Gemini 4 Carbon lands in AI Mode, limited to $99.99 Ultra tier
· 26h ago · Originally reported by PPC Land
Google's Gemini 4 Carbon model is rolling out to AI Mode, but only for subscribers on the $99.99 Ultra plan. Developers face Argon-tier pricing of $2 per million input tokens and $10 per million output tokens, though Carbon's reasoning uses more tokens per task. The open question is whether end tasks end up costing more than on Argon.
Why it matters
Token-hungry reasoning models can quietly raise the cost of AI-powered search and ad features, which flows into how advertisers buy and measure AI-driven placements. Pricing tiers also signal who gets access to the newest AI surfaces first.
Explain it like I’m new here
It's like a fancier engine that burns more gas per trip — the per-gallon price looks the same, but the ride costs more.
