Grok

Elon Musk's AI chatbot, built by his company xAI.

Grok is the chatbot from xAI, the AI company founded by Elon Musk. It is wired into X (formerly Twitter), answers with a deliberately irreverent tone, and competes on price as much as on capability.

Grok matters in the news because xAI moves aggressively: rapid releases and steep price cuts that force the rest of the market to respond.
