Forget Grok 3.5 - Grok 4 On The Horizon

Elon Musk took to X to share an exciting update about the latest developments at xAI, revealing that he and the team have been working tirelessly overnight on the next iteration of their AI model, Grok. In his tweet, Musk announced that the new model, dubbed Grok 4, is set to be released just after July 4th, following one final significant training run focused on creating a specialized coding model. This news has sparked widespread anticipation among tech enthusiasts and the AI community, especially given Musk's reputation for pushing boundaries with innovative projects like Tesla and SpaceX. The mention of good progress suggests that xAI is making substantial strides, potentially positioning Grok 4 as a game-changer in the AI landscape.

It’s worth noting that Elon Musk’s recent tweet on June 27, 2025, announcing the development of Grok 4, highlights an interesting leap in the naming convention of xAI’s AI models. The tweet mentions that the next release will be called Grok 4, skipping over what might have been expected as Grok 3.5. This decision to bypass a 3.5 version aligns with trends observed in the broader tech community, where companies sometimes opt to jump to a higher version number to signal significant advancements or a major overhaul.
