PubNub introduces Blocks.ai, a global network to connect and control agents across all agent frameworks, providers, and APIs. Blocks.ai lets developers reach their existing AI agents regardless of where they are hosted. Blocks Network supports all AI agent use cases without opening inbound ports, setting up tunnels, changing DNS, or modifying firewall rules. For more than a decade, PubNub has been the infrastructure and platform for real-time connectivity supporting billions of devices; now, PubNub delivers Blocks Network, connecting the Internet of Agents.

AI agents have become increasingly critical to businesses who want control over their models, code, and data. But once those agents are running locally or behind a firewall, making them reachable from custom frontends can require brittle infrastructure work. This is a key reason why McKinsey estimates that fewer than 10 per cent of enterprise agents have ever reached production. Blocks Network is designed to remove that barrier while keeping the agent private and under the builder’s control.

Blocks Network works in both directions. Developers who don't run an agent of their own can still draw on Blocks Network: any application, web app, backend service, or mobile app can discover capability-specific agents on the network and call them with a few lines of code using the open-source SDKs. Instead of managing a different API key for every provider and building a new integration for each capability, a developer adds AI functionality in the way they'd call any function. The agents behind those capabilities keep running wherever their builders host them.

“You can build a great agent in an afternoon, but it often just sits there, isolated on your machine,” said Todd Greene, CEO of PubNub. “With Blocks, build an agent, connect it once, and it’s available to any frontend, application, or user who needs it. Blocks Network is the global agent control plane to connect, call, and share efficiencies without rebuilding anything.”
