This uses the <a href="https://aistudio.google.com/app/apikey">Google AI Studio</a> backend.</li> <li><strong>Vertex AI (ADC):</strong> Used if provided <code>project</code> and <code>location</code> (or set <code>GOOGLE_CLOUD_PROJECT</code>/<code>GOOGLE_CLOUD_LOCATION</code> environment variables). This uses <a href="https://cloud.google.com/docs/authentication#adc">Application Default Credentials (ADC)</a>.</li> </ol> <p>We recommend using an API key for quick testing and using Vertex AI with ADC for production environments.</p>
