Grok is xAI's AI chatbot and model family, offering advanced reasoning, real-time web search, image and video generation, and voice interaction capabilities. Built by Elon Musk's xAI, Grok distinguishes itself with deep integration into the X (formerly Twitter) platform and a distinctive personality that embraces direct, unfiltered responses. Grok addresses the demand for an AI assistant with real-time information access and strong reasoning capabilities, available through grok.com, the X platform, and dedicated mobile apps.
Grok offers multiple model and product surfaces, including Grok 4.3 for reasoning and tool-use workloads and Grok Build 0.1 / grok-code-fast for agentic coding. Current xAI API docs list Grok 4.3 with a 1 million-token context window and Grok Build 0.1 with a 256,000-token context. Grok Studio, live search, DeepSearch-style research, image/video capabilities, and coding-tool integrations should be treated as plan- and product-surface-specific features that need live verification before purchase decisions.
Grok serves users who want an AI assistant with real-time information access and strong reasoning capabilities, from casual X users to developers building with the xAI API. Current API pricing is model-specific: Grok 4.3 is listed at $1.25 per 1M input tokens and $2.50 per 1M output tokens, while Grok Build 0.1 is listed at $1.00 per 1M input tokens, cached input at $0.20 per 1M, and $2.00 per 1M output tokens. It competes with ChatGPT, Claude, and Gemini by emphasizing X integration, live search, and increasingly specialized coding models.
