Is Grok AI Free? What You Get on the Free Plan in 2026

Yes, Grok AI is free. You can use it at grok.com or inside X with no credit card and no subscription, and xAI has kept a real free tier rather than a short trial. The catch is the ceiling, and it is not the one most guides quote. xAI does not publish a free-tier number, and the widely repeated 10 prompts every 2 hours figure comes from a limit system it retired in June 2026. What is confirmed is that the free plan runs Grok’s Fast mode, while the Expert and Heavy modes, now on Grok 4.7, need a paid plan. Since October 12, 2026 that paid plan is The X Subscription, and its pricing grid lists a limited free image allowance again.

So the real question is not whether Grok is free, but whether the free tier is enough for you. This guide covers exactly what the free plan includes, how the limits actually work now that paid plans run on a shared weekly pool, which model you actually get, why xAI gives Grok away, and when it makes sense to pay. If you just want to test Grok or ask casual questions, the free tier handles more than you might expect.

The Key Takeaways

• Grok is free on grok.com and X with no credit card required to start.
• xAI publishes no free-tier message limit. The per-2-hour caps other guides quote were retired in June 2026; check Settings > Usage for your real position.
• Free access runs Grok’s Fast mode. Auto, Expert and Heavy all ask you to upgrade, and Expert and Heavy are the only modes xAI puts a model name on: Grok 4.7.
• Free images are back in a limited form: xAI removed them in March 2026, and its October pricing grid lists image generation as “Limited” on Free. Video still needs Premium ($30).
• Since October 12, 2026, paid access is The X Subscription: Plus $8/month, Premium $30, Super $100 and Ultra $200, replacing the SuperGrok tiers.

Is Grok AI Free to Use in 2026?

Grok AI is free to use in 2026, and you do not need an X Premium subscription to try it. You can open grok.com, sign in, and start chatting without entering any payment details, or use Grok directly inside the X app. You can also chat logged out in Fast mode, and our guide to using Grok without an account explains what that means for your privacy. The free tier is aimed at casual users and anyone who wants to see what Elon Musk’s chatbot can do before paying.

What changed recently is what the free plan covers, not whether it exists. In March 2026 xAI removed free image generation entirely. Since The X Subscription launched on October 12, 2026, xAI’s pricing grid lists limited Chat, limited image generation and limited Grok Build on the free tier, plus Cursor’s coding agent, while video, Grok Bot and API access sit behind the paid tiers.

The one honest caveat is usage. Free access is metered, so you get a set number of prompts in each window rather than unlimited chatting. For light use that limit rarely gets in the way, but the moment you start a longer task, you will feel it.

Grok Free Tier Limits: How Many Messages Do You Really Get?

Almost every guide answers this with 10 prompts every 2 hours. That number no longer describes anything. In June 2026 xAI replaced per-product limits with one shared weekly usage pool for paid users, and its own documentation confirms the free tier now sits outside that pool with separate Chat and Voice allowances that reset on their own schedule. Our guide to Grok voice mode walks through what that voice side actually does. xAI does not publish what those allowances are.

The one reliable way to see where you stand is Settings > Usage, on web and mobile, which shows a progress bar, a percentage breakdown by product, and your reset date. Two things still eat into the allowance faster. Long back-and-forth conversations burn through it quickly, and demand matters, since xAI can tighten access during peak traffic. Any figure you see quoted elsewhere is either a leftover from the old system or someone else’s screenshot.

Access also depends on where you use it. On X, any account gets limited Grok access with tight caps and lower priority at busy times, while grok.com gives you the same free tier as a standalone chatbot without paying for X. Either way, you are drawing from the same kind of capped free budget.

Which Grok Model Is Free?

Most guides still answer this with Grok 3 or a mini model. Neither is an answer any more. xAI retired the Grok 3 slug from its API on May 15, 2026, and grok.com names no mini model anywhere. What it does name is a mode list, and that is where the real answer sits. Open Grok without a paid plan and the picker defaults to Fast, described only as “quick responses” with no model attached, while Auto, Expert and Heavy are all flagged as needing an upgrade.

Only Expert and Heavy carry a model name, and since October 3, 2026 that name is Grok 4.7, which replaced Grok 4.6 in the Grok app. So what you actually lose on the free plan is not a mystery mini model, it is those two modes and the features that ride on them, including DeepSearch and extended reasoning. The older Grok 4.5 is not free either, and it is no longer what the paid tiers run.

Grok 4.7 shipped on September 21, 2026, six weeks after 4.6, first in Cursor, Grok Build, the API and third-party coding harnesses. According to Grok’s release notes it has powered Expert mode on grok.com since October 3, along with Fast mode for paid subscribers, so paying does get you the newest model now. The free Fast mode still names no model. For most casual chat it is more than enough, and you would only really miss the paid modes on demanding technical or research work.

Is Grok Image Generation Free?

Partly, again. In March 2026, Grok’s image and video generation, including Grok Imagine and the “Spicy” mode, moved behind a paywall across every tier, and the last remnants of free image access were quietly removed, as reported by Calcalist. The pricing grid xAI published with The X Subscription on October 12, 2026 lists image generation as “Limited” on the free tier, so a small free allowance appears to be back. Video generation is not free: it starts at Premium.

If making images is the reason you came to Grok, expect a tight free allowance at best, because xAI does not publish the number and we could not confirm it in the app. Plus at $8/month is the cheapest tier with full image generation, and Premium at $30/month is the cheapest with video. Many older guides still describe the March change and miss the October one.

Why Is Grok AI Free?

Grok is free because xAI treats it as a growth engine for the wider X ecosystem, not a standalone product to paywall from the start. Basic chat pulls users in, keeps them on the platform, and feeds on X’s real-time stream of posts, which xAI says gives Grok a live view of the world that rival models lack.

The money comes from elsewhere. xAI monetizes through paid plans rather than by charging for entry-level chat, as Wikipedia’s Grok overview notes about its bundled access model, and since October 12, 2026 those plans are one bundle: The X Subscription, which ties Grok to X Premium perks and Cursor. Free access is the top of the funnel, and the caps are the nudge toward a paid plan once Grok becomes part of your routine.

Is the Grok Free Plan Enough, or Do You Need to Pay?

For casual use, the free plan is fine. Quick questions, fact checks, light research, and the occasional brainstorm all fit inside the free limits without much friction. If Grok is a “now and then” tool for you, there is no reason to pay.

You start feeling the ceiling when Grok becomes a daily habit. If you run out of free allowance mid-task, want full image generation or video, or need Grok 4.7 reasoning and DeepSearch, that is the signal to upgrade. Since October 12, 2026, Grok’s paid plans are The X Subscription: Plus at $8/month, Premium at $30/month, Super at $100/month and Ultra at $200/month for the largest usage pool xAI sells. The agent app sits on top of that: Grok Bot is included from Premium up, which our guide to what Grok Bot costs and who gets access breaks down in full.

Want Grok Plus Every Other Model? Try Fello AI

Grok’s free tier is useful, but it is still one model from one company with one tight limit and little or no image allowance. Fello AI takes a different route. It ships a Free AI model that is forever free with no message limits, so you can keep asking questions without hitting a wall or watching a meter run. Most free AI tiers quietly cap you after a handful of messages; this one does not. When you want more, one flat $11.99/month covers every frontier model, so you can swap between Grok, ChatGPT, Claude, and Gemini in one chat, generate images, and work with PDFs and documents without juggling separate accounts.

That makes Fello a strong fit for the “I won’t pay for one tool” crowd. You start free on the Free AI model with no meter running, then step up to the full lineup only if you want to, so nothing holds you back when you hit a single model’s wall. If you are still comparing options, our roundup of the best free AI chatbots tests Grok against ChatGPT, Claude, Gemini, and more on real message limits. You can also check whether Gemini is free.

Conclusion

Grok AI is free, it works on both grok.com and X with no credit card, and it stays free for text chat. The real limits are usage on the Fast mode, though not the per-2-hour cap you will read elsewhere, a small image allowance at best, and no free video.

If you keep hitting the cap, Plus at $8/month is the cheapest paid tier of The X Subscription, and Premium at $30/month is the cheapest with video and Grok Bot, with Super at $100 and Ultra at $200 above it. If you already pay for SuperGrok or X Premium, our guide to The X Subscription shows which tier replaces your plan. If you want to avoid single-model limits entirely, a multi-model app like Fello lets you keep going across every major AI at once, with a Free AI model that stays free with no limits. Start there, see how often you still hit the wall, and decide from there. Compare Grok against the field on our best AI models hub. On a Mac, our Grok desktop client guide for macOS shows how to run the free tier as an app.
