Paid vs. Free Accounts
X offers three subscription levels, each with different features and pricing.
- Free users get basic access to both with strict limits (e.g., ~10 messages/2 hours; minimal image/video generation).
- X Premium+ ($40/month) unlocks higher quotas, priority processing, early features (like Grok 4.20 Beta), seamless post-enhancement tools on X (xAI button for tones/personality), plus X perks (ad-free, reply boosts).
- Standalone SuperGrok (~$30/month via grok.com or the Grok app) focuses on pure AI power: unlimited-ish queries, full access to advanced models, enhanced Grok Imagine (more/higher-quality images/videos and audio), voice mode, and peak-time priority—without X social features. X Premium+ often delivers the best all-in-one value for active X users, while SuperGrok suits heavy AI creators needing max creative tools.
- On X (x.com/X app): The Free tier has basic limits; X Premium+ ($40/mo) offers the highest quotas on X, early access to features, integrated post tools, and bundled SuperGrok-level AI.
- Standalone (grok.com web + Grok iOS/Android apps): Free tier for limited testing; SuperGrok (~$30/mo) for unlimited-ish queries, full advanced models, enhanced Grok Imagine (higher quotas for images/videos/audio), voice mode, priority, and pure AI focus without X perks. Free basic access is more widely available now (e.g., grok.com), though capped.
In contrast, the free version of X does not include these exclusive features, limiting users to standard functionalities without the additional perks or customization options. However, look at all you get for $395/year.
Note: Grok 4.20 Beta is available to free users on Grok.com and apps for many features; Premium+ or SuperGrok for unlimited access and advanced modes.
➡️ Download the latest Grok app (iOS/Android) for new Imagine UI, voice mode, and instant enhancements.
