How the integration works
Cline exposes the required settings directly in its provider UI. Choose OpenAI Compatible, paste a DeepSeek-V4.io key, set the base URL, and enter the public model id.
Create and manage it on /developer.
The client talks to its native compatible endpoint.
Provider credentials and routing stay on the server.
Before you start
- Cline installed in VS Code or a compatible editor
- A paid DeepSeek-V4.io account with an API key from /developer
- Access to the Cline API Provider settings
Configure Cline
API Provider: OpenAI Compatible
Base URL: https://deepseek-v4.io/api/v1
API Key: your-deepseek-v4-io-key
Model ID: deepseek-v4-flashVerify the setup
The page remains Experimental until these checks pass against the public DeepSeek-V4.io gateway.
- 1Start a new Cline task after saving the provider settings.
- 2Ask Cline to read one file without applying a change.
- 3Confirm streaming and a read-only tool call both complete.
Troubleshooting
Cline reports an invalid URL
Use the full base URL https://deepseek-v4.io/api/v1 without adding /chat/completions.
Authentication fails
Use the API key created on DeepSeek-V4.io. Keys from other providers are not accepted.
Existing task keeps the old model
Save the settings and create a new Cline task.
Sources and support boundary
Configuration fields are checked against the tool publisher's documentation. DeepSeek-V4.io owns this gateway guide and support for its endpoint; it does not represent the tool publisher.
