These limits apply to every OpenBeam Cloud account, whether you start a session with **Play** or an AI app starts it for you over MCP.

## Sessions

| Limit                             | Value                               | What you see                                                                                                  |
| --------------------------------- | ----------------------------------- | ------------------------------------------------------------------------------------------------------------- |
| Sessions at a time                | 1 per account                       | Starting another one asks **End your other session?** Choose **End it and play here** to move it to this tab. |
| Session length                    | Up to 4 hours                       | *The session reached its time limit.* Press Play to start a new one.                                          |
| Time to open the player           | 2 minutes after the server is ready | *The player took too long to connect.*                                                                        |
| Time away before the session ends | 5 minutes                           | *The player was away for too long.*                                                                           |

### If you close the tab or lose your connection

Your session keeps running for 5 minutes. Open OpenBeam Cloud again and press **Play** within that time and you rejoin the same game (*Rejoining your running session…*). After 5 minutes the session ends.

**Leave** in the player's toolbar ends the session straight away. Use it when you are done, so you are not counted for time you don't use.

### When every GPU is busy

If no GPU is free, OpenBeam Cloud starts another server for you and waits for it (*Starting another server for you.*). If none comes free in time you see *No server came free in time*; try again in a few minutes.

## Monthly hours

How many hours you get each month depends on your plan. See [Plans, hours and billing](https://openbeam.world/docs/plans-and-billing/). Hours are counted per stream while a solver is attached; queued and idle time isn't billed.

If you joined with a beta invite, the invite can set its own number of sessions. Once they are used you see *This invite's game session has been used*, and you need a new invite to start another.

## Mod library

| Limit                | Value |
| -------------------- | ----- |
| Mods in your library | 50    |
| Total library size   | 10 GB |
| Size of one mod      | 4 GB  |

When you reach a limit, delete a mod you no longer need under **Mods**. See [Upload and share mods](https://openbeam.world/docs/upload-and-share-mods/).

## Recordings

A recording stops on its own before its video reaches 8 GB, or if the stream changes size or codec. Everything recorded up to that point is saved. See [Record a run and download its data](https://openbeam.world/docs/record-and-download-data/).
