xAI is a platform for providing endpoints for Large Language models. See their list of models here.

We recommend experimenting to find the best-suited model for your use-case. The grok-3 model is good for most use-cases.

Authentication

Set your XAI_API_KEY environment variable. You can get one from xAI here.

export XAI_API_KEY=sk-***

Example

Use xAI with your Agent:


from agno.agent import Agent
from agno.models.xai import xAI

agent = Agent(
    model=xAI(id="grok-3"),
    markdown=True
)

agent.print_response("Share a 2 sentence horror story.")

xAI models support live search capabilities that can access real-time information:

from agno.agent import Agent
from agno.models.xai import xAI

agent = Agent(
    model=xAI(
        id="grok-3",
        search_parameters={
            "mode": "on",
            "max_search_results": 20,
            "return_citations": True,
        },
    ),
    markdown=True,
)

agent.print_response("What's the latest news about AI developments?")
