Use QwenCloud models in VS Code.

Quick Start

1

Get an API key

Get the API key for your billing plan:
2

Open model management

In VS Code, run Chat: Manage Language Models, select Add Models > Custom Endpoint, and select Chat Completions as the protocol.
3

Enter the connection details

Follow the wizard to enter a group name, display name, and the API key for your plan. The wizard generates a secure input reference for apiKey; do not put the actual key in plaintext JSON.
4

Select a model

Enter the connection URL and model for your billing plan:
  • Token Plan
  • Pay-as-you-go
  • Base URL: https://token-plan.maas.qwencloudapi.com/compatible-mode/v1
  • Full url: https://token-plan.maas.qwencloudapi.com/compatible-mode/v1/chat/completions
  • Models: Enter a text generation model supported by Individual or Team Edition

Configure model parameters

In chatLanguageModels.json, configure the following fields:
  • vendor: customendpoint
  • apiType: chat-completions
  • models[].id: The model ID from the previous step
  • models[].name: A display name of your choice
  • models[].url: The full url from the previous step
  • models[].toolCalling, vision, maxInputTokens, maxOutputTokens: Set these according to the model's specifications
Confirm that your plan supports the model, then check the model list. The sum of input and output tokens must not exceed the model's context length. For field descriptions, see the VS Code official documentation.

Verify

Select the configured model in the Chat model picker and send "Hello". A reply confirms the connection.

FAQ

Save chatLanguageModels.json, restart VS Code, and check the model picker again.
Confirm that the API key, Base URL, and model belong to the same plan. Token Plan and pay-as-you-go API keys are not interchangeable. For pay-as-you-go, also confirm that the API key is from the same region as the Base URL.
Ask your Copilot Business / Enterprise administrator to check the Bring Your Own Language Model Key in VS Code policy.
