AI / Google Antigravity Gemini Fundamentals Interview Questions

What is Google AI Studio and how does it differ from Vertex AI for Gemini access?

Google AI Studio (aistudio.google.com) and Google Cloud Vertex AI are two distinct pathways to access Gemini models. Choosing the right one depends on your scale, compliance requirements, and cloud strategy.

Google AI Studio vs Vertex AI
AspectGoogle AI StudioVertex AI
Target userIndividual developers, startups, prototypesEnterprise, regulated industries, large scale
SetupSign in with Google - get API key instantlyRequires Google Cloud project and billing
Free tierYes (limited RPM/RPD)No (pay per token from first call)
Data privacyMay use free tier data to improve modelsBusiness data NOT used for training
ComplianceStandardSOC 2, HIPAA, VPC Service Controls
Model availabilityLatest models first, some preview accessStable enterprise releases, some delay
Additional featuresPrompt testing, tuning, evaluationMLOps pipelines, Model Garden, training
BillingPer token after free tierPer token, enterprise pricing
SDKgoogle-genai with GEMINI_API_KEYgoogle-cloud-aiplatform or google-genai
# Google AI Studio (simple)
from google import genai
client = genai.Client()  # reads GEMINI_API_KEY

# Vertex AI (enterprise)
from google import genai
client = genai.Client(
    vertexai=True,
    project="my-gcp-project",
    location="us-central1",
)
# Vertex AI also accepts service account credentials
# and integrates with IAM roles

For a startup building a consumer app that needs to control AI costs carefully, which access path is better?
What is a key data privacy difference between using Gemini via Google AI Studio free tier vs Vertex AI?
