This is a submission for the Google Cloud NEXT Writing Challenge The shift from simple AI pilots to fully autonomous digital task forces is officially here! With the release of the Gemini Enterprise Agent Platform at Google Cloud Next '26, developers can now build, scale, and govern agents with the same rigor applied to mission-critical systems. We are moving beyond standalone models and stepping into a brave new world where agents seamlessly discover and collaborate with each other using the Agent Registry and the universal A2A protocol.
