How to start
Pick Grok from the model selector. Not sure which model to use? Brainiac is one of the options in the picker and auto-selects for you. You'll always see which model answered, so you can compare it against another in a couple of clicks.
What Grok is good at
- Direct, conversational answers with a bit of personality.
- Technical and coding questions where you want a clear explanation.
- Thinking through a problem when you'd rather talk it out than get a one-line reply.
- Current-information questions — turn on web search so the answer can draw on what's happening now.
Tips for better results
- Be specific about tone. Tell Grok if you want a short answer, a detailed walkthrough, or a casual take.
- Turn on web search for anything time-sensitive.
- Attach what you're working from — a screenshot, a doc, a snippet of code.
- Compare. If Grok's answer isn't quite right, try the same prompt on another model. They're all in one place for exactly this.
Do I need X Premium or an xAI account?
No. Grok 4.3 is free and unlimited on Tusk Central AI, supported by privacy-respecting ads. No separate subscription required.
Is this the same as Grok on X?
Tusk Central AI is an independent platform that gives you access to Grok alongside models from other providers. It isn't affiliated with xAI.
