# Grok 4.1 Fast Non-Reasoning

> Grok 4.1 Fast Non-Reasoning by xAI via Anyfast OpenAI-compatible API. Grok 4.1 without reasoning.

Grok 4.1 Fast Non-Reasoning is available through Anyfast via an OpenAI-compatible interface. Grok 4.1 without reasoning.

## Key capabilities

* **OpenAI-compatible** — Works as a drop-in replacement with the OpenAI SDK
* **Streaming** — Supports real-time token streaming via SSE
* **Strong reasoning** — Designed for complex, multi-step tasks

## Quick example

<CodeGroup>
  ```bash cURL theme={null}
  curl https://www.anyfast.ai/v1/chat/completions \
    -H "Authorization: Bearer YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "model": "grok-4-1-fast-non-reasoning",
      "messages": [
        { "role": "user", "content": "Explain quantum entanglement in simple terms." }
      ]
    }'
  ```

  ```python Python theme={null}
  from openai import OpenAI

  client = OpenAI(
      api_key="YOUR_API_KEY",
      base_url="https://www.anyfast.ai/v1"
  )

  response = client.chat.completions.create(
      model="grok-4-1-fast-non-reasoning",
      messages=[
          {"role": "user", "content": "Explain quantum entanglement in simple terms."}
      ]
  )

  print(response.choices[0].message.content)
  ```
