Google makes Gemini 4 Carbon generally available at Argon's price ($2/$10 intro, $4/$20 from Dec 1); claims #1 on CursorBench 4.0 and two other agent benchmarks

Why it matters

【Key points】

· Nov 10, 2026: Google makes Gemini 4 Carbon (gemini-4-carbon) generally available. Since Oct 28 it had been open only to cyber defenders via the Fairwind Program.

• · Price per 1M tokens: $2 input / $10 output through Nov 30, then $4 / $20 from Dec 1.
• Argon is priced the same.
• There is no free tier.

· Specs: 1M-token context, up to 65K / 1M output tokens, and text, image, audio, video and PDF input.

· Benchmarks (Google's figures): #1 on CursorBench 4.0, WANDR and AutomationBench at less than half the cost per task of the next-best external model. #2 on the new MKA benchmark at about 1/6 the cost of the leader.

· Safety: 0.8% per-attempt breach rate in simulated cyberattacks (Argon: 3.1%). 92% on a 375-task agentic honesty benchmark (Argon: 70%).

【Our read】

· Background: this follows Carbon's limited debut (e/1063) and mirrors Argon's GA (e/843). AlphaProof Code (e/1100) ran on Carbon.

• · Comparison: even at $4 / $20, Carbon's list price is half that of Claude Fable 5.2 (e/1097, $8 / $40).
• Carbon uses more thinking tokens, though, so real cost per task depends on the workload.
• Most of the cited leaderboards are partner-run or new.

· Impact: pricing the flagship the same as the workhorse shifts competition toward cost per task. Things to watch: usage after Dec 1, and independent re-tests of the GA model.
