Gemini 4 Argon launches on Pro/Ultra and API with limited-time pricing
Argon is available to Pro/Ultra subscribers and via API at $2 per million input tokens and $10 per million output until November 30, doubling after that, with the output limit raised to 1M tokens.
google shipped gemini 4 argon yesterday to pro and ultra subscribers, plus the api the price is the headline. $2 per million input tokens, $10 per million output, until november 30. on december 1 it doubles the part i liked more: google let argon agents loose on a rust port of their av1 video decoder. they replaced 32k lines of hand-written simd code with safe rust and made it 2.7x faster, same output output limit goes from 64k to 1m tokens. small catch, that 1m is shared with your input, and you need background mode to go past the default "beats gpt-6 astra, fable 5.1 and opus 5.5" is mostly google's own table. it wins most rows, but it's last on frontierswe and terminal-bench, the two that look most like real coding work on the arena agent leaderboard it sits at #5. at $0.79 per task vs $5.59 for opus 5.5 at #1 not the smartest model. maybe the best deal for the next 6 weeks
