Grok

Grok is xAI's large language model, accessible via X (formerly Twitter) Premium subscriptions and the Grok.com standalone interface, differentiated primarily by its real-time access to X's full post feed, giving it current information about events, trends, and public discourse that models limited to training data cutoffs cannot access. xAI now operates as SpaceX's AI division following a February 2026 acquisition, and Grok 4.6, released August 12, 2026, is the first model built jointly with the newly closed Cursor team, adding a 500,000-token context window and a new xhigh reasoning effort level that puts it on par with GPT-5.6 Sol on independent benchmarks. Grok Bot, a beta feature launched the same day, adds autonomous AI teammates that can sign into your other apps and run multi-step work in parallel for SuperGrok Heavy subscribers. Its Deepsearch mode conducts multi-step research sessions, querying the web and X's data simultaneously to build comprehensive answers to complex questions.

The Think mode applies extended reasoning to logic, math, and analytical problems, publishing its reasoning chain before the final answer, and a newer Voice Think Fast mode speeds up real-time spoken conversation with the model. The image generation feature (Aurora model) produces high-quality images from prompts and is particularly noted for fewer content restrictions than competing commercial platforms. Access is included with X Premium ($8/month) or available directly at Grok.com.

Grok's position is strongest for users who want real-time social media intelligence integrated into their AI queries, understanding what the public conversation currently is about any topic, and for users who want fewer generation guardrails on creative content.
