xAI is developing deployable applications for Grok Build, allowing users to deploy, host, and publicly share apps built with Grok, with support for custom domains, mirroring Google AI Studio’s build-and-publish flow; neither capability is available yet, and no timeline has surfaced. Since June, paid Grok plans draw from a single weekly usage pool shared across Chat, Imagine, Voice, and Build, with extra credit top-ups sold on the web, and this top-up flow is set to reach the Grok mobile app. Elon Musk said on July 18 that xAI's 2 trillion parameter base model, reportedly named Grok 4.6, will finish initial training next week, claiming it beats the 1.5 trillion parameter foundation behind Grok 4.5 in every way and might exceed Moonshot's Kimi K3 while keeping speed and token efficiency close to Grok 4.5, with customer availability targeted for August.
