Google Vertex AI API is the main cloud API provided by Google Cloud for building, deploying, and managing machine learning (ML) and generative AI models at scale. It’s a comprehensive platform that allows you to use powerful Google and third-party AI models (like Gemini), train your own models, deploy them to production, and manage the whole machine learning lifecycle — all through a single set of REST/gRPC APIs.
Key Points About Vertex AI API
- Unified ML Platform: Combines Google’s ML tools, including model training, prediction (inference), MLOps (like pipelines, experiments, monitoring), data labeling, and feature store.
- Model Garden: Gives access to Google’s latest generative AI (Gemini), open-source, and third-party models.
- Custom Model Training: Train models with your own code (TensorFlow, PyTorch, etc.) or AutoML.
- Flexible Deployment: Deploy models for real-time or batch predictions. Scale from test to massive workloads.
- Multimodal Capabilities: Supports text, image, video, and audio inputs—especially with generative models like Gemini 1.5/2.
- Enterprise Ready: Security, compliance, region selection, versioning, monitoring, quotas, and billing.
Common Uses
- Access Gemini (or Claude, Imagen, etc.) for text, image, and video generation
- Train, deploy, and manage custom ML models
- Automate data pipelines and MLOps workflows
- Integrate AI models into web, app, and backend solutions using the Vertex AI API
How to Use Vertex AI API
You can interact with the Vertex AI API through:
- Google Cloud Client Libraries (Python, Java, Go, Node.js, etc.)
- REST API and gRPC API
- Google Cloud Console UI for setup and monitoring
Sample (Python):
from google.cloud import aiplatform
aiplatform.init(project='my-project', location='us-central1')
model = aiplatform.Model("gemini-1.5-pro-001")
response = model.predict(["Hello, what is Vertex AI?"])
print(response)
Code language: JavaScript (javascript)Vertex AI API vs Gemini API
- Gemini API: For fast prototyping with Gemini models only (simple API key, fewer features).
- Vertex AI API: For production, security, multi-model, and full ML workflows; supports more regions, authentication, compliance, and advanced features.
When to Use Vertex AI API?
- For production apps and integrations.
- When you need to manage, deploy, or fine-tune models.
- If you need enterprise support, GCP integrations, or regional/data compliance.
In short:
Google Vertex AI API is the backbone of Google Cloud’s enterprise-grade AI—providing a single API and platform to access, deploy, manage, and monitor all types of AI models, including generative, custom, and open-source.
