Grok is a conversational AI assistant developed by xAI, the artificial intelligence company founded by Elon Musk in 2023. It runs on the Grok family of large language models, with Grok 3 (released February 2025) as the current flagship. Unlike most AI assistants, Grok is natively integrated with the X (formerly Twitter) platform, giving it real-time access to posts, trending topics, and public discourse. It is trained on xAI's Colossus supercomputer, which houses approximately 200,000 NVIDIA H100 GPUs.
Grok offers a freemium model. Free-tier users get limited daily queries using the Grok 3 mini model. The SuperGrok subscription costs around $30/month and unlocks full Grok 3 access, higher usage limits, DeepSearch, Think mode, and image generation. Premium+ X subscribers ($40/month) also get full Grok access bundled with X platform benefits. There is also a Grok API available for developers with usage-based pricing through the xAI API platform.
Grok 3 is competitive with GPT-4o, Claude Sonnet 4, and Gemini 2.0 on major benchmarks — scoring 93.3% on MATH-500 and 85.7% on GPQA Diamond. Its key differentiator is real-time X integration, which no competitor offers natively. Grok's content policies are noticeably less restrictive, allowing topics and image generation that other models refuse. However, ChatGPT has a far larger plugin ecosystem, Claude offers longer context windows, and Gemini has deeper Google Workspace integration.
DeepSearch is Grok's multi-step research feature that synthesizes information from across the open web and X platform into comprehensive, cited answers. Instead of returning a single search result, it iteratively explores sources, evaluates them, and assembles a synthesized response with inline citations. This makes it useful for market research, due diligence, breaking-news analysis, and academic research where source transparency matters. It competes directly with Perplexity AI and ChatGPT's deep research mode.
Yes. Grok generates images using the Aurora model, which produces photorealistic outputs from text prompts and notably permits content (including images of public figures and edgier styles) that ChatGPT, Gemini, and Midjourney typically restrict. Video generation is supported through integration with the Flux video model. Both capabilities are available to SuperGrok subscribers, while free users have more limited image generation access. Outputs are intended for creative, satirical, and exploratory use rather than commercial production at scale.
