Grok 4 by xAI pairs fast, dependable reasoning with practical tooling for confidence and clarity.

It features a version such as “Grok 4 Code” tailored for software engineering tasks (code generation, debugging, and large-scale refactoring) designed to directly compete with other industry models.

Grok 4 supports extremely large context windows (reports cite up to 256,000 tokens) and is optimized for heavy workloads such as entire code bases, long documents or multi-step reasoning chains.
Grok 4 Heavy introduces a structure where multiple AI agents collaborate in parallel, rather than a single monolithic model handling everything. This allows it to compare perspectives, reduce hallucinations and produce more rigorous responses.
Tap into Grok 4’s deep-reasoning and long-context strengths to make sense of large-scale information, multifaceted problems and layered conversations. It empowers you to go beyond surface understanding into genuinely coherent perspectives.

Grok 4 pairs reliable reasoning with practical controls that fit teams of any size.
Grok 4 supports extremely large inputs and multi-turn conversations that stretch across hours or huge documents, so it won’t lose track of previous context or major shifts in topic.
It can pull in up-to-date information from the web, including social-media feeds and other live streams, so the answers reflect what’s happening right now rather than only historical data.
Beyond just text, Grok 4 can accept images (and is designed to expand into voice and video), allowing you to combine visual and textual inputs for richer, more flexible interactions.
For users working with software, Grok 4 provides enhanced assistance for code generation, debugging and large code-base understanding, making it more than just a “chat” tool.
In its advanced variant, multiple internal agents work together. Each tries different lines of reasoning, they compare results and pick the best one, so you get a more refined, robust answer.
The model supports returning data in structured formats (for example JSON or organized blocks) which makes it easier to integrate into workflows, apps or data-pipelines.
There’s a variant optimised for everyday use and a version tailored for more technical tasks, so it adapts to different user levels.
Because it’s deeply integrated with the X platform (formerly Twitter) and other real-time streams, Grok 4 can pick up on live trends, online discussions and rapid shifts in tone or topic.
Grok 4 has been trained and architected to handle multi-step reasoning, complex logic tasks and advanced academic style problems.
