A faster, cheaper-per-turn Gemini 4 frontier model for coding and agent work, and Google’s recommended everyday choice. It has a 1M tokens context window. Through Google’s API it costs $2.00 (then $4.00 from Dec 1) per million input tokens and $10.00 (then $20.00 from Dec 1) per million output tokens.
Among the tools we track, it’s available in Antigravity CLI, Copilot, Cursor, Zed and Amp. It opened to developers globally on October 13, 2026. Gemini CLI says it isn’t optimised for Gemini 4 models, so Google points Argon users to Antigravity CLI.
