command‑line tool (see the official Kubernetes docs).

When creating the cluster, enable the “Expose API server with EIP” option to allow public access.

Install ACS Agent Sandbox Components

Install the ACK Virtual Node component (skip for ACS clusters).

Install the ack-agent-sandbox-controller component, version >= v0.5.3.

Create the CoPaw Sandbox

Download the temporary KubeConfig from the cluster console and save it to ~/.kube/config (or the Windows equivalent). Then create a copaw.yaml file with the following content:

apiVersion: agents.kruise.io/v1alpha1
kind: Sandbox
metadata:
  labels:
    app: copaw
  name: copaw
  namespace: default
spec:
  template:
    metadata:
      labels:
        alibabacloud.com/acs: "true"
        app: copaw
    spec:
      containers:
      - image: agentscope-registry.ap-southeast-1.cr.aliyuncs.com/agentscope/copaw:latest
        imagePullPolicy: IfNotPresent
        command: ["copaw", "app"]
        name: copaw
        ports:
        - containerPort: 8088
        resources:
          limits:
            cpu: "2"
            memory: 4Gi
          requests:
            cpu: "2"
            memory: 4Gi

Apply the manifest:

$ kubectl create -f copaw.yaml
sandbox.agents.kruise.io/copaw created

After creation, a Pod named copaw will start and the service becomes reachable.

Configure CoPaw

Port‑forward the service so the local browser can reach it:

$ kubectl port-forward copaw 8088:8088
Forwarding from 127.0.0.1:8088 -> 8088
Forwarding from [::1]:8088 -> 8088

Obtain an API‑Key from the Alibaba Cloud Bailei model service platform (Model Marketplace → API‑Key Management).

Open http://127.0.0.1:8088/models and paste the API‑Key.

Select the desired model ID (e.g., qwen3.5-plus) from the Bailei model list.

Integrate with DingTalk

Follow the DingTalk Open Platform documentation to create an internal application, add the “Robot” capability, and set the message reception mode to “Stream”. After publishing the app, retrieve the AppKey (Client ID) and AppSecret (Client Secret).

In CoPaw’s channel management page ( http://127.0.0.1:8088/channels), add a DingTalk channel and fill in the obtained credentials.

Using CoPaw

Search for the robot name (e.g., rbg-copaw) in DingTalk, start a conversation, and interact with the assistant.

Optional: Sandbox Pause‑and‑Wake

To save resources when CoPaw is idle, edit the sandbox CR to set spec.paused: true. The sandbox will enter a paused state, the Pod disappears, and only minimal storage costs remain.

$ kubectl edit sandbox copaw  # set spec.paused to true

Resume the sandbox by setting spec.paused: false and applying the change.

$ kubectl edit sandbox copaw  # set spec.paused to false

After resuming, the sandbox status returns to Running and the Pod is recreated.

Conclusion

Alibaba Cloud ACK combined with the ACS Agent Sandbox provides a ready‑to‑use, secure, and elastic infrastructure for AI agents like CoPaw, enabling rapid deployment, on‑demand scaling, and seamless integration with messaging platforms.
