samcharrington · x · 2026-11-12
Sam Charrington's recap details Gemini 4's new naming: Pro/Flash are gone, replaced by element names. Argon is the efficient default; Carbon thinks harder and costs more than Argon but Google claims 2x lower cost per task than the next-best external model. The benchmark chart shows Gemini 4 Carbon leading GPT-6 Astra and Claude Opus 5.5 on AA Index v5.0 (59), SWE-sweep (9.6%), Terminal-Bench 4.0 (65.2%), AutomationBench (53.9%), and GraphWalks (96.2%).
