Grok AI: What It Is, Features & Pricing (2026)

👁 139 reads

Grok is a chat interface and family of AI models from xAI, Elon Musk’s company. It does what ChatGPT or Gemini do - answers questions, writes text and code, generates images - but with two distinguishing features: it sees what’s happening on X in real time, and it responds in a looser tone, refusing less often. Below, we cover what it can do, what versions exist, how much the API costs, and when you should actually reach for it instead of the competition.

How Grok Differs from the Rest

Live access to X. This is the only major model with direct insight into current posts on X. When you ask questions like “what are people saying right now about this launch” or track a developing situation, it gives answers the competition can’t build from a search index. This is a real advantage, not a marketing gimmick.

Looser tone and fewer refusals. Grok was designed to sound less corporate and refuse controversial questions less often. For some, that’s a plus; for others, a risk, because the model more readily enters topics where errors are easier. With facts and numbers, verify just as you would with any other model.

Large context windows in cheaper versions. Older Grok variants accept one to two million tokens at rates below half what competing flagships charge. When processing large document sets, that’s an argument in itself.

Grok Versions and API Pricing

An interesting detail visible only in the table: the largest context window, two million tokens, belongs not to the newest model but to the March release Grok 4.20, and at the cheapest rate. If your problem is volume of material rather than finesse of response, an older version can be a better choice than the flagship. You can calculate the cost of a specific task in the API cost calculator, and find a comparison with all models in the AI model ranking and the model atlas.

Grok Subscription Pricing

We should be honest: xAI changed the rules several times in 2026, and plan names can be confusing. The paid product is called SuperGrok and you buy it at grok.com, while X Premium and X Premium Plus are subscriptions to the X platform itself that add Grok to social features. There’s no such thing as “Grok Premium.”

A free plan exists but gives a limited query pool and access to an older model, without features like deep search. Because pricing thresholds changed multiple times this year and the official price list isn’t publicly available for automated reading, check the current amount directly at grok.com before purchasing. If you’re comparing costs between tools, you’ll find a full subscription comparison in the article about AI subscriptions.

One note about privacy, because it’s often overlooked: conversations on the free plan may be used to train models. If you’re pasting company materials, check your account’s privacy settings or use a business plan.

How Grok Performs in Practice

We tested it alongside competitors on the same tasks. For short questions and commentary on current events, it’s fast and accurate. In longer texts in non-English languages, it falls behind Anthropic and OpenAI models: it more often reaches for calques from English and loses sentence rhythm. We ran our writing tests in Polish, a heavily inflected language, so this is a useful proxy for non-English writing quality. In code it does decently, but the dedicated Build 0.1 variant performs better than the general model. Comparison details are in the article Grok 4.6 versus GPT-5.6 Sol and Fable 5, where we compared four rounds of tasks and the bill for each.

When to Choose Grok and When Something Else

Reach for Grok when you’re working on the X platform, need commentary on what’s happening right now, or are building something on the API and looking for a large context window at a low price. Choose something else when writing long texts in non-English languages, analyzing company documents, or needing a predictable, cautious tone.

We’ve described alternatives separately: Gemini for people in the Google ecosystem, ChatGPT as a universal choice, Claude for texts and documents. We collect current news about subsequent Grok versions on the model card in the atlas.

Where You Actually Use Grok

There are three entry points, and this is one of the first things that confuses beginners. In the X service, as an assistant with posts, with access to what’s happening in the service at that moment. On a separate site and in the app, as a regular chat without X context. Through the API, if you’re building your own tool on it. The range of functions and limits differ between these entry points, so comparisons of “Grok versus ChatGPT” without specifying which entry point mean little.

What Grok Has That Competitors Don’t

One thing really can’t be faked: access to current posts from X. When you ask “what’s happening with this company right now,” Grok responds with material other models simply don’t see. This is a real advantage when tracking events live and checking sentiment around a topic. The second thing is Grok Imagine, an image and short video generator with the loosest moderation on the market; we write more about it in the context of xAI the company and in the video generator comparison.

What Not to Do with Grok

• Don’t treat X posts as sources. The model quotes what people wrote, not what happened; without verification, it’s gossip with nice formatting.
• Don’t generate images of real people. Loose moderation doesn’t mean it’s allowed; xAI has a series of lawsuits over this, and responsibility also falls on the user.
• Don’t paste company data on a personal account. The rules here are the same as in other chats; we describe them in the article is ChatGPT safe.

Grok and the Rest of the Market

For writing and working on documents, Anthropic and OpenAI models are stronger. For tasks with search and sources, it’s closer to Perplexity. For images without restrictions, it has no competition today, which is both an advantage and a risk. We show current model positions in the ranking, and prices of all subscriptions in the pricing hub.

Grok 4 and Newer Versions: What Changed

Grok’s numbering changes faster than competitors’, and it’s easy to get lost. Grok 4 was the version that first put xAI at the top of reasoning comparisons, and its name still appears most often in search. Subsequent releases went toward speed and lower cost per million tokens, not toward a big quality leap. Practical takeaway: if you have a choice of model in the app, for tasks requiring reasoning choose the newest available reasoning variant, and for short questions the fast one, because you won’t see a quality difference but you’ll get an answer several times faster. We show current positions of all models in the ranking, and cards with token prices in the model atlas.

Grok for Free

For free, Grok works on a regular X account with a daily message limit and in the xAI app after logging in. The limit renews every few hours and is perfectly sufficient for a few questions a day; broader access and more powerful model variants require a paid plan. For non-English writing, Grok understands everything and responds correctly, but in longer texts the output comes out weaker than competitors’: English calques and stiff syntax occur. For writing in non-English languages, we’d choose Claude or ChatGPT; for checking what the internet is talking about right now, Grok. We describe the image and video generator separately in the article Grok Imagine.
