Cline

Use Foza models with the Cline VS Code extension

Setup#

Use Cline's OpenAI Compatible provider, not the native OpenAI provider. The compatible provider is the one that exposes Base URL, API Key, and Model ID fields.

Install Cline

Install the Cline extension from the VS Code Marketplace.

Open Cline Settings

Click the Cline icon in the sidebar, then click the Settings gear icon.

Select API Provider

Choose OpenAI Compatible as the API provider.

Configure connection

Set the following fields:

Base URL: https://api.foza.ai/v1
API Key: sk-foza-xxxxx
Model ID: Enter your model slug, e.g., anthropic/claude-sonnet-4.6 or openai/gpt-4o

Tune request settings

Start with conservative settings:

Temperature: 0.2 to 0.5
Max output tokens: 4096 or higher for coding tasks
Auto-approve: off until you trust the workflow

Run a verification task

Ask Cline:

Read the project structure and tell me which files you would inspect before changing the login page. Do not edit files.

Troubleshooting#

Symptom	What to check
`Model Not Found`	The Model ID must match a Foza model slug exactly
`Invalid API Key`	The key is active and subscribed to the selected model
404 errors	Base URL should be `https://api.foza.ai/v1`, not the chat completions endpoint
Poor code edits	Switch to a stronger coding model such as a Claude Sonnet-class model

Cline supports all OpenAI-compatible APIs, so any model subscribed to your Foza key will work.
