Grok

Grok combines a conventional chat model (currently Grok 4.5) with a research function called DeepSearch, which searches the web and X in multiple steps and cites its sources. It also includes image and video generation called Grok Imagine, a voice mode with several voice personas, and agents for task-based execution of research and analysis work. Its core advantage is real-time access to X content, for example for trend or news research, an area where assistants without a live connection reach their limits.

According to the source, moderation is noticeably looser than with comparable assistants. This can be an advantage for creative applications, but it also means outputs should be reviewed before brand-safe use. The source also notes a political bias: xAI's positioning differs from other providers, which needs to be factored in for brand-safe and compliance-sensitive use. No dedicated system prompt exists for this tool; it is a finished product without a configuration layer within the scope documented here.

German works, but according to the source the optimization focuses primarily on English-language use. For enterprise compliance contexts, Grok reportedly offers fewer features than established providers such as OpenAI or Anthropic.

According to the source, Grok is available through grok.com and the X app, with a free tier for initial testing. Access is now tiered: a free plan with the smaller Grok 4 Mini model, X Premium (around 8 US dollars per month) and SuperGrok Lite (around 10 US dollars) with limited functionality, SuperGrok (around 30 US dollars) and X Premium+ (around 40 US dollars) with the main model, and SuperGrok Heavy (around 300 US dollars) for immediate full access to the current top model, Grok 4.5.

A note on data protection, according to the source: chats can be used for training by default, and an opt out is available in the settings. This should be reviewed before production use, particularly with company data.
