Hey there, fellow Grok explorers! Whether it was cracking math puzzles, spinning tales, or hallucinating brick-throwing basketball stars, Grok’s been a ride. But with all its fancy terms—AIME, DeepSearch, Big Brain Mode—it’s easy to get lost in the jargon. That’s where this glossary comes in.
Think of it as your trusty map to Grok’s universe. For the tech wizards, we’ve got the nitty-gritty: scores, features, and what makes Grok tick, straight from xAI’s playbook. Not a techie? No sweat—we’ve added simple, everyday explanations too, like calling Colossus a “mega-smart factory” instead of a GPU beast. Whether you’re here to geek out or just curious about this quirky AI, we’ve got you covered.
