Google reportedly tests Gemini 4 checkpoint Carbon internally
Business Insider reports that Google staff are testing a Gemini 4 checkpoint codenamed Carbon, with coding said to feel comparable to Opus 5.5, while the announced Argon is still unavailable to regular users.

GOOGLE HAS A GEMINI THAT REPORTEDLY CODES LIKE OPUS 5.5. AND YOU CAN'T USE IT 🚨 Business Insider says Google staff are testing a new Gemini 4 checkpoint internally, codename Carbon. one dev said coding feels comparable to Opus 5.5 but here's the weird part Gemini 4 Argon got announced with huge benchmark numbers. regular users still can't touch it. and Google's own people reportedly say it's less convincing on real work than on benchmarks so right now Google has a model that's announced but not shipped, and a better one already being tested behind it honestly this doesn't look like Google is behind on research. it looks like Google can't ship fast enough meanwhile Anthropic and OpenAI drop something and you're using it the same afternoon and some reports say employees credit Carbon's jump to recursive self-improvement. if that part is real it's the actual headline lol would you switch from Opus if Carbon drops next week?
