If a `gemini` command in your terminal, CI pipeline, or shell script suddenly stopped working after June 18, 2026, this is why: Google retired the hosted Gemini CLI experience for individual Google AI Pro, Ultra, and free-tier accounts on that date, as part of consolidating its developer tooling under a single new brand, Antigravity. The open-source repository itself isn't archived and still technically works with your own Gemini API key, but Google's active development, and the terminal experience most people actually used, has moved to a new tool: Antigravity CLI.
What actually happened
At Google I/O on May 19, 2026, Google announced it was consolidating its AI developer tools — Gemini CLI and the Gemini Code Assist IDE extensions included — under the Antigravity brand. On June 18, 2026, the transition took effect: Gemini CLI stopped serving requests for Google AI Pro, Google AI Ultra, and free individual accounts, with no grace period for anything still depending on it. Enterprise users authenticating with Gemini Code Assist licenses or their own API keys were unaffected by the cutoff — it specifically hit the consumer-facing hosted service, not API-based usage.
What replaced it
Antigravity CLI is the new terminal experience, rewritten in Go for speed and built with multiple simultaneous agents in mind, sharing its underlying architecture with the broader Antigravity 2.0 desktop app. Google demoed its capability at I/O 2026 with a genuinely striking example: an orchestrated set of parallel agents building a working operating-system core from scratch — including running a Doom clone on top of it — for under $1,000 in total token cost. Antigravity CLI supports asynchronous background workflows, meaning you can kick off a longer task and have it continue running without holding your terminal session open.
If your workflow broke, here's what to actually do
If you were using Gemini CLI interactively as an individual developer: migrate to Antigravity CLI directly — it's the intended successor and free tier access is available, though the daily request allowance is meaningfully smaller than what Gemini CLI's free tier originally offered.
If you had a CI/CD pipeline, shell script, or automation calling the `gemini` command: that stopped working on June 18 with no grace period, so this needs an immediate fix, not a "when I get to it" one. Either migrate the calling code to Antigravity CLI's command syntax, or switch to direct Gemini API key authentication if you specifically need to keep calling Gemini models without adopting the new CLI tool.
If you're an Enterprise user on a Gemini Code Assist license: you were unaffected by this cutoff and can continue as-is, though it's worth confirming your organization's migration timeline directly with Google, since consolidation efforts like this typically continue beyond the initial consumer-facing cutoff.
Should you actually switch to Antigravity CLI, or use something else?
If you're specifically invested in Google's model lineup (Gemini) for terminal-based coding work, Antigravity CLI is the direct, actively-developed path forward — there's no real reason to stay on the deprecated Gemini CLI given the hosted service is already gone for individual accounts. If you're choosing a terminal coding agent fresh rather than migrating, it's worth comparing against Claude Code (Anthropic's terminal-native agent, from $20/month) and OpenAI Codex (OpenAI's CLI, SDK, and IDE bundle, also from $20/month) — both remain stable, actively maintained options that haven't gone through a comparable disruptive migration in 2026.
FAQ
Is the Gemini CLI GitHub repository archived? No — the repository itself remains open and shows active commits and issue activity; what changed is that Google stopped serving hosted requests to individual Pro, Ultra, and free-tier accounts through it, and shifted development focus to Antigravity CLI.
Can I keep using Gemini CLI if I bring my own API key? The retirement specifically targeted the hosted service tied to individual Google AI subscription accounts; API-key-based authentication was reported as unaffected, but confirm current behavior directly against Google's developer documentation before relying on this for anything important, since migration details can continue to shift.
Is Antigravity CLI free to use? It has a free tier, but multiple sources report it's meaningfully more restrictive than Gemini CLI's original free allowance — check Google's current published limits before assuming parity with what you had before.
Did this affect the Gemini Code Assist IDE extension too? Yes — the same May 2026 announcement covered retiring the standalone Gemini Code Assist IDE extensions alongside Gemini CLI, as part of the same consolidation under Antigravity.
