# CascadeResult

> Result dataclass from cascade execution — content, cost breakdown, quality diagnostics, timing, and tool calls.

# CascadeResult

Returned by `CascadeAgent.run()`, `run_streaming()`, and `run_batch()`. Contains the generated response along with full cost, quality, timing, and routing diagnostics.

## Usage

```python theme={null}
result = await agent.run("Explain quantum computing")

print(result.content)
print(f"Model: {result.model_used}")
print(f"Cost: ${result.total_cost:.6f}")
print(f"Savings: {result.savings_percentage}%")
print(f"Cascaded: {result.cascaded}, Accepted: {result.draft_accepted}")
```

## Methods

### `to_dict()`

Convert the result to a plain dictionary.

```python theme={null}
data = result.to_dict()
import json
print(json.dumps(data, indent=2))
```
