# Antigravity preview

A powerful general-purpose managed agent designed for autonomous, multi-step
workflows. This model plans, reasons, runs code, manages files, and searches the
web inside a secure, isolated Linux sandbox hosted by Google.

The September 2026 release (`antigravity-preview-09-2026`) upgrades the runtime
harness with improved prompt caching, native code search tools, and efficient
line-range file editing.
