# Rollouts

> Understand what a rollout is and browse the rollouts synced from your workspace repository

A **rollout** is the unit of agent behavior that Osmosis evaluates and trains. It wires together an `AgentWorkflow`, which defines how the agent handles a prompt, calls the model, and uses tools, and a `Grader`, which scores each result into a numerical reward. When you submit an [evaluation run](/platform/evaluation-runs) or a [training run](/platform/training-runs), the platform executes the rollout once per dataset row and grades what it produces.

In the [Multiply Quickstart](/platform/quickstart), `multiply-local-openai` is a rollout: its `AgentWorkflow` asks the model to solve a multiplication prompt, and its `Grader` compares the answer to the row's `ground_truth`.

## What a Rollout Contains

Rollouts are code in your workspace repository, one directory per rollout under `rollouts/`, referenced by evaluation and training configs:

```text theme={"theme":{"light":"github-light","dark":"github-dark"},"languages":{"custom":["/languages/cli.json"]}}
repository/
├── rollouts/
│   └── my-rollout/
│       ├── main.py        # explicit workflow, grader, config, and backend wiring
│       └── pyproject.toml # rollout-local dependencies
├── configs/
│   ├── eval/
│   │   └── my-rollout.toml
│   └── training/
│       └── my-rollout.toml
└── data/
    └── test.jsonl
```

| `Grader`                  | Turns each result into the reward signal that drives training      | [Grader](/sdk/grader)                    |

For the full rollout definition — including execution backends and how rollouts fit the training loop — see the [SDK Overview](/sdk/overview).

## The Rollouts Page

The Platform **Rollouts** page lists every rollout discovered from your connected workspace repository. [Git Sync](/cli/workspace/git-sync) scans the `rollouts/` directory of each pushed branch, and each subdirectory becomes an entry showing its name, last synced commit, and last synced time. Selecting a rollout opens its source on GitHub at the synced commit.

Each branch has its own rollout catalog. The branch picker selects the repository default branch first.

<Note>
  The Rollouts page requires a connected workspace repository. If no repository is connected, set one up from **Git Integration** — see [Onboarding](/platform/onboarding).
</Note>

## Create a Rollout

Rollouts are created in code rather than in the dashboard. **New Rollout** shows the CLI command that scaffolds one in your local workspace clone:

```cli theme={"theme":{"light":"github-light","dark":"github-dark"},"languages":{"custom":["/languages/cli.json"]}}
osmosis rollout init <name>
```

Commit and push the generated files; the rollout appears on the Rollouts page after the branch syncs. You can also list synced rollouts from the CLI:

```cli theme={"theme":{"light":"github-light","dark":"github-dark"},"languages":{"custom":["/languages/cli.json"]}}
osmosis rollout list [--branch NAME]
```

To build a rollout for your own task with an AI coding agent, follow the [Custom Rollout Guide](/sdk/create-a-rollout).
