Elon Musk’s AI venture, xAI, is all set to unveil the latest version of its language model — Grok 4 — on July 9, 2025. The release is scheduled for 8:00 p.m. Pacific Time, which is 8:30 a.m. IST on July 10 for Indian users. Musk confirmed the date and time in a post on X (formerly Twitter), stating:
“Grok 4 release livestream on Wednesday at 8pm PT @xAI”.
This announcement follows an earlier update in June, where Musk had hinted that Grok 4 would launch "just after July 4."
Initially, Musk had promised the launch of Grok 3.5 for SuperGrok subscribers back in May 2025. However, it now seems that xAI is skipping version 3.5 altogether and moving directly to Grok 4, possibly in response to the intensifying competition in the AI space from rivals like OpenAI, Google DeepMind, and Anthropic.
This sudden leap underscores xAI’s desire to accelerate product development and stay ahead in the rapidly evolving large language model (LLM) race.
Grok 4 is being positioned as a major upgrade over its predecessors and is expected to bring significant improvements across multiple fronts — particularly in reasoning, coding, and multimodal capabilities.
According to insiders, Grok 4 will focus on first-principles reasoning, making it more adept at solving complex mathematical and scientific problems. This puts it in the league of AI tools designed for research, education, and advanced problem-solving.
Musk has long emphasized that reasoning is the most important capability for AI to develop. Grok 4’s focus on logical thinking may give it an edge over competing models.
Earlier versions like Grok 3 already performed well:
93.3% on AIME 2025 (American Invitational Math Exam)
84.6% on GPQA (Graduate-level Physics Questions Assessment)
With Grok 4, xAI aims to exceed these benchmarks, potentially surpassing models from OpenAI’s GPT-4, Anthropic’s Claude, and others in the same category.
While Grok 4 is expected to support text-based interactions at launch, xAI plans to expand its multimodal capabilities over time. These include:
Image understanding and generation
Visual reasoning
Voice interaction
Embedded tools for coding and design
Multimodal functionality is becoming a critical differentiator in next-gen AI, and Grok 4’s roadmap seems to align with this trend.
According to multiple early users and testers on X, the xAI Console — the developer interface for Grok — has already begun posting updates related to Grok 4 access. A few highlighted messages include:
“Our latest and greatest flagship model, offering unparalleled performance in natural language, math, and reasoning — the perfect jack of all trades.”
Another message reads:
“A model purpose-built to be your coding companion. Ask it questions about your code or embed directly into your code editor.”
These statements suggest Grok 4 will not only serve general users but also cater to developers and engineers through API access and IDE integration.
The AI model space is heating up, and Grok 4’s release will be closely watched. While xAI is still in its early stages compared to tech giants like OpenAI and Google, Musk’s reputation and the rapid development cycles of Grok models are keeping it in the spotlight.
With models like GPT-4.5 already rolled out and OpenAI’s GPT-5 expected later this year, Grok 4 will need to offer distinctive capabilities to retain relevance and attract adoption.
With powerful reasoning features, coding support, and eventual multimodal upgrades, Grok 4 is being positioned as xAI’s most ambitious release to date. Whether it can truly compete with more established models will depend on performance, reliability, and real-world applications — all of which should become clearer post-launch.
For now, all eyes are on the Grok 4 livestream scheduled for July 9, 2025, at 8 p.m. PT.
