What is Grok AI?
Grok is the chat assistant from xAI, offered in its own app, on grok.com and inside X, with plans set by xAI and X. xAI's API documentation lists Grok 4.7 as its most capable chat model as of this check, alongside Grok Imagine models for image and video (xAI). UniqAI runs Grok 4.3 for chat; Grok Imagine is not in UniqAI, and images here come from Nano Banana or Flux.
Grok in UniqAI
| Model | Tier | Cost per message | Plan | Notes |
|---|---|---|---|---|
| Grok 4.3 | Smart | 5Gems | Any plan | Direct style; accepts images; 1,024-token answers on the free plan, 2,048 on paid |
Reached through xAI's API. xAI's own apps list newer versions (Grok 4.7 in the API docs); this page is updated when UniqAI's version changes.
How is this different from the Grok app?
The Grok app ties into X for live posts, has voice and Grok Imagine for pictures and clips; none of that is in UniqAI. What UniqAI adds is a cost per message rather than an X or SuperGrok plan, Grok 4.3 next to GPT-5, Claude Sonnet 4.6 and Gemini 2.5 Pro in one thread, and no X account. A new account starts with 30 Gems, six Grok 4.3 messages. For video or images, switch the composer to Kling 3.0, Veo 3, Nano Banana or Flux.

Questions about Grok AI App Explained, or Chat With Grok 4.3 per Message
Is Grok AI free?
Grok's own access, in the Grok app, on grok.com and inside X, is set by xAI and X and changes; check their current terms. In UniqAI each Grok 4.3 message costs 5 Gems on any plan, shown before you send, and a new account starts with 30 Gems.
Can Grok make images or videos here?
No. Image and video in xAI's lineup come from Grok Imagine, which is not in UniqAI. In UniqAI, images come from Nano Banana (12 Gems) or Flux Schnell (3 Gems), and video from Kling 3.0, Veo 3 or Wan 2.5, all in the same composer.
Which Grok version does UniqAI run?
Grok 4.3, through xAI's API. xAI's API docs list newer models, including Grok 4.7, as of this check (see Sources). The date at the top of the page is the last check, and this page is updated when the version in UniqAI changes.
Do I need an X or xAI account?
No. UniqAI reaches Grok through xAI's API under its own account; you sign in to UniqAI, pick Grok 4.3 and send. UniqAI is not affiliated with xAI or X, and the chat has no access to X posts.
What is Grok good for compared with GPT-5 or Claude?
A more direct, informal style, which some people prefer for feedback and debate-style prompts. GPT-5 and Claude Sonnet 4.6 cost the same 5 Gems, so ask the same question to two of them in one thread and keep the answer you like.
