# Vertex AI Is Gone. What the Gemini Enterprise Agent Platform Means for Founders

> Google renamed Vertex AI to the Gemini Enterprise Agent Platform and folded Agentspace into it. Your API endpoints didn't change — but the console, the billing, and the mental model did. Here's the map from old names to new, and the one line item worth a second look.

## Key takeaways

- At Cloud Next 26 (April 22, 2026) Google renamed Vertex AI to the Gemini Enterprise Agent Platform and merged Agentspace and the Gemini Code Assist enterprise tier into one console and one billing surface; Vertex AI stopped appearing in the Cloud Console around May 21
- The important part isn't the name — it's the inversion. Vertex was a model platform with agent features bolted on; the new platform is agent-first, and model training, AutoML, the Model Registry, and Endpoints are now sub-features under it
- Your code does NOT break: the API endpoints are unchanged, so anything wired to Vertex keeps working. What moved is where you find things in the console, how billing is grouped, and what the docs call each service
- Two renames matter operationally: 'Agent Engine,' the managed runtime for deploying agents, is now 'Deployments'; and there's a first-class managed 'Memory Bank' for long-term agent memory — worth knowing if you were about to build that yourself
- A2A (Agent2Agent) v1.0 ships as the default interop layer, and a no-code 'Workspace Studio' builder sits alongside 200+ models in the Model Garden — signals that Google is competing on the agent stack, not just the model

## At a glance

| What you knew it as (Vertex AI) | What it's called now | What actually changed |
| --- | --- | --- |
| Vertex AI | Gemini Enterprise Agent Platform | The umbrella product name; the API endpoint is unchanged |
| Agentspace (separate product) | Folded into the Agent Platform | One console and one billing surface instead of three |
| Agent Engine (managed agent runtime) | Deployments | Same managed runtime, new menu name |
| (new) | Memory Bank | Managed long-term memory for agents — a build-vs-buy decision you now get for free to consider |
| Model Garden, AutoML, Model Registry, Endpoints, Pipelines | Sub-features under Agent Platform | Demoted from the headline to components of an agent-first stack |
| A2A protocol (preview) | A2A v1.0, default interop layer | Promoted to the platform's standard agent-to-agent layer |
| (no-code builder) | Workspace Studio | New low-code path to assemble agents over 200+ Model Garden models |

**The short version:** Google renamed **Vertex AI** to the **Gemini Enterprise Agent Platform** at Cloud Next 26 (April 22, 2026) and folded the old **Agentspace** and the Gemini Code Assist enterprise tier into it — one console, one bill. Your API endpoints are **unchanged**, so nothing in your code breaks. What changed is where things live, what they're called, and the mental model behind the whole thing. Here's the map.
The rename you can ignore, and the one you can't
Most of this is cosmetic and backward-compatible. Per Google's own [name-changes doc](https://docs.cloud.google.com/gemini-enterprise-agent-platform/vertex-ai-name-changes), the request surface didn't move — if your service was wired up against Vertex AI, it kept running the day the sign on the door changed. There's no migration fire drill. Vertex AI simply stopped appearing as its own product in the Cloud Console around May 21, 2026, and its features — Model Garden, AutoML, the Model Registry, Endpoints, Pipelines — now sit as components *inside* the Agent Platform.
The rename you can't ignore is quieter: **Agent Engine is now "Deployments."** That's the managed runtime you use to deploy and scale an agent. Same service, new menu name. If your runbooks, internal docs, or onboarding guides say "Agent Engine," they're now pointing at a label that isn't in the console. Grep your wiki and fix the word; you don't have to touch the workflow.
The real story is the inversion
Strip the branding and here's what actually happened. Vertex AI was a **model platform** — training, tuning, serving — that had grown some agent features on the side. The Gemini Enterprise Agent Platform flips the hierarchy. Agents are the headline now; model training, AutoML, the Model Registry, and Endpoints are demoted to sub-features of an **agent-first** stack. As [AIwire put it](https://www.hpcwire.com/aiwire/2026/04/23/google-unveils-gemini-enterprise-agent-platform/) at launch, Google expanded Vertex "into a full agent stack" rather than adding another SKU.
Two moves make the intent obvious. Google shipped the **[A2A protocol](https://a2a-protocol.org/) v1.0** as the platform's default agent-to-agent interoperability layer — the same [Agent2Agent standard](/posts/a2a-vs-mcp.html) it has been pushing across the industry — and bundled a no-code builder, **Workspace Studio**, on top of 200+ models in the Model Garden. When a hyperscaler makes interop the default and hands non-engineers an agent builder, it isn't defending a model business. It's betting on the [full agent stack](/posts/bedrock-vs-vertex-ai-vs-azure-ai-foundry.html).
The one line item worth a second look
Buried in the consolidation is **Memory Bank**: a managed service that stores [long-term memory](/topics/agent-memory) for agents so they carry context across sessions. If you're building on Google Cloud and had "stand up an agent memory layer" on your roadmap, this turns it into a **build-vs-buy** question you should answer deliberately, not by default.
That's not a rubber stamp for the managed option. Agent memory is a crowded field, and a managed Memory Bank trades control and portability for one less thing to run — the same tradeoff [every memory decision comes down to](/posts/mem0-vs-zep-vs-letta-agent-memory.html). But it's now sitting in the same console as your deployments, which means the path of least resistance points at it. Know it's there, benchmark it against a dedicated memory system on *your* data, and choose on the merits instead of on where the button happens to be.
What to actually do
Three things, in order. **One:** don't panic — your endpoints work, this is not a migration. **Two:** update the vocabulary in your docs and dashboards (Vertex AI → Gemini Enterprise Agent Platform; Agent Engine → Deployments), because stale names cost your team search time. **Three:** if agent memory or agent-to-agent interop is on your roadmap, re-open those decisions now that Memory Bank and A2A v1.0 are first-class in the platform you're already paying for. The name change is free to ignore. The re-org underneath it is worth ten minutes.

## FAQ

### Did my Vertex AI code break when it became the Gemini Enterprise Agent Platform?

No. Google kept the API endpoints unchanged, so existing integrations wired to Vertex AI keep working without edits. What changed is the console layout, the billing grouping, the product names in the docs, and where features live in the menus — not the request surface your code calls.

### What is the Gemini Enterprise Agent Platform?

It's Google's rebrand and consolidation of Vertex AI, announced at Cloud Next 26 on April 22, 2026. It merges the old Vertex AI, Agentspace, and the Gemini Code Assist enterprise tier into a single agent-first platform with one console and one billing surface. Vertex AI stopped appearing as its own product in the Cloud Console around May 21, 2026.

### Where did Agent Engine go?

It was renamed 'Deployments.' It's the same managed runtime for deploying and scaling agents — only the menu label changed. If your runbooks or docs reference 'Agent Engine,' update the name but not the workflow.

### What is Memory Bank and should I care?

Memory Bank is a new managed service in the platform that stores long-term memory for agents so they can carry context across sessions. If you were planning to stand up your own memory layer on Google Cloud, it's now a build-vs-buy question worth pausing on — evaluate it against a dedicated memory system before you write your own.

### Is this just a rebrand, or did the strategy change?

Both. The names moved, but the hierarchy inverted: Vertex used to be a model platform with some agent tooling; the Gemini Enterprise Agent Platform makes agents the headline and demotes model training, AutoML, the Model Registry, and Endpoints to sub-features. Shipping A2A v1.0 as the default interop layer and a no-code Workspace Studio builder signals Google is competing on the whole agent stack, not just the model.
