 All of these examples require `OPENAI_API_KEY`, because they call the model through the normal `Runner` path. Each cloud backend also needs its own provider credentials.
 
+## Migrating from Runloop
+
+Runloop support has been removed from `openai-agents`. Imports from `agents.extensions.sandbox.runloop` and Runloop exports from `agents.extensions.sandbox`, including `RunloopSandboxClient`, no longer work. Applications that still need Runloop can stay on a previously released compatible version while migrating.
+
+The [Modal example](#modal) uses `ModalSandboxClient` and `ModalSandboxClientOptions` from `agents.extensions.sandbox`. Install `openai-agents[modal]`, configure Modal authentication, and set an app name. Replace the client and options in `SandboxRunConfig`, and adapt provider-specific mounts and platform operations. `ModalCloudBucketMountStrategy` provides native cloud bucket mounts; review and test its provider-specific behavior and credentials for your workload.
+
+Before switching, preserve any data you need from existing Runloop sandboxes. Runloop sandbox IDs, snapshots, and session state are provider-specific; do not assume Modal can resume them. Create a new Modal sandbox and restore the data through a supported mechanism.

-
-Install the repo extra:
-
-```bash
-uv sync --extra runloop
-```
-
-Sign up for Runloop, no credit card required and $50 in credits @ [platform.runloop.ai](https://platform.runloop.ai/).
-Export the required environment variables:

-```bash
-export OPENAI_API_KEY=...
-export RUNLOOP_API_KEY=...

-### Run

-```bash
-uv run python examples/sandbox/extensions/runloop/runner.py --stream

-- `--blueprint-name <name>`
-- `--pause-on-exit`

-`managed_secrets` are stored as Runloop account secrets and only secret references are persisted in session state. An entry's value may instead be `RunloopExistingSecret()`, which attaches a secret that is already stored on the account by name, uploading nothing and leaving the stored value untouched. The platform facade also exposes Runloop-native helpers for blueprints, benchmarks, secrets, network policies, and axons.
-
-If you enable `--root`, Runloop launches the devbox with `launch_parameters.user_parameters={"username":"root","uid":0}`. In that mode, the default home and working directory become `/root`, so the example also uses `/root` as its manifest workspace root. If you configure root launch in your own code, either rely on that root-mode default or explicitly choose a `manifest.root` under `/root`.
