# Chat

> Chat with a deployed Agent host agent in real time: how the connection is made, what you see, and limits on message length.

Source: https://agenthost.geenius.io/docs/chat/

Open an agent and choose Chat. The browser connects to the agent's own runtime with a ticket the hub made after checking your seat.

- Type a message; the agent answers.
- Safe tool calls are made by the agent; a risky one is suspended and shows an approval card.
- The conversation is kept.
- A message can be up to 8,000 characters.

An agent must be deployed to chat.
