Grok 4.7

Grok 4.7 is SpaceXAI's frontier model built for coding, agentic tasks, and knowledge work.

If you already have an API key, set the model name to grok-4.7:

import os
from xai_sdk import Client
from xai_sdk.chat import user

client = Client(api_key=os.getenv("XAI_API_KEY"))

chat = client.chat.create(model="grok-4.7")
chat.append(user("Find and fix the bug, then explain it: function median(a){a.sort();return a[a.length/2]}"))

response = chat.sample()
print(response.content)

import { xai } from '@ai-sdk/xai';
import { generateText } from 'ai';

const { text } = await generateText({
  model: xai.responses('grok-4.7'),
  prompt:
    'Find and fix the bug, then explain it: function median(a){a.sort();return a[a.length/2]}',
});

console.log(text);

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: process.env.XAI_API_KEY,
  baseURL: 'https://api.x.ai/v1',
});

const response = await client.responses.create({
  model: 'grok-4.7',
  input: [
    {
      role: 'user',
      content:
        'Find and fix the bug, then explain it: function median(a){a.sort();return a[a.length/2]}',
    },
  ],
});

console.log(response.output_text);

curl https://api.x.ai/v1/responses \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $XAI_API_KEY" \
  -d '{
    "model": "grok-4.7",
    "input": "Find and fix the bug, then explain it: function median(a){a.sort();return a[a.length/2]}"
  }'

Rate limits and live pricing for your team are on the model detail page and Pricing.

• We highly recommend setting a prompt_cache_key (Responses API; x-grok-conv-id header on Chat Completions). It routes a conversation's requests to the same server, making cache hits reliable; without it you often pay full input price on a cache-cold server. See What Breaks Caching for common mistakes.
• Long agent loops additionally benefit from context compaction; for tool-heavy workloads see function calling.
• Encrypted reasoning is always returned on the Responses API. POST /v1/responses responses from grok-4.7 include reasoning.encrypted_content even when include does not list it, so multi-turn conversations keep the model's reasoning without extra configuration. Pass the reasoning items back unchanged in the next request's input; see Encrypted reasoning content. Chat Completions is unchanged.

Grok 4.7 Fast is the same model served on faster infrastructure, billed at twice the standard token rates. It is available only in Cursor and Grok Build, and it is not included in Grok Build's free tier. It is not available on the public xAI API. Rates are on the Pricing page.

• xAI API: get a key from the console
• US regional endpoint: also served at https://us.api.x.ai/v1, which keeps inference in the United States, with token usage priced at a 10% premium; see Regional Endpoints
• Grok Build: the default model of the coding agent
• Cursor: available on all plans
• Model gateways: OpenRouter, Vercel, and Cloudflare

• Reasoning - controlling reasoning_effort, including "xhigh"
• Announcement - launch post with demos and full benchmark figures
• Models - compare available models and their capabilities
• Pricing - token pricing for all models
