Gemini 4 Argon just landed on OpenCode Go, and the offer is actually pretty amazing. For $10 a month you get around $60 worth of Argon usage, at least until November 30. which is when Google plans to double its API price to $4/$20. So right now, a $10 plan gives you more Argon than most people will get anywhere else. even Antigravity requires an Ultra plan for $99. If you've been curious about Argon, this is probably the cheapest window you'll get.
