A pause saves each agent’s conversation to your disk.

You do not have to finish your work before turning off your computer. A pause saves each agent’s conversation and stops everything; resuming puts each agent back in front of its conversation, where it left off. Stopping, on the other hand, is permanent: that is the one thing not to confuse on this page.

## The life cycle of a session

An agent session starts, the agents work, the pause saves everything to disk, and resuming gives them back their conversation, even after turning off the computer. From the work in progress, stopping interrupts everything and cannot be undone. — Launch — your agents — start up — They work — one pane — per agent — Pause — saved — to your disk — Resume — they get back — their conversation — even after — turning off your computer — or — Stop — any work in progress is interrupted — this action cannot be undone

A session starts, works, pauses, and resumes as many times as needed. Stopping is the only irreversible exit.

## Pause or stop

|  | Pause | Stop |
| --- | --- | --- |
| The agents | Are stopped | Are stopped |
| The conversations | Saved to your disk | Lost |
| Work in progress | Saved with the conversation | Interrupted |
| Resume possible | Yes, at any time | No, it cannot be undone |
| The project | Stays open | Closes, and sync with Studio stops |

In both cases, your code stays saved: the project is saved automatically, independently of the agents. See [Your code is saved automatically](/en/application/projet/sauvegarde/).

## Pause

1.  Click Pause, to the right of the project bar. The dialog “Pause the agents?” opens.
2.  Read what it says: “Each conversation is saved, then the agents stop. Resume anytime, even after a restart.”
3.  Confirm with Pause Session. The app shows “Pausing agents…,” and then everything stops.

### The special case of OpenCode

An OpenCode agent cannot be saved in the middle of a turn. If one of them is still working, the app asks you to choose between two buttons:

-   Wait for any turn in progress, then pause
-   Interrupt any turn in progress, then pause

If all your OpenCode agents are idle, both buttons do the same thing.

If the pause is refused, nothing has been touched

The message is explicit: “An OpenCode agent has never finished its turn — it is still working, or it is waiting for an answer from you. **Nothing has been saved and nothing has been stopped.**” Look at the pane concerned: it is often just waiting for your answer. Otherwise, run the pause again and choose

Interrupt any turn in progress, then pause to cut its turn cleanly.

## Resume

1.  Reopen the project. The banner “Paused session found” appears, with how long the session has been paused, the number of agents, and the number of tabs.
2.  Click Resume session. Or click Delete if you want to start from an empty session.
3.  During the resume, the app shows “Resuming — checking each agent picked its conversation back up…”
4.  Pick up the thread in each pane: the agents have their conversation, their plan, and their context.

The Continue anyway button is available if the check takes too long. It warns of its effect: “agents that did not respond will start from scratch.”

Restart a single agent

You do not need to resume the whole session for one agent that has stopped responding: in the header of its pane, Restart and resume agent relaunches it with its conversation.

## Close the app

Closing the app stops all running sessions. It offers a pause instead: accept it if you plan to resume.

## What a pause costs in quota

The pause itself uses nothing: nothing is running. What costs quota is **resuming an old conversation**, because its entire context is read again. Resuming the next morning has no real cost; resuming a conversation that is several days old can seriously use up your quota.

The habit that saves the most: finish a task before pausing, and open a new conversation for the next task. See [Making your quota last](/en/application/agents/choisir-son-ia/).

## Find a conversation without a paused session

If you closed the app without pausing, the conversation is not necessarily lost: the agent tools have their own resume command, `/resume`, which lists previous conversations in the agent’s terminal.

To undo what an agent has just done, Claude Code offers `/rewind`. Codex does not have it. Otherwise, go back to an earlier version of your project: [Going back to an earlier version](/en/application/projet/versions/).

## Limits

-   **An OpenCode agent may start from scratch when resumed.** The message says: “The session is back, but an OpenCode agent did not get its conversation back — it is starting from scratch. Everything else has picked up where it left off.” This is a limit of OpenCode, not a loss of project data.
-   **Stopping cannot be undone.** The “Stop the agents?” dialog says so: “Every agent stops, its work in progress is lost and the project closes. This can’t be undone.”
-   **A pause does not save your Roblox place.** Also save your work in Roblox Studio before closing.

## Frequently asked questions

**“I have to turn off my PC. Will I lose everything?”** No, if you pause. The session is written to your disk and survives a restart.

**“Pause or stop at the end of the day?”** Pause, unless you have finished and want to start something else tomorrow: a clean start costs less quota than a long conversation that you resume.

**“I closed the app and lost my conversation.”** Try `/resume` in the agent’s terminal. If it is not there, starting over with a clear instruction often costs less than rebuilding everything.

**“Can I launch other agents while a session is paused?”** Yes. While they are running, the project bar shows the “_N_ paused” badge; the paused session can be resumed once those agents are stopped or paused.
