Grok

FreemiumAI chatconversational ai

Grok is xAI's assistant, tightly integrated into X (Twitter) and known for real-time access to public posts and a less-filtered, more conversational style. The latest Grok 4 and Grok 4 Heavy models are strong at reasoning, and the product includes image generation and voice. Access is bundled with X subscriptions or sold as standalone SuperGrok plans, with a developer API for the Grok model family. Its edge is live X data and personality; its limits are the convoluted subscription tie-in and a smaller ecosystem than the frontier labs.

Freemium · or standalone SuperGrok ($30/mo) and SuperGrok Heavy ($300/mo). Developer API billed per-token for the Grok 4.x family. As of June 2026.
