Grok
xAI's assistant, built around live access to X and a noticeably looser attitude than most of its rivals.
What is Grok?
Grok is xAI's assistant, and it wears its origin on its sleeve: built by Elon Musk's AI lab, launched inside X in late 2023, and still most useful when a question involves something happening right now. Where ChatGPT or Claude are trained on data with a cutoff and only reach further with a web search tool bolted on, Grok has always had live access to the X firehose baked into the product — so it tends to be sharper on breaking news, trending arguments, and "what is everyone saying about this" questions than its competitors.
xAI has also leaned hard into media generation. Grok Imagine, its image and video tool, produces short clips fast and has grown into one of the highest-volume generation tools in the industry by sheer usage. The trade-off, and it's a real one, is that Grok's content policies are noticeably more permissive than ChatGPT's, Claude's or Gemini's, which is part of the appeal for some users and a dealbreaker for others. Ownership changed hands too: SpaceX acquired xAI in February 2026, folding Grok into Musk's wider company family.
Grok Imagine usage figure comes from SpaceX's own S-1 filing (Q1 2026). Context window applies to the current flagship API model; the consumer app's context window is smaller and varies by plan. Figures may change — check xAI's site for current details.
Key features
Real-time X access
Reads live public posts, so it can speak to what's trending right now instead of guessing from old training data.
Grok Imagine
Fast image and short-video generation, with an "Extend from Frame" tool for chaining clips together.
DeepSearch
Runs a live, cited web search rather than answering purely from what the model already knows.
Think / Big Brain mode
An extended-reasoning setting for harder questions, similar in spirit to "thinking" modes elsewhere.
Grok Voice
Spoken conversation mode, rolled out publicly in June 2026 for the mobile app.
Grok 4 Heavy
A multi-agent mode where several model instances work a problem in parallel and cross-check each other.

Our verdict
Grok is at its best when a question is genuinely about right now — breaking news, a trending debate, something moving fast enough that a static model would just hedge. That's a real and fairly narrow strength, and xAI has built a legitimately fast-moving product around it, especially on the media-generation side with Grok Imagine. It's a harder recommendation as an everyday, do-everything assistant: the pricing sits above ChatGPT and Claude at the equivalent tier, model versioning is opaque enough that you can't always tell what you're talking to, and the looser content policy is a feature for some users and a reason to look elsewhere for others. Worth having if X and real-time relevance matter to you; not the obvious first pick otherwise.
FAQ
Do I need X Premium to use Grok?
No. Grok is available as a standalone product at grok.com and through its own apps, separate from X Premium+, which bundles Grok with X platform perks for users who want both.
Who owns Grok now?
Grok is built by xAI, which was acquired by SpaceX in February 2026. Both remain part of Elon Musk's group of companies.
What is Grok Imagine?
xAI's image and video generation tool, capable of producing short clips quickly and, according to SpaceX's own disclosures, generating over a billion videos a month as of early 2026.
Is Grok's content less moderated than ChatGPT or Claude?
Generally, yes — xAI has taken a more permissive approach to what Grok will generate compared to most competitors, which is a deliberate product choice rather than an oversight.
What does SuperGrok Heavy add over standard SuperGrok?
Access to Grok 4 Heavy, a multi-agent mode where several model instances work in parallel on the same problem, plus substantially higher usage limits.
Is Grok 5 out yet?
Not as of July 2026. Earlier Q1 and Q2 2026 target windows both slipped; xAI continues to ship incremental updates (Grok 4.3, Grok Voice, Grok Imagine upgrades) while a full Grok 5 release remains unconfirmed.
