Grok 4 Is Here: xAI’s Smartest Chatbot Yet
On July 10, 2025, Elon Musk’s AI company xAI officially launched Grok 4, the latest version of its chatbot—designed to be smarter, faster, and more helpful than ever.
Grok 4 builds on the earlier Grok 3 and comes with powerful new features and upgrades that target researchers, coders, and curious users alike.
What’s New in Grok 4?
Grok 4 is being hailed as a next-gen AI system. Here’s what makes it different:
Smarter Thinking: Uses first-principles, axiom-based logic, claiming PhD-level reasoning. It can even help discover new tech.
Massive Memory: Supports a 130,000-token context window (with up to 256,000 tokens via API), making it ideal for long conversations or complex documents.
Real Coding Power: Integrated with Cursor IDE, it supports live coding workflows with a built-in file editor.
Multimodal Coming Soon: Right now it’s text-only, but image understanding and generation are on the way.
High-Speed Infrastructure: Runs on the Colossus supercomputer, using thousands of GPUs for speed and scale.
DeepSearch: Searches the web in real time.
Voice Mode: Coming soon, with a British-sounding assistant named “Eve.”
Future Tools: Coding agent in August, multimodal agent in September, video AI in October.
