Alphabet (GOOG) Google Cloud Next 2026 Developer Keynote summary

Keynote announcements and platform overview

• Introduced the Gemini Enterprise Agent Platform, enabling autonomous agents to proactively assist users and complete tasks independently, powered by Gemini Pro and Flash models, with support for other models via Model Garden.

• Agent Development Kit (ADK) provides tools and ready-to-use skills for building, scaling, and optimizing agents, with all Google Cloud services now MCP-enabled by default.

• Agents communicate securely via unique Agent Identity, governed by policies enforced through Agent Gateway, and can collaborate using Agent Registry and the A2A protocol.

• Shared context across Gemini Enterprise, Workspace, and third-party agents enables ecosystem-wide collaboration.

Developer and industry use cases

• Developers leverage Gemini to transform complex data into interactive visualizations, such as isometric maps of New York City.

• Cloudphysician's AI platform, built on Google Cloud, reduced ICU mortality by 47% by connecting bedside teams with central care specialists.

• Language learning apps and simulation tools are being rapidly developed using GenUI SDK, Firebase, and Gemini.

• Genie 3 world models are used for simulating edge-case scenarios, such as traffic for autonomous vehicles.

Agent-based simulation demo: marathon planning

• Demonstrated a multi-agent system simulating marathon planning in Las Vegas, with agents for planning, evaluating, and simulating routes.

• The planner agent uses mapping, GIS, and race director skills, integrating Google Maps and historical planning documents.

• Evaluator sub-agent grades routes on deterministic and non-deterministic criteria, while the simulator agent models real-world behaviors and city impact.

• Agents dynamically generate user interfaces using A2UI, and collaborate seamlessly via A2A protocol and Agent Registry.
