Google Developers Blog·medium signal

Google announced that Gemini CLI and Gemini Code Assist IDE extensions will stop serving requests for Google AI Pro, Ultra, and free-tier users on June 18, 2026. The replacement Antigravity CLI, built in Go, shares the same agent harness as Antigravity 2.0 with cross-platform terminal sandboxing, credential masking, and hardened Git policies. Developers using Gemini CLI in their workflows have less than 4 weeks to migrate — a significant forcing function for the entire Gemini developer ecosystem.
