​
Step 3: Configure your provider

In BrowserOS, paste the model ID into Model ID field. The model ID should be in the format shown under “Custom” (e.g., openai/gpt-4.1-mini). Paste your OpenRouter API key, set Context Window Size based on the model, and check Supports Images if the model supports it. Click Save. SCR-20251007-kfel.png Done! You can switch between different models anytime by creating new providers with different model IDs.
