Grok Bot’s computer guide, updated October 9, says every Bot on one account uses the same cloud computer. Files, browser cookies, signed-in sessions and command-line credentials are shared. Each Bot has its own screen for parallel work, but those screens are not security boundaries. Signing into a website for one Bot makes that session available to the others.
The overview draws a narrower distinction for conversational context: conversations and learned context remain separate per Bot, while files and direct handoffs can move information between them. It also says different users are isolated. Taken together, the documents describe separation between accounts alongside substantial sharing within an account. This is an analysis of the published operating model, not a report of a breach or a newly shipped isolation feature.
Editorial take: Assigning one Bot to finance and another to marketing is an organizational choice, not a reliable way to wall off their computer access. Before placing sensitive material in the shared environment, decide whether every Bot in that account should be able to use it. Project folders can keep work tidy; they should not be mistaken for an access-control system.
