# Vertex AI Vertex AI is [[Google]]'s managed AI platform on Google Cloud — the enterprise surface for building with [[Gemini]] models, as opposed to [[Google AI Studio]] (developer prototyping) and the [[Gemini Mobile App]] (consumers). In April 2026 Google rebranded and expanded it as the **Gemini Enterprise Agent Platform**, repositioning it from a model-serving platform into a full agent stack. The "Vertex AI" name is still widely used and remains the API surface, so both names point at the same product. ## What it covers - **Model Garden** — first-class access to 200+ models: Google's own ([[Gemini 3]] family, Gemini Flash Image, Lyria) and open weights ([[Gemma]] 4, third-party models) - **Agent Studio** — go from prompts to deployable multi-step agents without dropping into code - **Agent Development Kit (ADK)** — a graph-based, code-first framework that organises agents into networks of sub-agents - **Agent operations** — Agent-to-Agent Orchestration, Agent Registry, Agent Identity, Agent Gateway, Agent Observability - Training, tuning, and MLOps for custom models alongside the hosted frontier models ## Why it matters - Vertex AI is the distribution moat for Gemini in the enterprise — the role [[Google AI Studio]] plays for developers - The rebrand signals Google's bet that the unit of enterprise AI is the **agent**, not the single model call - For [[AI Agents|agentic]] workloads it bundles identity, orchestration, and observability that teams would otherwise assemble themselves ## Caveats - The platform and its naming move fast (the April 2026 rebrand is one of several); check current Google Cloud docs before relying on specific feature names - Model availability on Vertex AI can lag the consumer Gemini App and AI Studio for the newest releases ## References - Vertex AI Platform: https://cloud.google.com/vertex-ai - Gemini Enterprise Agent Platform announcement: https://cloud.google.com/blog/products/ai-machine-learning/introducing-gemini-enterprise-agent-platform - Model versions and lifecycle: https://docs.cloud.google.com/vertex-ai/generative-ai/docs/learn/model-versions ## Related - [[Google]] - [[Google DeepMind]] - [[Gemini]] - [[Gemini 3]] - [[Google AI Studio]] - [[Gemini Mobile App]] - [[AI Agents]] - [[Large Language Models (LLMs)]] - [[Gemma]]
