Description
Grok is xAI’s AI chatbot, built by Elon Musk’s AI company with real-time search of the web and X built directly into the chat experience. The Free plan includes live web and X search, voice mode, and Connectors at no cost. SuperGrok, the standard paid plan, unlocks the Grok 4 model, higher rate limits across every feature, Expert mode, and image and video generation. xAI also sells SuperGrok Lite and SuperGrok Heavy as separate tiers above and below standard SuperGrok, plus a Business plan for teams and a custom-quoted Enterprise plan with SSO, SCIM, and dedicated infrastructure. Grok is also reachable through X’s own Premium and Premium+ subscriptions, a separate purchase path from xAI’s SuperGrok plans that bundles some of the same model access alongside X’s platform features. Developers can access Grok models directly through the pay-per-token xAI API. It suits people who want a chatbot with live awareness of X and the web built into its core, alongside standard chat, coding, and reasoning tasks.
Key Features
- Real-time web and X search — included even on the Free plan, pulling live information into chat responses.
- Grok 4 model — SuperGrok’s frontier model, replacing the more limited model available on Free.
- Voice mode — conversational voice interaction included from the Free tier upward.
- Image and video generation — included on SuperGrok, not the Free plan.
- Connectors — links external tools and data sources into a Grok conversation, available on both Free and SuperGrok.
- Expert mode — a SuperGrok-exclusive capability for deeper, more thorough responses.
- Enterprise security controls — SSO, SCIM, custom data retention, and dedicated infrastructure available on Business and Enterprise.
How It Works
Grok is used through the web at grok.com, native iOS and Android apps, or directly inside X. The Free plan gives access to real-time web and X search, voice mode, and Connectors within generous but unspecified usage limits. Upgrading to SuperGrok unlocks the Grok 4 model, higher rate limits across every feature, Expert mode, and image and video generation. xAI also sells SuperGrok Lite as a lower-cost entry tier and SuperGrok Heavy as a higher tier above standard SuperGrok, alongside a separate Business plan for teams needing seat management and consolidated billing. Grok is also reachable through X’s own Premium and Premium+ subscriptions, a separate purchase path through X rather than xAI directly, which bundles some Grok access alongside X’s own platform features like ad-free browsing. Organizations needing SSO, custom data retention, or dedicated infrastructure move to the custom-quoted Enterprise plan instead of a self-serve tier.
Technical Architecture & Overview
- Core Engine: Grok 4 on SuperGrok and above; the Free plan uses a more limited model, per xAI’s own plan comparison.
- Deployment: Web app, native iOS and Android apps, direct integration inside X, and a separate Grok Build CLI for developers.
- API Surface: xAI API billed per million tokens by model, separate from consumer subscriptions; Grok 4.5 is priced at $2 per million input tokens and $6 per million output tokens, per xAI’s own announcement.
- Known Limits: Free plan usage limits are described only as “generous” rather than a fixed published number; SuperGrok Lite and SuperGrok Heavy pricing did not render as a static figure on xAI’s own pricing page at the time of this check.
Pros & Cons
| Pros | Cons |
|---|---|
| Real-time web and X search is included even on the Free plan, not reserved for a paid tier | SuperGrok Lite and SuperGrok Heavy prices are not listed as static figures on xAI’s official pricing page |
| SOC 2 compliance (Type I and II) is listed on both Free and SuperGrok, not just Enterprise | Grok’s Premium/Premium+ access through X is a separate purchase path from SuperGrok, which can create confusion about which subscription unlocks which features |
| Grok is reachable through three separate paths (xAI directly, X’s Premium subscriptions, and the API), giving flexibility in how it’s accessed | Free plan usage limits are not published as a specific number |
| Business and Enterprise tiers add genuine admin controls (SSO, SCIM, custom data retention, dedicated infrastructure) | Enterprise pricing is entirely custom-quoted, requiring direct sales contact |
| Grok Build CLI extends Grok into a developer coding-agent context, not just chat | Newer capabilities roll out to SuperGrok in stages rather than to all subscribers simultaneously, per xAI’s own product announcements |

Frequently Asked Questions
Is Grok free to use?
Yes. The Free plan costs $0 per month and includes real-time web and X search, voice mode, and Connectors, according to xAI’s official pricing page.
What is the difference between Grok’s Free plan and SuperGrok?
SuperGrok adds the Grok 4 model, higher rate limits across every feature, Expert mode, and image and video generation, none of which are included on the Free plan, per xAI’s official plan comparison.
Is Grok the same as X Premium?
No. SuperGrok is purchased directly from xAI, while X Premium and Premium+ are separate subscriptions through X that bundle some Grok access alongside X’s own platform features like ad-free browsing.
How much do SuperGrok Lite and SuperGrok Heavy cost?
Neither price rendered as a static figure on xAI’s official pricing page at the time of this check; both appear in the plan comparison table without a confirmed public rate, so checking the live page directly is the reliable way to confirm current pricing.
How does Grok differ from ChatGPT?
Grok is built around real-time web and X search available from its Free plan, while ChatGPT’s free tier does not include the same live-search integration with a social platform, relying instead on its own separate browsing feature.
