# AWS Bedrock

[AWS Bedrock](https://aws.amazon.com/bedrock/) provides realtime speech-to-speech using Amazon Nova models with automatic session management. The plugin handles Nova's 8-minute connection limit transparently, reconnecting during silence to ensure uninterrupted conversations.

<Info>
  Vision Agents requires a [Stream](https://getstream.io/try-for-free/) account
  for real-time transport. Most providers offer free tiers to get started.

## Installation

```sh theme={null}
uv add "vision-agents[aws]"
```

## Quick Start

```python theme={null}
from vision_agents.core import Agent, User
from vision_agents.plugins import aws, getstream

agent = Agent(
    edge=getstream.Edge(),
    agent_user=User(name="Assistant", id="agent"),
    instructions="You are a helpful assistant.",
    llm=aws.Realtime(),
)
```

## Automatic Reconnection

AWS Bedrock has an 8-minute connection limit. The plugin handles this automatically:

* After 5 minutes of silence (configurable via `reconnect_after_minutes`), reconnects during a moment of silence
* After 7 minutes, forces reconnect regardless of audio activity

This ensures uninterrupted conversations without manual intervention.

## Voice Activity Detection

The plugin uses Silero VAD to track audio activity for optimal reconnection timing.

## Function Calling

```python theme={null}
@agent.llm.register_function(description="Get weather for a location")
async def get_weather(location: str) -> dict:
    return {"city": location, "temperature": 72, "condition": "Sunny"}
```

See the [Function Calling guide](/guides/mcp-tool-calling) for details.
