xAI’s Grok Build platform introduced the /deep-research command, which deploys multiple parallel agents to break down research questions, verify sources independently, and deliver a comprehensive report with citations and a list of what it could not find. The agents aggregate verified claims, cross-reference evidence, and independently validate information. The feature integrates with Exa for real-time web searches and page readings. Access is limited to SuperGrok and X Premium+ subscribers with no additional fees beyond standard subscription limits. User feedback has been notably positive, with early adopters highlighting time savings. Public discussions and announcements peaked around July 26, 2026.
