Elon Musk confirms xAI's Grok 4 launch for July 9: Where to watch, features

Elon Musk announces that its AI entity xAI will launch the Grok 4 on July 9 at 8PM PT via livestream. The new xAI model will bring enhanced reasoning, coding features, and dual-model capabilities

Elon Musk has confirmed that Grok 4, the latest AI language model from his artificial intelligence venture xAI, will launch on July 9. The announcement was made via a post on X (formerly Twitter), where Musk wrote: “Grok 4 release livestream on Wednesday at 8pm PT @xAI.”

 

The confirmation follows earlier comments from  Elon Musk, who had hinted in June that Grok 4 would arrive “just after 4 July.” Notably, this launch comes after xAI skipped the public release of Grok 3.5, pushing ahead with what is expected to be a significantly more capable version.

Grok 4 Launch: Date and time

• Date: July 9, 2025
• Time: 8:00 PM PT (8:30 AM IST on July 10)

xAI’s Grok 4: What to expect

According to a report by TestingCatalog, Grok 4 will likely arrive in two variants, each targeting a different segment of users, generalists and developers.

Grok 4 (Generalist model)

This version is designed to be a versatile AI assistant, positioned to compete directly with leading models in the general-purpose AI space. It is expected to feature:

• Calling functions
• Structured output generation
• Advanced reasoning and logic capabilities
• Strong performance across NLP, mathematics, and code comprehension
• Grok 4 aims to handle a wide variety of tasks, including writing, research, translation, and more.

Grok 4 Code (Developer-focused model)

This variant is tailored for software developers and will be integrated into tools like Cursor, a code editor. Grok 4 Code is expected to offer:

• Code generation and completion
• Bug detection and debugging assistance
• Contextual software development support
• It is positioned as a coding companion, designed to support professional and hobbyist developers in streamlining workflows and writing more efficient code.

With Grok 4, xAI is seeking to challenge established players in both consumer-facing and enterprise-level AI segments. The launch marks another key step in Musk’s effort to develop AI tools that align with his long-standing focus on reasoning transparency and open scientific inquiry.
