xAI's real-time assistant with Grok Imagine image & video generation
Overview
Grok is xAI's truth-seeking AI assistant, built around live access to the web and X (formerly Twitter) with citations from primary sources. It answers with step-by-step reasoning, generates images and short videos with Grok Imagine (up to 2K resolution and 15-second clips), holds natural low-latency voice conversations, and analyzes files, PDFs and screenshots. A free tier is available on web, iOS and Android, while SuperGrok ($30/month) unlocks higher limits and a multi-agent reasoning mode where parallel agents tackle sub-problems and merge their work into one cited answer. Developers can reach the same models — text, vision, image and video — through the xAI API.
