GOOGLE MIGHT ALREADY BE TESTING WHAT COMES AFTER GEMINI 4 ARGON 💀 Google is reportedly testing a new internal checkpoint called Carbon.... And the wild part ??? Employees testing it say its coding feels close to Claude Opus 5.5 But there’s no public benchmark proving Carbon beats Anthropic yet Even crazier… Argon itself reportedly came from an older checkpoint called Barium-B So while we’re still comparing Argon vs Opus… Google might already be testing what comes next 💀 Would you try Carbon if Google released it? 👀
