Gemini CLI Dies Today... Meet Antigravity CLI

TL;DR
Google has sunset Gemini CLI and replaced it with Antigravity CLI (agy), a closed-source command-line AI coding tool that supports not just Gemini models but also Claude and GPT models. The creator demos Antigravity, warns about its very limited free quota, and showcases his community-built multi-agent framework called Tank that orchestrates Antigravity, Claude Code, Codex, and Grok together.
Key points
1
Gemini CLI has been killed as of the Google IO 2026 conference and replaced by Antigravity CLI, installed with a single command and invoked as 'agy' in the terminal
2
Antigravity CLI is now closed-source, unlike the open-source Gemini CLI, with the GitHub repo containing only a README, changelog, and a GIF
3
Antigravity supports multiple model providers including Gemini 2.5 Flash, Gemini 2.1 Pro, Claude Sonnet, Claude Opus 4.6, and GPT models via the free Google OAuth login
4
The free tier quota is extremely limited — the creator burned through it building a simple Snake game and found the reset timer was approximately 150 hours (over 6 days)
5
The creator's Tank framework (available to community members) now integrates Antigravity alongside Claude Code, Codex, and Grok, with Apple Watch-style usage rings and scheduled AI tasks
Actionable insights
→
Install Antigravity CLI with a single terminal command and authenticate via Google OAuth for free access — but budget usage carefully as the free quota resets only every ~150 hours
→
Use 'agy /model' inside Antigravity to browse available models including Claude Opus 4.6 and GPT variants — a useful workaround if you need those models without separate subscriptions
→
For serious coding workloads, connect Antigravity through a Google Cloud project instead of OAuth for a more stable, higher-quota experience
→
If running multiple AI agents simultaneously, use branch isolation in your project so agents do not overwrite each other's work
→
Anthropic confirmed that programmatic Claude Code CLI usage does not bill against the API bucket, meaning scheduled Claude Code tasks can run on a Claude Max subscription without extra API charges
Notable quotes
“Google, that it's closed source and no longer open source... there is no source code. This is completely closed. This is a new direction from the Gemini CLI that was very much open and ready for use.”
“I just burned through my quota like building a simple snake game in Antigravity. So yeah, unless you're actually going to use this via a Google Cloud project, you get like literally two or three prompts like per week, which is nothing.”
“The creator of Claude Code said, I don't write prompts anymore. I write loops.”
