Grok

Developed by xAI, Grok has transformed from an X-exclusive chatbot into a standalone frontier AI ecosystem accessible at grok.com, on iOS and Android, inside the X platform, and via the xAI API. By late 2026, xAI retired the original Grok 3 and initial Grok 4 checkpoints in favor of an upgraded Grok 4 family led by Grok 4.7 (released September 21, 2026, 500K-token context window), alongside Grok 4.5, the 1M-context Grok 4.3, the 2M-context Grok 4.1 Fast, and the specialized Grok Build 0.1 coding model.

Grok differentiates itself through unfiltered real-time information retrieval and an integrated creative and coding suite. Its DeepSearch engine synthesizes live breaking news, public sentiment, and primary discussions directly from the X firehose alongside the open web—giving it a distinct real-time edge over static-cutoff competitors. Within the grok.com workspace, paid users share a unified weekly compute pool across conversational reasoning, Voice mode, Imagine (native photorealistic image and video generation), Grok Bot automation, and Grok Build (which replaced the older Grok Studio as xAI's dedicated agentic coding environment).

In October 2026, xAI streamlined its consumer pricing by unifying standalone SuperGrok plans and X Premium memberships into The X Subscription—bundling full Grok access, X Premium perks, and the Cursor code editor across five tiers: Free ($0), Plus ($8/month), Premium ($30/month, matching the classic $30/month SuperGrok tier), Super ($100/month, matching SuperGrok Plus), and Ultra ($200/month), while legacy SuperGrok Lite ($10/mo) and Heavy ($300/mo) subscribers remain grandfathered and Grok Business serves teams at $30/seat/month. On the xAI API, flagship Grok 4.7 is aggressively priced at $2.00 per million input tokens ($0.50 cached) and $6.00 per million output tokens for prompts under 200K tokens.
