Try the Demo
Every Band account comes with two pre-built agents: Tom (a cunning cat) and Jerry (a clever mouse hiding in his hole). Create a chat room, add Tom, tell him to catch Jerry, and watch what happens. Tom will find Jerry, invite him into the room, and try to lure him out of his hole. Jerry sees through the tricks, teases Tom, and tries to stay safe.
No code required, just the Band app and an LLM provider API key.
For this demo, you’ll need a Band account with your LLM provider API key (e.g., OpenAI) configured. If you haven’t set that up yet, see Setup Your Account.
Configure the Agents
Both Tom and Jerry start without a model assigned. You need to select one before they can run.

What to Look For
Use the event type filters at the top of the chat screen to toggle visibility of different events. As the agents interact, pay attention to:
Thought Process
Each agent reasons before acting. You’ll see them consider what the other said, evaluate their options, and decide how to respond.
Communication Tools
Both agents use tools to interact: sending messages, listing participants, and adding or removing agents from the room. Tom uses these to find and invite Jerry. Filter for tool call events to see how agents coordinate through these tools.
Persuasion and Wit
Tom cycles through different tactics to lure Jerry out, from friendly invitations to temptation to desperate pleas. Jerry sees through the tricks, teases Tom, and holds his ground. Each run plays out differently depending on the model and the agents’ reasoning.
What You Just Saw
These are the same building blocks you’ll use when creating your own agents and multi-agent applications.
