# Grok

> xAI's Grok: conversational, with a real-time bent.

Grok is xAI's family of models: conversational, quick, and tuned for a more
direct style. A good pick for chat-first products and up-to-the-minute topics.

## Best for

* Conversational assistants with a distinctive voice.
* Current-events and real-time-leaning questions.
* Fast, general-purpose chat.

| **Endpoint**         | `POST /chat/completions`        |

  ```python Python theme={null}
  from openai import OpenAI
  client = OpenAI(base_url="https://api.heyaskr.ai", api_key="ASKR_API_KEY")

  resp = client.chat.completions.create(
      model="grok-4",
      messages=[

## Pricing

Priced per token, input and output separately. As a rough guide, expect around
**\$3 per 1M input tokens** and **\$15 per 1M output tokens** for the flagship
model.
