Grok in one minute
Grok can answer questions, find information, produce text or code and work with tools. For current topics, it can consult public X posts and web sources. This can make an answer easier to check, but not automatically true or complete. Available models and features differ between X, the standalone apps and the API.
Grok as an assistant and search interface
The Grok assistant combines an LLM with the features offered by a product. The model processes context; search tools retrieve information. Current knowledge therefore does not come solely from training. X’s help documentation explains that Grok can choose to search public posts and the web.
Example: a brand wants to understand questions following a product launch. Ask Grok to collect public posts from a defined period, separate themes and link to the originals. Treat the result as initial research material, not a representative survey.
A popular post can be wrong. A summary can miss irony. Check the original source, date and context before using conclusions in a campaign. Grok does not have unlimited access to private messages or every page on the internet.
Voice, coding, media and agents
Grok is also used for spoken interaction and programming. The developer offering includes separate speech services. Images and video remain part of the range: current release notes list Grok Imagine Image 2.0 and Grok Imagine Video 1.5. These media models are distinct from the general text model.
Through the API, developers can use web search, X search and other tools in an application. A model that proposes a search still needs an environment to execute it. That environment determines access, processing and permitted actions.
Grok Bot is an agent product with its own computer environment and routines. It can work with connected apps and return when approval is needed. Grok Build focuses on software development. These products illustrate why AI Agents add another layer around a model.
An illustrative agency workflow: collect relevant sources, draft an analysis and prepare a report. Record which steps actually happened and which remain proposals. A chat response about a planned task is not proof that the action was completed.
Current Grok models and access
On 7 October 2026, Grok 4.7, released on 21 September, is the latest general model in the official documentation. It is available through channels including the API and Grok Build, with a focus on coding, knowledge work and extended tasks with tools.
Grok 4.7 Fast is a faster serving variant of the same model in Cursor and Grok Build; the release notes say it is not available through the public API. This does not establish that every X account automatically uses Grok 4.7.
For marketing, access to public conversations on X is a distinctive integration. Compare that access and the required tools against your research question. One benchmark cannot determine which assistant is most suitable for source research, editing or automation.
