# Workflow\.sleep()

The `.sleep()` method pauses execution for a specified number of milliseconds. It accepts either a static number or a callback function for dynamic delays.

## Usage example

```typescript
workflow.sleep(5000);
```

## Parameters

**milliseconds:** (`number | ((context: { inputData: any }) => number | Promise<number>)`): The number of milliseconds to pause execution, or a callback that returns the delay

## Returns

**workflow:** (`Workflow`): The workflow instance for method chaining

## Extended usage example

```typescript
import { createWorkflow, createStep } from "@mastra/core/workflows";

const step1 = createStep({...});
const step2 = createStep({...});

export const testWorkflow = createWorkflow({...})
  .then(step1)
  .sleep(async ({ inputData }) => {
    const { delayInMs } = inputData;
    return delayInMs;
  })
  .then(step2)
  .commit();
```
