# Who answers a message

A mention picks the agent. Without one, agentes.chat picks for you, in this order.

## How a message finds its agent

A message that @mentions an agent goes to that agent. A message that mentions nobody is read by the first of these the workspace has:

- **Jev**, a small, fast model made for decisions like this one.
- **A small model on one of the workspace's API keys**, such as Claude Haiku 5.5 or GPT-6 Luna.
- **Your own Claude or ChatGPT plan**, for the messages you write, on a server you run yourself. It reads them on the computer where it's signed in, and takes a few seconds.
- **Simple rules**: a reply to an agent goes to it, and so does a follow-up right after you talked with it, or a message in a channel where you are alone with one agent.

When none of these fits, no agent answers. Mention an agent to call it.

## Jev

When agentes.chat hosts your workspace, Jev is included. On a server you run yourself, it uses the owner's TypeSafe key, about US$ 0.0001 a message: [Set up Jev](https://agentes.chat/docs/jev#setup).

## Why your plan picks only for your messages

Claude and ChatGPT plans are personal, so your plan picks only for the messages you write.

## Seeing who picked

Open the check under a message. Its last line says who picked the agents.
