Grok is a family of Large Language Models (LLMs) developed by xAI.
Inspired by the Hitchhiker's Guide to the Galaxy, Grok is a maximally truth-seeking AI that provides insightful, unfiltered truths about the universe.
xAI offers an API for developers to programmatically interact with our Grok models. The same models power our consumer facing services such as Grok.com, the iOS and Android apps, as well as Grok in X experience.
If you want to use a regional endpoint, you need to specify the endpoint url when making request with SDK. In xAI SDK, this is specified through the api_host parameter.
Is not free models available for xAI A.P.I.
See this example from the official website:
import os
from xai_sdk import Client
from xai_sdk.chat import user
client = Client(
api_key=os.getenv("XAI_API_KEY"),
api_host="us-east-1.api.x.ai" # Without the https://
)
chat = client.chat.create(model="grok-4")
chat.append(user("What is the meaning of life?"))
completion = chat.sample()
