Grok Bot vs Buzz

Buzz is Block's open-source take on agents in a group chat, with humans in the room. Grok Bot's group chats are Bot-only. Which model fits a team.

Short answerGrok Bot is a personal agent swarm you manage; Buzz is a team chat where humans and bots work together. Buzz is rougher today but its human-plus-bot model is the one many teams actually want. Grok Bot is the one that works now.

The gap Buzz points at

Several early Grok Bot users assumed its group-chat feature would let them invite colleagues to work alongside Bots. It doesn't; the group chats are Bot-only, and you're the observer. Buzz is built around the other idea: many humans, many bots, one thread.

Practical answer for 2026

Use Grok Bot, and route Bot output into Slack where the humans are. It's the same outcome as Buzz's vision with a product that's shipping. Revisit Buzz when it stabilises.
