Antigravity CLI is now live; Gemini CLI reaches end of life

Gemini CLI

As of June 18, 2026, Gemini CLI officially stopped serving requests for free users, Google AI Pro subscribers, and Google AI Ultra subscribers, completing the transition announced at Google I/O in May. Antigravity CLI is the active replacement: a Go-based terminal agent powered by Gemini 3.5 Flash by default, with asynchronous parallel subagents, native OS sandboxing (nsjail, sandbox-exec, AppContainer), and shared infrastructure with the Antigravity 2.0 desktop app. All core Gemini CLI capabilities (Agent Skills, Hooks, Subagents, and Extensions, now Antigravity plugins) carry over. Enterprise customers with Gemini Code Assist Standard or Enterprise licenses retain access via Google Cloud and are unaffected.


Gemini CLI stops serving requests

The cutoff is now in effect. As of June 18, 2026, Gemini CLI no longer serves requests for free-tier users, Google AI Pro subscribers, or Google AI Ultra subscribers. The same date also ends access for Gemini Code Assist for individuals and the associated IDE extensions. This completes the transition Google first announced at Google I/O in May 2026, when it confirmed it was consolidating its terminal tooling around a single agent platform.

The shutdown is a hard cutoff, not a gradual wind-down. Any shell script, CI/CD pipeline, or automation that still invokes the legacy gemini command will stop working from this date. Teams that depended on the open-source Apache 2.0 tool need to migrate now rather than later.

What Antigravity CLI is

Antigravity CLI is the official replacement. It is a Go-based terminal agent, rewritten for speed and responsiveness, that ships inside the broader Antigravity 2.0 platform and shares the same agent harness as the Antigravity 2.0 desktop app. By default it runs on Gemini 3.5 Flash, the model Google co-developed using Antigravity itself.

Key upgrades over Gemini CLI

The headline addition is asynchronous, parallel subagents. From inside the TUI you can dispatch a long-running task to a background agent and keep prompting in the foreground, and you can run several agents at once, which is useful for splitting a large refactor across packages. Antigravity CLI also adds native OS sandboxing for tool execution, using nsjail on Linux, sandbox-exec on macOS, and AppContainer on Windows.

Capability carryover

Google designed the migration to preserve the workflows developers already rely on. All core Gemini CLI capabilities carry over: Agent Skills, Hooks, and Subagents move across directly, and Extensions continue to work, now repackaged as Antigravity plugins. Configuration such as hooks is shared between the TUI and the backend, so existing setups translate with minimal rework. Google has published migration documentation to support the switch.

Enterprise exemption

Not everyone is affected. Customers on a Gemini Code Assist Standard or Enterprise license retain access through Google Cloud and are unaffected by the June 18 cutoff. These organizations can continue using their existing tooling with ongoing model updates, so the end-of-life applies to consumer and individual tiers, not to paid enterprise agreements.
