Is Grok AI free?
Partly. xAI's current pricing lists a $0 Free plan for Grok with web/X search and voice, while SuperGrok costs $30/month and adds higher limits plus image and video generation. Free limits vary, and the API bills per token, so check xAI's live pricing before paying.
Why — the first-principles explanation
Free tiers in AI are not marketing generosity — they're a loss leader with a meter on it, and the meter exists because the economics are unforgiving. Every reply you get burns GPU time on hardware that costs billions and draws serious power. Unlike a search result, which can be cached and served a million times for nearly nothing, each Grok answer is computed fresh, for you. There is no version of this where unlimited free is sustainable — TechCrunch reported xAI burning roughly $1 billion a month around the time of the SpaceX merger.
So the free tier gets shaped by cost per unit of output, and you can see the exact shape in xAI's own API price list. Text is cheap: Grok 4.5 runs $2.00 per million input tokens and $6.00 per million output tokens under 200k context. A million tokens is roughly 750,000 words. That's why chat can be free — thousands of free conversations cost less than one engineer's afternoon. Images and video are not cheap. The same price list charges $0.02 per image, $0.05 for a quality image, and $0.080 per second of video on the 1.5 model. A 10-second clip is 80 cents of raw compute — 40x a still image, and that's before anyone's margin.
That single ratio explains everything about the tiers. Free chat: fine, it's rounding error. Free video: financially impossible at scale, since a few enthusiastic users could burn hundreds of dollars a day each. So xAI progressively walled it off and closed the last free image door on March 19, 2026.
The second thing the free tier does is route you by intensity. Light users hit a cap and shrug. Heavy users hit the cap and pay — which is the point. Reported consumer tiers as of 2026-07 span X Premium at $8, SuperGrok Lite at $10, SuperGrok at $30, X Premium+ at $40, and SuperGrok Heavy at $300 a month. Worth knowing: xAI does not publish a fixed free quota, and free limits change without notice — trackers in mid-2026 report roughly 10 prompts per two-hour window on a lighter model, but treat any specific number as a snapshot, not a promise.
An example that makes it click
A bakery gives away a free sample at the door. Costs them two cents, and the smell brings you in. That's free Grok chat.
Now imagine the samples were whole wedding cakes. Nobody hands those out, no matter how good the marketing. That's video generation — eight cents a second of pure compute, so a 10-second clip is 80 cents before anyone gets paid. Free chat is a sample. Free video was a wedding cake, and the bakery stopped on March 19, 2026.
How to do it
- Try free first: go to grok.com or install the Grok app on iOS or Android and sign in. No payment method required for basic chat.
- Find your ceiling: use it normally for a day. If you never hit the cap, you're done — free is genuinely enough for casual use.
- If you only want images and video, look at the cheapest Imagine-capable tier rather than jumping to full SuperGrok — SuperGrok Lite was introduced March 25, 2026 at a reported $10/month specifically for this gap.
- If you already pay for X, check what your subscription includes before buying anything else — X Premium and Premium+ bundle Grok access.
- If you're building software rather than chatting, skip subscriptions entirely and use the API: Grok 4.5 at $2.00/M input and $6.00/M output tokens is far cheaper than a seat for light programmatic use (as of 2026-07).
- Verify current prices at x.ai or grok.com before paying — tiers and free limits have changed repeatedly through 2026.
Key facts
- xAI's current pricing lists a Free plan at $0/month with web/X search and voice; the exact free quota is not fixed on the public page, so check the live account limits.
- The current comparison puts image and video generation, higher rate limits and frontier-model access in SuperGrok rather than the $0 Free plan.
- SuperGrok is listed at $30/month; other tiers and feature availability can vary, so verify the live comparison before subscribing.
- xAI API pricing as of 2026-07: grok-4.5 at $2.00/M input and $6.00/M output tokens under 200k context, rising to $4.00/$12.00 at or above 200k; grok-4.3 at $1.25–$2.50/M input.
- Imagine API pricing as of 2026-07: $0.02 per image, $0.05 per quality image, $0.080 per second for video 1.5, $0.050 per second for the older video model.
- Grok was launched November 4, 2023 as a paid-only feature for X Premium+ subscribers; free access came later.
- xAI was reported to be burning roughly $1 billion per month as of the February 2026 SpaceX acquisition.

▶ The 60-second explainer (script)
Is Grok free? Partly — and the split tells you something. Chatting is free. Go to grok dot com or the app, sign in, no card needed. You get a smaller model and a usage cap that resets every couple of hours. Images and video? Not free. xAI closed the last free image door on March 19, 2026. Here's why, and it's just arithmetic. Look at xAI's own API prices. Text: two dollars per million input tokens. A million tokens is about seven hundred fifty thousand words. So thousands of free conversations cost less than one engineer's afternoon — free chat is a rounding error. Now video: eight cents per second. A ten-second clip is eighty cents of raw compute, before anyone's margin. That's forty times a still image. A handful of enthusiastic users could burn hundreds of dollars a day each. Free video was never sustainable, and xAI was reportedly burning a billion dollars a month around the SpaceX merger. So the free tier isn't generosity — it's a sample with a meter. Light users shrug at the cap. Heavy users pay. As of July 2026, SuperGrok is thirty dollars a month, with cheaper tiers around eight and ten dollars and a three-hundred-dollar Heavy plan. One warning: xAI doesn't publish a fixed free quota, and these numbers have moved repeatedly this year. Check the site before you pay.
What authoritative sources say
People also ask
How many free messages do I get?
xAI doesn't publish a fixed number, and it changes. Trackers in mid-2026 report roughly 10 prompts per two-hour window on a lighter model. Treat any specific figure as a snapshot, not a guarantee.
Can I generate images or video for free?
No. xAI removed the last free Grok Imagine image access on March 19, 2026. Generation now requires a paid tier — the cheapest Imagine-capable option reported is SuperGrok Lite at $10/month.
Do I get Grok with X Premium?
Yes. X Premium and Premium+ both bundle Grok access — check what you already pay for before adding a separate SuperGrok subscription.
Is the free version the same model?
No. Free users get a lighter, faster model. The newest model — Grok 4.5, released July 8, 2026 — rolls out to paid tiers first, with the highest limits on SuperGrok Heavy.
Is the API cheaper than a subscription?
For light programmatic use, yes — $2 per million input tokens goes a long way. For heavy daily chat, a flat subscription is usually cheaper and simpler. The API has no free tier.
