Google Vertex AI

Integrate Google Vertex AI models through the Adaline Proxy to automatically capture telemetry — requests, responses, token usage, latency, and costs — with minimal code changes. Vertex AI provides enterprise-grade access to Gemini models through your Google Cloud project.

print(response.text)
Vertex AI uses vertexai=True and requires a GCP project and location, unlike Google AI Studio which only needs an API key. Headers are passed via http_options.
