Grok 4: Everything You Should Know About xAI’s New Model
Grok 4 is xAI’s most advanced large language model, representing a step change from Grok 3. With a 130K+ context window, built-in coding support, and multimodal capabilities, Grok 4 is designed for users who demand both reasoning and performance.
If you’re wondering what Grok 4 offers, how it differs from previous versions, and how you can start leveraging its features—this post covers everything you need to know.
What is Grok 4?
Grok 4 is the flagship model by xAI, announced on July 10, 2025. It introduces:
- First-principles reasoning: Improved logical consistency and deeper analytical capabilities.
- Comprehensive multimodal support: Initially supporting text, with vision and image-generation features expected soon.
- Specialised coding edition (Grok 4 Code): Enhanced integration into developer workflows with real-time IDE capabilities.
- Release Timeline: It is released on July 10, 2025.
- Milestone: First xAI model to integrate flagship language, vision, and coding functionalities under one unified API.
Partial API access is already available, and the developer community is actively exploring Grok 4’s new endpoints.
