Google Antigravity CLI adds queue control and more reliable remote sessions

Google’s Antigravity CLI has shipped a set of September updates focused on model control, headless execution, and long-running remote sessions. The official changelog lists versions 1.1.27 and 1.1.28 on September 5 and September 9, followed by a September 10 release that adds persistent remote-control service management.

Remote control can run as a background service

The September 10 release adds service-manager subcommands for remote control, allowing the CLI to run the remote-control service as a persistent background daemon. The same release broadens half-page scrolling and keybindings and fixes issues involving content filters, scratch-directory watchers, plugin MCP initialization, schema validation, and conversation resumption.

A background service can make a remote agent easier to reach, but it also creates a durable process with access to the configured workspace. Teams should review which user starts it, which network interfaces it exposes, and how the service is stopped before using it on shared or production machines.

More resilient headless and model workflows

Version 1.1.28 improves retry behavior for transient model API errors with extended exponential backoff. It also speeds startup and sign-in by reading cached credentials, streamlines headless execution and error reporting, and makes tool approval prompts more useful by including contextual action descriptions and reasons.

Version 1.1.27 adds mid-conversation model execution through /model, supports custom-agent subagent dependencies, and fixes MCP parameter validation. Earlier September releases add workspace-grouped /resume navigation, Gemini 3.8 Flash to the model catalog for GEMINI_API_KEY users, comments and trailing commas in mcp_config.json, and cleaner headless stream shutdown.

Practical upgrade notes

The updates are CLI changes rather than a new Antigravity desktop release. The changelog groups them with fixes for plugin reinstalls, plugin MCP working directories, subagent lifecycle states, command memory leaks, and Windows skill paths. Check the installed CLI version and test model selection, approval prompts, MCP configuration, remote-control lifecycle, and non-interactive exit behavior in the environments where the CLI runs.

September 22 follow-up: CLI 1.2.8

Antigravity CLI 1.2.8 adds proportional context-compaction budgets across prompts and sizes truncation ceilings from the model’s full context window. It also enables default PDF and audio support for custom models, makes Ctrl+G launch a real terminal with stdout, caps voice-dictation recordings to avoid deadline failures, and fixes resource and memory leaks across conversations and background pollers.

These are reliability and context-management changes rather than a new agent surface. Pin the CLI in automation and verify compaction, custom-model media inputs, terminal launch behavior, voice dictation, and long-running memory use before upgrading shared runners.

September 27 follow-up: CLI 1.2.12

The Antigravity docs list CLI 1.2.12 on September 27. Full-screen scrolling now coalesces bursts of mouse-wheel or trackpad input before redrawing, reducing CPU use and lag in long conversations and the artifact viewer. For GEMINI_API_KEY sessions, the CLI also stops promptly when the API reports an exhausted daily quota, project or billing spend cap, or depleted prepaid credits; short-lived per-minute limits still retry.

Latest CLI changelog: version 1.2.14

The latest entry in the official CLI changelog documents 1.2.14 and adds Queued Messages to /config. The default Queue behavior holds follow-up messages until the current turn ends; Send Immediately interrupts the agent with those messages. The same option can be set with "queuedMessages": "send-immediately" in settings.json; the changelog notes that this setting was previously ignored.

The 1.2.14 entry also improves remote-control start in Linux environments without a systemd user service manager: it starts a background process and warns that it will not restart after a crash or start at boot. remote-control status shows the process ID, and remote-control stop shuts it down. Long conversations resume faster because the CLI no longer scans every step up front.

The changelog does not give a separate release date for 1.2.14. Verify the installed version and test queue behavior, quota handling, and remote-control lifecycle before upgrading shared runners.
