Grok Build is a terminal coding agent that xAI announced on 25 May 2026, available in early beta to SuperGrok and X Premium Plus subscribers and, according to the product page, now running on the Grok 4.6 model. If you already live in a terminal, keep a repository with an AGENTS.md in it, and want plan-then-approve behaviour rather than inline autocomplete, it fits. If you are not paying for one of those two subscriptions, or you want something to produce a finished project rather than edit an existing one, it does not. The caveat worth naming is the beta label, which means behaviour and access can move without notice. For the second case, Begin.sh takes a prompt or a URL and hands you a working static site or Expo app as a zip, with nothing to install first.
