What is Grok? 5 plans for xAI's assistant, latest model 2026

Grok is the AI assistant built by xAI. You can ask questions, search for current news, create images and video, and write code on grok.com, in the mobile apps, or inside X. The free tier works on its own, and paid plans raise limits and add features.

Grok is xAI's AI assistant, and xAI is now part of SpaceX

As of Oct 27, 2026, the Grok page on x.ai describes Grok as one place to chat, search, reason, and create. Grok can search the web and X in real time and cite its sources.

xAI first announced Grok on Nov 3, 2023. On Feb 2, 2026, xAI posted that SpaceX had acquired xAI. That is why x.ai is now signed SpaceXSI, and the copyright line at the bottom of each page names the legal entity as SpaceXAI LLC.

The product page also lists Multi-agent mode, where several agents work in parallel, Grok Imagine for images and video, voice chat, PDF reading and more than 30 languages.

Use Grok on grok.com, in the mobile apps, or right inside X

The x.ai/grok page lists three steps: open grok.com on a computer or install the iOS or Android app, sign in with your X account or email, then start asking. Your chat history syncs across devices.

The third way is Grok inside X. The X Help Center says Grok is on X for iOS, Android and web, in every country where X is available. Grok on X can decide on its own to search public X posts or the web to answer you.

If you already pay for X Premium, the X Premium page says Premium raises your Grok usage limits, and Premium+ includes SuperGrok access and Grok Bot. Since Oct 12, 2026, X Premium has been part of The X Subscription. Existing X Premium subscribers keep their plan, price and features until they choose to switch.

Grok 4.7 is the latest model as of October 2026

The xAI news page shows a fast release pace in 2026. Grok 4.5 launched on Jul 16 and reached grok.com, X and the apps on Jul 22. Grok 4.6 followed on Aug 12, with a focus on long-running agents and visual work.

The newest is Grok 4.7, announced on Sep 21, 2026. The company calls it its most powerful model for coding and knowledge work. Grok 4.7 uses a new, larger base model than Grok 4.6 and checks its own work more carefully. For developers, API pricing starts at $2 per million input tokens and $6 per million output tokens.

As of Oct 27, 2026, the official news list has no post announcing Grok 5.

What can free Grok do, and when should you pay?

On Oct 12, 2026, xAI introduced The X Subscription, which puts Grok, Grok Bot, Cursor and X Premium in one plan. As of Oct 27, 2026, the pricing page lists five individual plans: Free at $0, Plus at $8, Premium at $30, Super at $100, and Ultra at $200 per month. Prices exclude taxes and fees such as VAT.

Free gives you chat, Imagine image generation, and Grok Build, the coding tool, within limits. Plus opens full Chat, Voice, Imagine and Build, plus Grok API access. Premium gives 4x the usage of Plus and adds Grok Bot, the latest Grok models, and video generation. Super gives 15x Plus usage and priority access at peak times; Ultra gives 50x Plus.

The comparison table is more precise. Video generation and Grok Bot start at Premium; Free and Plus have neither. Free also has no Grok API access. Beyond individual plans, the table lists Teams from $30 per user per month and Enterprise with custom pricing.

If you already pay for SuperGrok, the announcement says you can keep your plan, price and features, or switch and get a prorated refund for the old plan. According to the same post, Premium includes the benefits of SuperGrok, Cursor Pro and X Premium+, which previously cost $90 per month combined.

A quick way to choose: Free if you mostly ask questions, follow news on X and make a few images; Plus if you often hit limits or want Grok API access; Premium if you need video or Grok Bot.

Outside the US, check your local App Store price before you subscribe

App Store prices are set per country, so they can differ from the USD prices on x.ai. In Vietnam, for example, the Grok app on the Vietnam App Store is free, lists X Corp. as the provider, supports English and 38 more languages, and carries a 16+ age rating.

As of Oct 27, 2026, its in-app purchase list still uses the old SuperGrok names rather than The X Subscription plans on the web: SuperGrok Lite at 299,000 VND, SuperGrok at 799,000 VND (with a second SuperGrok item at 7,999,000 VND), SuperGrok Plus at 2,999,000 VND, and SuperGrok Heavy at 7,999,000 VND. It also sells Extra Usage Credits from 149,000 VND. The store page does not state the billing period for each item, so confirm the renewal cycle on the purchase screen before you tap buy.

On age, the Consumer FAQs say users must be at least 13, and users aged 13 to 17 need a parent or guardian's permission. Parents should also note the 16+ App Store rating when a child has their own phone.

Turn off training and read the content rules before you rely on Grok

The SpaceXSI Consumer FAQs say the company may use your prompts and Grok's replies to train its models. You can choose. In the app, go to Settings, Data Controls, and turn off Improve the Model. On grok.com, go to Settings, Data, and turn off Improve the Model.

For a private conversation, tap the ghost icon in the top right corner to open Private Chat. These chats stay out of your history, are not used for training, and are deleted within 30 days. The company still advises against putting personal or sensitive information in your prompts.

If you use Grok on X, the X Help Center gives the path: Settings, Privacy & Safety, Data sharing and personalization, Grok & Third-party Collaborators. There you can turn off data sharing and delete your conversation history.

On content, the Acceptable Use Policy bans undressing or sexualizing real people, impersonating real people, and any sexual content involving children. It also bans any attempt to get around the system's safeguards. X warns that Grok may give wrong answers with confidence, so check anything important yourself.
