Grok 3.5 to Feature Automatic DeepSearch and Think Modes

In a groundbreaking announcement today, Elon Musk, the visionary CEO of xAI, took to X to reveal a significant upgrade for the company's artificial intelligence platform, Grok. At 2:31 PM UTC (10:31 AM EDT) on Monday, June 16, 2025, Musk posted that Grok 3.5 will automatically activate its highly anticipated DeepSearch and Think features as needed, marking a leap forward in AI accessibility and functionality. Although Grok 3.5 has not yet been released, the news has already sparked excitement and speculation across the tech community.

The tweet, which quotes an earlier post by user @IterIntellectus about using DeepSearch to aggregate and analyze news, signals xAI's intent to streamline the user experience. DeepSearch, a mode that iteratively scours the web for information, and Think, designed for complex problem-solving, will no longer require manual toggling. This automation is expected to make Grok 3.5 more intuitive, allowing users to harness its full potential without needing advanced technical know-how.

"DeepSearch and Think will activate automatically as needed in Grok 3.5," Musk wrote, emphasizing the importance of the update. The post has since garnered significant attention, with over 500 retweets and 2,000 likes within the first hour, alongside a flurry of responses from tech enthusiasts and AI developers.
