Antigravity 2.0: Google replaces its Gemini CLI with a Go-built agent platform
AnalysisGoogle launched Antigravity 2.0 at I/O on May 19: a new CLI written in Go (faster and replacing the Gemini CLI outright), a revamped desktop app that can orchestrate multiple parallel subagent workflows, and an SDK for custom agents. Gemini Spark, a persistent agent that runs on dedicated Google Cloud VMs and maintains state between sessions, entered beta for AI Pro and Ultra subscribers. Pricing changed: the existing $250/month AI Ultra plan drops to $200, and a new $100/month tier with 5x the Pro limits was added. Google is asking all current Gemini CLI users to migrate to Antigravity CLI.
