What can you use Grok for?
How much does Grok cost?
Grok comes bundled with X Premium and through separate SuperGrok subscriptions on grok.com, including a higher Heavy tier for power users. xAI changes tiers and promotional pricing often, and its pricing page could not be verified for this review, so check grok.com/plans for the current prices before subscribing.
What models power Grok?
Grok 4.5Latest
xAI's first model since acquiring Cursor — built specifically for coding and agentic work, roughly 4x more token-efficient than Claude Opus 4.8 on engineering tasks, at a fraction of the cost.
How to use Grok
- Access Grok through X (Twitter) if you have Premium or Premium+, or directly via grok.com/the Grok app.
- Start a conversation -- Grok can pull in real-time X context when relevant.
- Use image generation directly within the chat for visual requests.
- For coding tasks, use Grok Build or Cursor, where the latest Grok models are integrated.
- Upgrade to a SuperGrok tier via grok.com if you want the latest models outside of X Premium bundling.
Best Grok alternatives
ChatGPT
Broader third-party ecosystem and more mature multimodal features if real-time X context is not a priority.
Claude
Stronger for careful, filtered long-document writing and coding rather than Grok's more irreverent style.
Perplexity AI
A better choice specifically for cited, source-backed research answers.
Is Grok worth it?
Grok stands out for a genuinely distinctive mix of real-time social awareness and personality that most competitors don't attempt, plus coding ability that's improving fast through Grok Build. Where it struggles is pricing clarity -- X Premium bundling versus separate SuperGrok tiers is confusing to navigate -- and its third-party ecosystem is still smaller than OpenAI's or Google's, which can make a more straightforward assistant an easier sell for casual users.
