Grok Build built Cubs app

Jon Shulkin said on May 23 that he and his son used xAI’s Grok Build to create a Chicago Cubs fan app during “2 innings of the game” and deployed it to Google Cloud. His post on X said the app included a live API feed, scores, standings, news, user accounts and posting features. (digg.com) Digg republished the post on May 24, amplifying it beyond X. xAI’s Grok Build page describes the product as a beta tool for planning, building, testing and deploying software. (x.ai) ### What exactly did Jon Shulkin say he built? Jon Shulkin wrote at 8:11 p.m. on May 23 that “Grok Build is pretty amazing” and said he and his son built a Cubs app with “a live API feed, scores, standings, news, users, and ability for users to post.” The post said the work was completed during two innings of a Cubs game and deployed to Google Cloud. The features listed in the post describe a small but complete fan product rather than a single-page mockup. (digg.com) Scores and standings are standard live sports data elements, while user posting implies the app also included at least basic account or content functionality, according to Shulkin’s description. ### What is Grok Build, according to xAI? xAI’s product page says Grok Build is in beta and pitches it as “One tool for the entire development workflow.” The page says the tool can “plan, build, test, and deploy,” and that it delegates larger tasks to specialized subagents that can run in parallel. (digg.com) The same page presents Grok Build as a terminal-based development tool that works with existing codebases and languages. xAI says users can install it with a single shell command and run it in their terminal.

A working cloud deployment gives the example a different shape from a screenshot-only prototype or a local demo. (x.ai) Google Cloud already has ties to baseball data infrastructure. Google Cloud says Major League Baseball uses its systems for real-time fan and game-data services, and MLB has described delivering real-time data to fans and broadcasters through Google Cloud-backed infrastructure. (x.ai) That does not show Shulkin used MLB’s official systems, but it places the cloud choice inside an existing baseball-data ecosystem. ### How much of this is verified beyond the social post? (digg.com) Digg’s May 24 item reproduced Shulkin’s X post and the core claims about timing, features and deployment. The underlying demonstration remains a social-media claim, and no public code repository or product page for the Cubs app appeared in the material reviewed. xAI’s own documentation verifies that Grok Build exists and is being marketed as a coding and deployment tool. The available sources do not independently document the app’s source code, cloud architecture or exact live data provider. (cloud.google.com) ### Where would a reader look next? xAI’s Grok Build beta page is the primary source for the product’s current capabilities and installation details. Jon Shulkin’s May 23 X post remains the primary public source for the Cubs app claim, and any next step would likely be a shared repo, demo link or follow-up post from Shulkin or xAI.
