Google announced it will retire Gemini CLI in favor of Antigravity CLI, a new terminal interface built for multi-agent workflows. The shift responds to user feedback showing developers now need coordinated agent systems rather than single-agent tools. Gemini CLI, launched in 2025, gained over 100,000 GitHub stars and 6,000 merged pull requests from its community.

Antigravity CLI introduces several technical upgrades: written in Go for faster execution, supports asynchronous multi-agent orchestration, and shares a unified backend with the Antigravity desktop application. The new system maintains core features like Agent Skills, Hooks, and Subagents while enabling complex background tasks without terminal lockup. Users can perform large-scale refactors and parallel research through coordinated agent workflows.

The transition timeline sets June 18, 2026 as the cutoff date when Gemini CLI will stop serving requests for consumer Google AI accounts. Enterprise customers retain access through paid API keys, while individual users must migrate to the new platform. Google provides technical documentation and upcoming video walkthroughs to facilitate the shift.
