Use Claude Desktop with InferFoundry

Claude Desktop is Anthropic's native desktop app for macOS and Windows. You can route it through InferFoundry by configuring it as a custom OpenAI-compatible provider — keeping your conversations processed in your chosen region.

Prerequisites

Configuration

Claude Desktop reads its configuration from a JSON file.

Locate the config file

~/Library/Application Support/Claude/claude_desktop_config.json

%APPDATA%\Claude\claude_desktop_config.json

Edit the config

Open the file (create it if it doesn't exist) and add an openai provider block:

{
  "openai": {
    "baseUrl": "https://gateway.dev.if-service.ai/v1",
    "apiKey": "your-api-key-here"
  }
}

Replace [your-region] with your actual endpoint from portal.dev.if-service.ai.

Restart Claude Desktop

Quit and reopen the app. Your InferFoundry models will appear in the model selector.

Available models

See Available Models for the full list. Use the model ID exactly as shown (e.g. claude-sonnet-4-5).

Troubleshooting

Models not showing up
Verify the baseUrl ends in /v1 and the apiKey is correct. Check the Claude Desktop logs for connection errors.
"Unauthorized" error
Confirm your key is active in portal.dev.if-service.ai → Keys.
Requests going to Anthropic
If you're logged in to Claude Desktop with an Anthropic account, log out from the app's account settings before testing the custom provider.
