Documentation
Quick Start
1. Install Extension
Install from the VS Code Extension Marketplace.
Press Ctrl+Shift+P (macOS: Cmd+Shift+P), run Copilot Models: Set API Key,
select a provider and enter your key.
Note: API keys are stored in VS Code SecretStorage, not as plain settings.
If you use prepaid token packages (e.g., Alibaba DashScope plan),
run Copilot Models: Set Token Plan to configure plan access:
- Press
Ctrl+Shift+P (macOS: Cmd+Shift+P), run Copilot Models: Set Token Plan
- Select a built-in provider preset or enter a custom URL
- The Qwen preset is preconfigured with the endpoint URL and 9 supported models
- Enter the plan API token
- Select the models covered by this plan
The plan token is saved in VS Code SecretStorage.
- Qwen Token Plan —
https://token-plan.cn-beijing.maas.aliyuncs.com/compatible-mode/v1
The Qwen Token Plan preset covers Qwen, DeepSeek, and GLM models
in a single plan.
For other providers, choose "Custom URL" and enter the plan API endpoint.
Run Copilot Models: Clear Token Plan to remove a configured plan.
If you want to use image attachments with models that don't natively support
image input (e.g., GLM-5 series, Qwen3.7 Max), configure a vision proxy to
automatically convert images to text descriptions:
- Press
Ctrl+Shift+P (macOS: Cmd+Shift+P), run
Copilot Models: Set Vision Model
- Select a vision-capable model, or choose "Custom API Endpoint"
- For custom API endpoint, enter the URL and model ID
The vision proxy describes images before sending them to the chat model.
For custom API endpoints, an OpenAI-compatible /chat/completions endpoint is required.
Run Copilot Models: Clear Vision Model to remove the configuration.
5. Start Using
- Open GitHub Copilot Chat panel
- Click on the model selector
- Select the model to use
- Start chatting

Token Plan Coverage
The built-in Qwen Token Plan preset supports the following models through
a single unified endpoint:
| Model |
ID |
| Qwen3.7 Max |
qwen3.7-max |
| Qwen3.7 Plus |
qwen3.7-plus |
| Qwen3.6 Flash |
qwen3.6-flash |
| Qwen3.6 Plus |
qwen3.6-plus |
| GLM-5.2 |
glm-5.2 |
| GLM-5.1 |
glm-5.1 |
| GLM-5 |
glm-5 |
| DeepSeek V4 Pro |
deepseek-v4-pro |
| DeepSeek V4 Flash |
deepseek-v4-flash |
Models not listed (e.g. Qwen3 Max, GLM-5-Turbo) are still available via direct
provider API access — they are simply not covered by this Token Plan preset.

Note: The maxTokens config has been removed. Each model now
automatically uses its own maxOutputTokens as the API's max_tokens
parameter — no manual configuration needed. See the "Output" column in
the Supported Models tables above.

Debugging
If you encounter issues, check the logs:
- Press
Ctrl+Shift+P, run Copilot Models: Show Log
- Logs appear in the "Copilot Models" output panel
- Set
debugMode to verbose for detailed debug output
- Set to
minimal (default) for warnings and errors only
Log level changes take effect immediately without reloading the extension.
Each request's logs carry a structured prefix
(req=<id> provider=<id> model=<id>), so you can grep for a single req=<id>
to trace one request across routing, provider, and network layers.
API keys, tokens, and URL query strings are automatically redacted from the
logs — secrets never appear in the output panel.
