The Arrival of Agents: Project Mariner and Agent Mode

A significant conceptual shift this year is the advent of agents—systems that combine model intelligence with tools and the ability to take actions under your discretion.

• Project Mariner is a research prototype capable of using a browser like a human: reading webpage content, planning steps, clicking buttons, scrolling, filling forms, and completing tasks from beginning to end. Google has introduced multitasking support (up to 10 tasks) and a method called ‘teach and repeat,’ where you demonstrate a workflow once, and the agent can replicate it in similar scenarios later. Limited access began in December 2024, with broader expansion in 2025, and it will be integrated into the Gemini API.

• Agent Mode in the Gemini app will enable subscribers to delegate tasks such as apartment hunting. In demonstrations, Agent Mode can adjust filters on platforms like Zillow, utilize external tools through the Model Context Protocol (MCP), and coordinate actions such as scheduling tours. Initial testing is underway, with wider access planned in the future.

To enhance agent interoperability, Google introduced the Agent2Agent (A2A) protocol, allowing agents from different vendors to communicate and collaborate. They are also adopting MCP compatibility in the Gemini API and SDK, linking agents to various tools and services. A2A has progressed under an open governance structure, and a proposed Agent Payments Protocol (AP2) aims to standardize how agents authorize and finalize transactions.

Why it matters: Agents can save significant time on complex tasks, and open protocols reduce vendor lock-in by facilitating collaboration between different agents.
