Google Cloud Next 2026: Agentspace Unified Into Gemini Enterprise

TL;DR

Agentspace, Google's 2025 agent layer, was unified into Gemini Enterprise Agent Platform at Cloud Next 2026. This is not just a rebrand — it changes what builders see in the console, where agents are deployed, how data integration works, and how the agent surface area is governed. This post walks the builder-facing changes: what moved, what is new, what is gone, and what a clean agent build looks like in the unified product.

What Agentspace Was

Agentspace launched in 2025 as Google's answer to enterprise agent builders. It had its own console, its own concept of an "Agent," a marketplace of pre-built capabilities, and a workspace-aware UX. It was popular with Workspace-heavy customers but lived awkwardly next to Vertex AI, which had its own Agent Builder and its own model garden. The result was two agent-building paths under one cloud.

What Unification Looks Like

In the unified Gemini Enterprise Agent Platform, builders see one console with three main areas:

1. Build — agent designer (visual + code), tools, prompt management, evals.
2. Deploy — managed serving, autoscaling, observability, version pinning.
3. Govern — IAM, audit, safety filters, data-residency policies.

The Agentspace marketplace, model garden, and workspace integrations now live under the same console — under tabs, not separate products. Existing Agentspace agents are migrated automatically and appear in the unified Build tab with their original names.

What Is Actually New In The Builder

Three concrete improvements that builders will notice on day one:

• Tools as first-class objects. Tools (functions the agent can call) are now versioned, eval-able, and shareable across agents in the same project. Previously you had to redefine them per agent.
• Eval suites bound to agents. Each agent has an eval suite that runs on every change. Pull-request-style review for agent edits is now possible.
• Pre-integrated partner agents. Box, Workday, Salesforce, ServiceNow, Dun & Bradstreet, and S&P Global ship as installable agents. We unpack the roster in the partner agents post.

Workspace Studio: The Workspace-Native Surface

Workspace Studio is the new in-Workspace builder — agents built next to your Docs, Sheets, Gmail, and Drive. It uses the same underlying Gemini Enterprise infrastructure, just with a Workspace-native UX. For knowledge-worker agents (research, summarization, draft generation), Workspace Studio is the path of least resistance. We have a walkthrough post.

Data Integration Is The Sleeper Feature

The biggest builder pain in 2025 was getting enterprise data into agents safely. The unified platform ships first-party connectors (BigQuery, Workspace, Drive, Cloud Storage) and third-party connectors (Box, Workday, Salesforce, ServiceNow) with IAM and VPC-SC baked in. The connectors are not new in concept; the unification is that they all live next to the agent builder rather than in a separate product.

A Clean Build, Step By Step

A reasonable first build in the unified platform:

1. Create an agent in the Build tab.
2. Choose Gemini 3.1 Pro as the base model (Flash-Lite for cheap workloads, Ultra for 2M-context cases).
3. Attach two or three tools — say, a BigQuery query tool, a Workspace search tool, a Salesforce read tool.
4. Define an eval suite of 30–50 examples covering the agent's primary intents.
5. Deploy to a private endpoint, run the eval suite, iterate.
6. Add governance: IAM roles, audit logging, safety filters.
7. Promote to production.

The whole loop is meaningfully faster than it was in late-2025 Vertex AI, mostly because the eval and governance surfaces are no longer afterthoughts.

What Is Gone

A few legacy concepts to know about:

• Agentspace Console URL. The console URL changed; old bookmarks redirect.
• Standalone Agentspace billing. Agentspace line items are merged into the Gemini Enterprise SKU.
• The "Agent Garden" name. The old Agentspace marketplace is renamed and integrated into Build.

Nothing is deleted for existing customers; everything is migrated and renamed.

How CallSphere Fits In

CallSphere is the voice and chat front-door, not an agent-platform replacement. In a Gemini Enterprise build, CallSphere handles the inbound call or chat — 57+ languages, six verticals (healthcare, real estate, sales, salon, IT helpdesk, after-hours), HIPAA-friendly, voice/chat/SMS/WhatsApp — and writes structured outcomes back to the connected systems (Salesforce, ServiceNow, etc.) via the same connectors Gemini Enterprise exposes. CallSphere lives next to Gemini Enterprise, with the front-door experience that ships in 3–5 days and prices at $149/$499/$1,499 per month. Try it free.

Builder Recommendations

A few honest recommendations:

• Start with Workspace Studio for knowledge-worker agents. The path of least resistance for Workspace-heavy teams.
• Use the full Gemini Enterprise Agent Platform for customer-facing or data-heavy agents. You will want the governance and connectors.
• Pair with a focused front-door for voice/chat. Latency budgets at the front door are tighter than what a general agent platform optimizes for.

FAQ

Do my Agentspace agents still work? Yes. They are auto-migrated into the unified Build tab. Review the migration before relying on it for production.

Did the SDK change? The Gemini Enterprise SDK is additive. Existing Vertex AI and Agentspace calls continue to work; new features ship through new surfaces.

Is the partner-agent install one-click? Effectively yes — you authenticate to the partner (Salesforce, Workday, etc.), grant scopes, and the partner agent is installed in your project with a default eval suite. The "first agent in production" milestone — which routinely took six weeks in 2025 — is now a same-week target. There is no automated cross-platform import for agents built on competing platforms in May 2026; you rebuild the orchestration in Gemini Enterprise and reuse the connectors.
