Scoop: a manifest is staged in the desktop source repository; use the verified release installers until a public bucket is available.
Obtainium / APK updaters: point at the GitHub Mobile release or the APK URL above.
Browser automation: the permission-gated Browser Pilot is built into ZERO ONE 7.9.2, so no extension is required. For ordinary Chrome / Brave tabs, the OpenZero Tab Pilot companion remains optional and user-installed.
Desktop 7.9.2 uses OpenZero Gemma4 E2B Agentic for local Assistant chat while the separate Ministral 8B Runtime Agent remains full OpenZero’s default. Model weights download separately; local chat cannot execute tools by itself. Live status JSON · Mobile checksums · Desktop checksums
