Cline is an AI-powered coding assistant. This tutorial demonstrates how to configure Cline to use models provided by Serverless Inference, so that you can use open-weight models hosted on W&B Inference for your coding tasks. The Cline agent is available as a command line tool or as an integration with many IDEs. The following sections describe configuration with the Cline CLI and with Cline as a Visual Studio Code extension. Configuration in other IDEs is similar.

​
Prerequisites

You need your W&B API key.

​
Set up Cline in the command line

Install the Cline CLI.
See Cline’s installation instructions for troubleshooting. Run cline version to verify what you have installed.

​
Use the native W&B provider

This configuration was tested with Cline CLI version 3.0.61 on macOS. Set the WANDB_API_KEY environment variable to your W&B API key. Then run:
The provider’s command-line ID is wandb. Depending on your Cline version, the provider appears as Weights & Biases or W&B. Cline uses that provider’s configured Serverless Inference endpoint. If Cline responds with an answer, the connection is working.

​
Use the OpenAI-compatible provider

The following instructions were tested with Cline CLI version 2.5.1. Next, authenticate Cline against the Serverless Inference endpoint. The following command configures Cline to use the Serverless Inference OpenAI-compatible endpoint and the Kimi K2.6 model. Substitute [YOUR-API-KEY] with your W&B API key.
For model availability and pricing, see the W&B Inference model catalog. Run a test to verify everything is working:
If Cline responds with an answer, your installation and authentication are complete. For more information about using the Cline CLI, see the Cline Quickstart.

​
Set up Cline in Visual Studio Code

If you prefer to use Cline inside an IDE, you can install it as a Visual Studio Code extension. Search for Cline in the VS Code Extensions Marketplace, or install it from the Visual Studio Code Marketplace. Click Install.
VS Code extension installation
Click the newly added Cline icon in your Activity Bar to open the Cline sidebar. If the Cline icon isn’t showing in the Activity Bar, click the dropdown to see more options. Cline icon in the VS Code Activity Bar Select Bring my own API key and click Continue. Select Bring Your Own Key Specify the following values, substituting [YOUR-API-KEY] with your W&B API key: Specify pricing by expanding Model Configuration. Click Continue. Try submitting a prompt like “Write a Python program to compute the first 10 Fibonacci Numbers”. Submit your coding task to the agent For more information about using Cline, see the Cline Documentation.
