​
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

export GROK_API_KEY="xai-..."

​
Examples

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: 
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: 
from upsonic import Agent, Task
from upsonic.models.grok import GrokModelSettings

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