DeepSeek V4: Free, Unlimited, and Ready to Use

This guide walks through subscribing to the DeepSeek V4 plan, creating a deepseek-v4 token, syncing the model in CC Switch, and verifying it in Claude Code or VS Code.

Core point: to use DeepSeek V4 successfully, the plan, token group, and CC Switch model sync all have to match the deepseek-v4 group.

1. Sign in and open Wallet

2. Subscribe to the DeepSeek V4 plan

Open the subscription tab in Wallet, locate the DeepSeek V4 plan, and confirm the plan name before paying.

Before payment, double-check that the page really shows the DeepSeek V4 plan. Using the wrong plan will break the later token mapping.

After payment, return to the plan page and make sure the subscription is active.

3. Create a deepseek-v4 token

Go to token management and create a new API key. The token group must be deepseek-v4.

4. Copy the Base URL and API key

These two values are what CC Switch needs for the gateway connection.

5. Add the provider in CC Switch

Create a unified provider in CC Switch and enter the Base URL and API key you just prepared.

Sync the model list

Run model sync and make sure models such as deepseek-v4-pro or deepseek-v4-flash appear in the list.

6. Verify in Claude Code

Launch Claude Code in the terminal and send a simple request to confirm that calls go through correctly.

7. Verify in VS Code

If you also use VS Code, confirm that the extension is reading the same provider configuration and not an old endpoint.

8. Check usage logs and balance

After the connection works, check the usage log and balance view to make sure the request path and billing group look correct.
