Elon Musk’s AI company has released another upgrade to its chatbot. Grok 4.7 is now the most capable model in xAI’s lineup, built for coding, research, and agent-style tasks that run across many steps. It arrived with a much larger memory for long documents and is spreading quickly to platforms beyond X. This guide explains what Grok 4.7 is, what changed, how much it costs, where you can use it, and how it compares with rivals like ChatGPT and Gemini.
What Is Grok 4.7?
Grok is the AI assistant developed by xAI, the artificial intelligence company founded by Elon Musk. It is built into X (formerly Twitter) and is also available to developers through an API. Grok 4.7 was released on September 21, 2026. xAI positions it as its strongest model for coding, agentic tasks, and knowledge-heavy work, according to a breakdown of the release published by Basenor.
Grok 4.7 Key Features
500,000-Token Context Window
Grok 4.7 can work with up to 500,000 tokens in a single request. In simple terms, that is enough to read very long reports, several books’ worth of text, or large codebases at once. A bigger context window means the AI can keep more information in mind and give answers that account for the whole document rather than a small piece.
Text and Image Input
You can give Grok 4.7 both text and images. That makes it useful for tasks like explaining a chart, reading a screenshot of an error message, or describing a photo.
Stronger Coding and Agent Tasks
xAI focused this release on programming and multi-step “agent” work, where the AI plans and completes a series of actions rather than answering a single question. Musk said Grok 4.7 handles large code repositories well. He also claimed strong results on legal and accounting tasks, though independent benchmark data for those claims had not been published at the time of writing.
Grok 4.7 Fast
A faster variant called Grok 4.7 Fast exists, but at launch it was available only through the coding tool Cursor and xAI’s Grok Build, not the public API.
Grok 4.7 Pricing
For developers using the xAI API, Grok 4.7 keeps the same pricing as Grok 4.6:
| Prompt size | Input (per 1M tokens) | Output (per 1M tokens) |
|---|---|---|
| Under 200,000 tokens | $2.00 | $6.00 |
| Over 200,000 tokens | $4.00 | $12.00 |
Regular users on X do not pay per token. Access depends on your X account and subscription level, so check X’s current plans for details.
Where Can You Use Grok 4.7?
- On X: Chat with Grok directly in the X app or website. No developer account is needed.
- xAI API: Paid API tiers offer longer context, higher limits, and integration with your own tools.
- Google’s Gemini Enterprise Agent Platform: Added in early October 2026 for business users.
- Microsoft Foundry: Available from October 7, 2026, for developers building on Microsoft’s platform.
- Ramp Router and Cursor: Third-party tools that route requests to different models.
Tip: Older conversations on X may not use the newest model. Start a new chat to make sure you are on Grok 4.7.
Is Grok 4.7 in Tesla Cars?
Not yet. Grok has appeared in some Tesla vehicles in earlier versions, but no in-car rollout of Grok 4.7 had been announced. For now, the upgrade applies to X and the xAI API. Tesla’s bigger AI focus at the moment is its Optimus robot; see our guide to Tesla Optimus robot production.
Grok 4.7 vs ChatGPT vs Gemini
| Assistant | Strengths | Best for |
|---|---|---|
| Grok 4.7 | Huge context window, real-time X data, coding | News trends, long documents, developers |
| ChatGPT (GPT-6) | Strong reasoning, Intelligent UI, wide app support | General use, writing, coding |
| Gemini | Deep Google Docs, Gmail, and Drive integration | Google users, documents, productivity |

How to Use Grok 4.7 Effectively
- Use its memory. Paste long documents or code and ask questions about the whole thing.
- Ask for sources. When asking about news, request links so you can verify details.
- Be specific. State the format you want: summary, table, step list, or code.
- Check important facts. Like every AI, Grok can make mistakes, especially on fast-moving news.
- Protect your privacy. Avoid sharing passwords, card numbers, or personal addresses in any AI chat.
Concerns and Controversies
Grok has faced criticism over safety. In October 2026, a policy leader from Musk’s AI business was questioned by the New York City Council about Grok’s safeguards, including concerns about sexualized images. There have also been reports of AI agents exposing personal information when given broad access to accounts. These stories are a reminder to use AI assistants carefully, especially when you connect them to shopping, payment, or personal data.
Who Should Use Grok 4.7?
- Developers working with large codebases who want a long-context model at a moderate price.
- Researchers and analysts who need to process long reports.
- X users who want quick explanations of trending topics.
- Businesses already using Microsoft Foundry or Gemini Enterprise who want another model option.
What Grok 4.7 Means for the AI Race
The release shows how fast the competition has become. Within a few weeks in late 2026, OpenAI launched GPT-6 models, Google pushed Gemini 4 Argon to paid users, Anthropic updated Claude, and xAI shipped Grok 4.7. For users, this race means better tools at lower prices. Grok’s distinct angles are its very large context window and its connection to real-time conversations on X, which can make it quick on breaking topics. The trade-off is that information from social media still needs careful checking. Expect more frequent updates from every company, and expect each one to claim the top spot on some benchmark. The smart approach is to test the tools on your own real tasks.
Example Tasks to Try With Grok 4.7
If you are new to Grok, these practical tasks show what the new model does well:
- Summarize a long report: Paste a 50-page PDF’s text and ask for a one-page summary with the five most important findings.
- Explain an error: Upload a screenshot of an error message and ask what caused it and how to fix it.
- Review code: Share several files from a project and ask Grok to find bugs or suggest cleaner structure.
- Compare documents: Paste two contracts or policies and ask for a table of differences.
- Catch up on a trend: Ask what people on X are saying about a tech launch, then request links to original posts so you can verify.
Start small, check the results, and build up to longer tasks once you trust how Grok handles your type of work.
