Google Cloud Launches Gemini Agent: Runs in Your Inbox, Picks Between Gemini and Claude, Gives Subagents Email Addresses
Google Cloud announced the Gemini agent at Gemini at Work 2026 on October 8, positioning it as a single-interface universal agent for enterprise work: one prompt box covering email, documents, spreadsheets, and code, embedded inside the tools employees already use.
What it does
The Gemini agent runs inside Google Workspace — Gmail, Docs, Sheets, Calendar — and also inside Microsoft 365 and Slack. A user types a prompt; the agent plans the work, selects tools, connects to the company’s internal business systems, and returns finished output directly in the originating application: a replied email, a drafted document, completed code.
Model routing is automatic. The agent currently picks between Google’s Gemini models and Anthropic’s Claude on a per-task basis. Google said additional models will be added over time. That positioning makes the Gemini agent an orchestration layer across competing model providers, not a channel for Gemini consumption alone.
Coworker agents
Teams can create coworker agents — persistent sub-agents assigned their own email addresses and scoped to only the information they need. The design lets organizations build team-member-style AI roles rather than single-use task automation: a finance agent that handles one category of invoices, a legal agent with access to contract repositories, neither of which can see each other’s data.
Vertical versions
Financial services and legal editions are in preview as of October 8. Healthcare, government, and retail versions are on the roadmap.
Competitive positioning
The announcement is a direct response to Microsoft Copilot, which uses a similar embed-everywhere deployment model. Microsoft Copilot also runs across multiple model providers, but Google’s explicit third-party model routing — surfacing Claude as a peer option rather than a backend detail, is a marketing differentiator. It also introduces a complexity: when Claude processes a task inside Gmail through the Gemini agent, the data path runs through Google’s infrastructure. Enterprise procurement teams will need clear answers on where that data lands and which terms govern it — Google’s or Anthropic’s.
Google framed the launch around the shift from AI assistants to AI agents: models that return finished work rather than draft suggestions. The Gemini agent is the first Google product to make that promise explicitly inside Microsoft’s productivity suite.
