# Runtime Hooks
URL: /docs/api-reference/hooks/runtimes

Hooks for creating assistant runtimes.

Runtime hooks create the `AssistantRuntime` passed to `AssistantRuntimeProvider`.

```tsx
import {
  AssistantRuntimeProvider,
  useLocalRuntime,
} from "@assistant-ui/react";

function App() {
  const runtime = useLocalRuntime(chatModelAdapter);

  return (
    <AssistantRuntimeProvider runtime={runtime}>
      {children}
    </AssistantRuntimeProvider>
  );
}
```

## Core Runtime Hooks \[#core-runtime-hooks]

* [`useRemoteThreadListRuntime`](/docs/runtimes/concepts/threads) adds backend-backed thread list management.
* [`useExternalStoreRuntime`](/docs/runtimes/custom/external-store) adapts an external message store.
* [`useAssistantTransportRuntime`](/docs/runtimes/custom/assistant-transport) consumes assistant-stream transport events.

## Integration Runtime Hooks \[#integration-runtime-hooks]

* [`useChatRuntime`](/docs/runtimes/ai-sdk/overview) adapts AI SDK chat helpers.
* [`useDataStreamRuntime`](/docs/runtimes/custom/data-stream) adapts assistant-stream data streams.
* [`useLangGraphRuntime`](/docs/runtimes/langgraph/overview) adapts LangGraph.
* [`useCloudThreadListRuntime`](/docs/cloud) uses Assistant Cloud for thread persistence.

## Runtime Options \[#runtime-options]

Most runtime hooks accept adapters for persistence, attachments, speech, dictation, feedback, and suggestions. See [Adapters](/docs/api-reference/adapters) for the adapter map.
