# Grok

> Using xAI Grok models with Upsonic

## Overview

xAI provides Grok models with real-time information access, strong reasoning capabilities, and multimodal understanding. All Grok models have built-in web search.

**Model Class:** `OpenAIChatModel` (OpenAI-compatible API)

## Authentication

```bash theme={null}
export GROK_API_KEY="xai-..."
```

## Examples

```python theme={null}
from upsonic import Agent, Task
from upsonic.models.grok import GrokModel

model = GrokModel(model_name="grok-4")

agent = Agent(model=model)

task = Task("Hello, how are you?")
result = agent.do(task)
print(result)
```

## Model Settings

You can set model parameters in two ways: on the model or on the Agent.

**On the model:**

```python theme={null}
from upsonic import Agent, Task
from upsonic.models.grok import GrokModel, GrokModelSettings

model = GrokModel(
    model_name="grok-4",
    settings=GrokModelSettings(max_tokens=1024, temperature=0.7)
)
agent = Agent(model=model)
```

**On the Agent:**

```python theme={null}
from upsonic import Agent, Task
from upsonic.models.grok import GrokModelSettings

agent = Agent(
    model="grok/grok-4",
    settings=GrokModelSettings(max_tokens=1024)
)
```
