Pricing: As of 2026-06-18 the free Code Assist for individuals tier and Google AI Pro/Ultra access ended; Gemini CLI continues with paid Gemini/Vertex API keys (pay as you go) and Gemini Code Assist Standard/Enterprise licenses (1,500/2,000 requests per user per day per the quota docs). Antigravity CLI is free to everyone.
