How Block powers collaborative AI agents with Buzz and Unity Gateway

Inside Block, Buzz brings employees and AI agents into a shared workspace. With Databricks Unity Gateway, employees who use Buzz can access frontier and open-weight models, experiment with different agent harnesses, and find the right combination based on the efficiency frontier for each task.

As AI agents become part of everyday work, Block’s teams needed a way to work with agents in the same place they work with each other. Block developed Buzz, an open source collaboration space where people and AI agents can work together in group discussions, focused conversations, and one-on-one exchanges.

Buzz brings agents into the same collaborative environment as employees. Users can create an agent, choose the model or coding harness behind it, and bring that agent into a conversation with colleagues. Rather than switching between different AI tools, teams can work with multiple agents in one place. 

At Block, Databricks Unity Gateway helps power the Buzz experience by providing access to a broad selection of frontier and open-weight models through a single integration. That gives employees the flexibility to experiment with different models and match them to the work they're trying to accomplish.
