Grok 4 is the latest AI model from xAI, a company founded by Elon Musk. It was launched in July 2025 and is designed to compete with top models like OpenAI’s GPT-4o and Google’s Gemini 2.5 Pro. Grok 4 skips version 3.5 and brings some powerful new features for both regular users and developers.
What Is Grok 4?
Grok 4 is a Large Language Model (LLM). It is built to give smarter, more logical answers. It also supports coding tasks, live data from X (formerly Twitter), and can perform step-by-step duties using a special system called agentic architecture.
Two Versions of Grok 4
Grok 4 comes in two versions depending on your needs:
Featured
Grok 4 (General)
- Best for writing, translating, researching, and everyday questions
Grok 4 Code
- Made for developers
- Helps with writing code, fixing bugs, and planning software using tools like Cursor
