🚨GROK X HEAVY HITS XXXX% ON HUMANITY'S LAST EXAM WITH TOOLS

The difference between Grok X and Grok X Heavy? 

Pure thinking power. 

Heavy takes 32x more time to crack problems and nearly doubles the score.

Give it tools and time to think, and Grok Heavy solves half of the hardest test ever created. 

That's PhD-level performance across every academic field.

The $300/month tier suddenly makes sense. 

You're paying for an AI that actually stops and thinks.
