Grok is xAI’s assistant, deeply integrated with X (Twitter) for real-time information and known for a candid, less-filtered tone. In 2026 it grew into a full product suite: Grok Chat, Voice, Imagine (image generation), video generation and Grok Build for coding, all bundled with X Premium features on paid tiers.
The October 2026 X Subscription replaced SuperGrok and X Premium+ with five tiers: Free, Plus $8, Premium $30 (xAI’s recommended tier), Super $100 and Ultra $200. Every plan draws from one weekly usage pool shared across Chat, Imagine, Voice, Build and Cursor. Grok 4.7 is the current flagship model with a 500K-token context window on the API.
