# Agent.getDefaultStreamOptionsLegacy()

> **Warning:** **Deprecated**: This method is deprecated and only works with V1 models. For V2 models, use the new [`.getDefaultOptions()`](https://mastra.ai/reference/agents/getDefaultOptions) method instead.

Agents can be configured with default streaming options for memory usage, output format, and iteration steps. The `.getDefaultStreamOptionsLegacy()` method returns these defaults, resolving them if they are functions. These options apply to all `streamLegacy()` calls unless overridden and are useful for inspecting an agent’s unknown defaults.

## Usage example

```typescript
await agent.getDefaultStreamOptionsLegacy();
```

## Parameters

**options?:** (`{ requestContext?: RequestContext }`): Optional configuration object containing request context. (Default: `{}`)

## Returns

**defaultOptions:** (`AgentStreamOptions | Promise<AgentStreamOptions>`): The default vNext streaming options configured for the agent, either as a direct object or a promise that resolves to the options.

## Extended usage example

```typescript
await agent.getDefaultStreamOptionsLegacy({
  requestContext: new RequestContext(),
});
```

### Options parameters

**requestContext?:** (`RequestContext`): Request Context for dependency injection and contextual information. (Default: `new RequestContext()`)
