Multi-run

Run one prompt across several models at once to compare their results.

Launching a Multi-run

Open a repository and click Multi-run in the header, next to New Session. In the Launch tab:

Give the run group a Group name.
Enter the Prompt to send to every model.
Select up to five models from the checkbox list, grouped by provider.
Leave Isolate runs on to give each model its own workspace.
With Isolate runs on, optionally change Start from: a local or origin branch. It defaults to the repository's current branch.

Click Launch. Each selected model gets its own session, and the same prompt is sent to all of them. Models are checked before any workspace is created, so a model that is not available fails its entry without creating a workspace while the other models still launch. Launching is parallel, and one model failing does not stop the others: the failed entry records its error while the rest keep running.

Isolation

With Isolate runs on, each run is created in its own OpenCode workspace: a detached checkout of the repository at the chosen ref, with no branch created. These workspaces appear in the repository's Workspaces tab, and the session for an isolated run opens with that tab selected. With isolation off, every run shares the repository directory.

Runs

The Runs tab lists the 20 most recent groups and their entries. Every entry shows the model, its status, and for a started run the live session status indicator. From here you can:

Open a run to view its session and compare the result.
Discard a run after confirmation. Discarding an isolated run also removes its workspace directory from the Workspaces tab; if that workspace was already removed, for example from the Workspaces tab, discarding still succeeds. A non-isolated run keeps its session in the repository.

Discarding is irreversible and cannot be repeated on an already discarded run. Deleting a repository removes its multi-run history.
