- **Streaming Support** - Real-time response streaming with full event handling
- **Hybrid Tool Usage** - Combine xAI server-side tools with Strands client-side tools
- **Multi-Turn Context** - Seamless conversation history with encrypted content preservation
- **Type Safe** - Full type hints and mypy support

## Requirements

- Python 3.10+
- Strands Agents SDK 1.23.0+
- xAI API key from [xAI Console](https://console.x.ai/)

## Installation

```bash
pip install strands-agents strands-xai
```

## Quick Start

### Basic Usage

```python
from strands_xai import xAIModel
from strands import Agent

# Initialize xAI model
model = xAIModel(
    client_args={"api_key": "your-xai-api-key"},  # or set XAI_API_KEY env var
    model_id="grok-4-1-fast-non-reasoning-latest",
)

# Create an agent
agent = Agent(model=model)

# Use the agent
result = agent("What is the capital of France?")
print(result)
```

### With Streaming

```python
from strands_xai import xAIModel
from strands import Agent
from strands.handlers.callback_handler import PrintingCallbackHandler

model = xAIModel(
    client_args={"api_key": "your-xai-api-key"},
    model_id="grok-4-1-fast-non-reasoning-latest",
)

# Streaming happens automatically with callback handlers
agent = Agent(
    model=model,
    callback_handler=PrintingCallbackHandler()
)

# Text streams to console in real-time
result = agent("Tell me a story")
```

### With Server-Side Tools

```python
from strands_xai import xAIModel
from strands import Agent
from xai_sdk.tools import x_search, web_search

# Use xAI's built-in tools (executed on xAI servers)
model = xAIModel(
    client_args={"api_key": "your-xai-api-key"},
    model_id="grok-4-1-fast-non-reasoning-latest",
    xai_tools=[x_search(), web_search()],
)

agent = Agent(model=model)
result = agent("What are people saying about AI on X?")
print(result)
```

### With Reasoning (grok-3-mini)

```python
from strands_xai import xAIModel
from strands import Agent

# Enable visible reasoning
model = xAIModel(
    client_args={"api_key": "your-xai-api-key"},
    model_id="grok-3-mini",
    reasoning_effort="high",  # "low" or "high"
)

agent = Agent(model=model)
result = agent("Solve this logic puzzle: If all roses are flowers...")
print(result)
```

### With Encrypted Reasoning (grok-4)

For multi-turn conversations with reasoning preserved:

```python
from strands_xai import xAIModel
from strands import Agent

model = xAIModel(
    client_args={"api_key": "your-xai-api-key"},
    model_id="grok-4-fast-reasoning",
    use_encrypted_content=True,  # Preserves reasoning across turns
)

agent = Agent(model=model)

# First turn
result1 = agent("Think through this problem: 2+2")
print(result1)

# Second turn - reasoning context preserved
result2 = agent("Now multiply that by 3")
print(result2)
```

### With Inline Citations

Get sources cited directly in responses:

```python
from strands_xai import xAIModel
from strands import Agent
from xai_sdk.tools import web_search

model = xAIModel(
    client_args={"api_key": "your-xai-api-key"},
    model_id="grok-4-1-fast-non-reasoning-latest",
    xai_tools=[web_search()],
    include=["inline_citations"],  # Enable citations
)

agent = Agent(
    model=model,
    system_prompt="You are a helpful assistant. Always cite sources."
)

result = agent("What are the latest developments in AI?")
print(result)
# Output includes inline citations like [1], [2] with source URLs
```

### Hybrid: Server-Side + Client-Side Tools

```python
from strands_xai import xAIModel
from strands import Agent, tool
from xai_sdk.tools import x_search

@tool
def get_weather(city: str) -> str:
    """Get weather for a city."""
    return f"Weather in {city}: Sunny, 22°C"

# Combine xAI tools with Strands tools
model = xAIModel(
    client_args={"api_key": "your-xai-api-key"},
    model_id="grok-4-1-fast-non-reasoning-latest",
    xai_tools=[x_search()],
)

agent = Agent(model=model, tools=[get_weather])
result = agent("What's the weather in Paris and what are people tweeting about it?")
print(result)
```

## Server-Side Tools

xAI provides built-in tools executed on their infrastructure:

### Available Tools

- **`web_search()`** - Search the web for current information
- **`x_search()`** - Search X (Twitter) for posts and trends  
- **`code_execution()`** - Execute Python code safely

### Basic Usage

```python
from strands_xai import xAIModel
from strands import Agent
from xai_sdk.tools import web_search, x_search, code_execution

model = xAIModel(
    client_args={"api_key": "your-xai-api-key"},
    model_id="grok-4-1-fast-non-reasoning-latest",
    xai_tools=[web_search(), x_search(), code_execution()],
)

agent = Agent(model=model)
result = agent("What's trending on X about AI?")
```

### Combining with Client-Side Tools

Mix xAI server-side tools with your own Strands tools:

```python
from strands_xai import xAIModel
from strands import Agent, tool
from xai_sdk.tools import x_search

@tool
def get_weather(city: str) -> str:
    """Get weather for a city."""
    return f"Weather in {city}: Sunny, 22°C"

model = xAIModel(
    client_args={"api_key": "your-xai-api-key"},
    model_id="grok-4-1-fast-non-reasoning-latest",
    xai_tools=[x_search()],  # Server-side
)

agent = Agent(
    model=model,
    tools=[get_weather]  # Client-side
)

# Agent can use both types of tools
result = agent("What's the weather in Paris and what are people saying about it on X?")
```

## Examples

See the [examples](examples/) directory for complete working examples.
