Such a feature enables it to correct its own errors and provide accurate answers. The extended contextual window of this model, reaching over 130,000 tokens in the application and up to 256,000 tokens via its programming interface (API). This gives it an in-depth understanding of vast quantities of data, including entire code bases. ➥ How does Grok 4 operate? Its operation integrates several components for the smoothest possible experience. The model is accessible via the X application, the xAI API, and the grok.com website. It has been specially designed to provide intelligent, real-time information thanks to its DeepSearch functionality, which draws directly on up-to-date data from the X social network and the web. Multi-modal skills and remarkable responsiveness Grok 4 supports text input, visual input and image generation, with augmented abilities for image interpretation. Also, its refined voice capabilities ensure natural, soothing interactions. In continuation, a “Heavy” version implements a multi-agent system, where multiple AI agents collaborate to solve hard problems and polish results. A trusted code assistant For development professionals, Grok 4 Code is a valuable aid. This variation facilitates code generation, completion and debugging, with direct integration into integrated development environments (IDEs). You can even submit complete source code files for correction. (Now that’s impressive!) A distinct personality Grok 4 is known for its conversational tone, often infused with humor, which makes the dialogue more engaging. What’s more, it’s also renowned for its ability to provide direct answers, not hesitating to broach subjects that other conversational agents might avoid. However, this approach has generated some controversy in the past, which xAI strives to manage through moderation adjustments.

Early reactions to Grok 4 have been glowing, with some even calling it AGI (General Artificial Intelligence). This LLM model is considered a powerful tool, prepared to solve questions at a high level and debugging full code bases. It is also superior to existing tools such as Cursor. Reviews also show that it outperforms its direct rivals, such as Claude 4 , Google Gemini 2.5 Pro or OpenAI o3, on several test benches. Review of the AIxploria team At the time of writing, this new model is the best LLM on the market. However, it’s worth mentioning that previous versions of Grok have sparked debate over the unfiltered nature of some of their responses. xAI has taken this feedback on board and is actively working to improve the model’s ability to filter out inappropriate content while retaining its “truth-seeking” aspect.
