According to AndrewYNg on X, DeepLearning.AI launched a short course on the A2A (Agent2Agent) Protocol, built with Google Cloud and IBM Research and taught by Holt Skinner, Iván Nardini, and Sandi Besen, to standardize communication between AI agents across different frameworks. As reported by AndrewYNg, the course addresses the costly custom integrations typically needed to connect heterogeneous agent systems, offering a repeatable protocol layer for interop and orchestration. According to AndrewYNg, this creates business opportunities for multi‑agent applications—such as enterprise workflows, customer support, and supply chain automations—by reducing integration time, improving reliability, and enabling vendor‑neutral agent ecosystems.
