Google tests Gemini 4 internally, with attention on Carbon's coding
What happened
On October 10, The Decoder reported that Google is testing three Gemini 4 variants internally: Argon, Barium and Carbon. Carbon has been deployed to Google's internal coding platform Jetski. Some employees put Carbon's coding ability on par with Opus 5.5, Anthropic's strongest coding model. The report also says more testing is needed. Claims about Carbon's coding performance come from internal employee assessments, and the report does not provide test results sufficient to confirm the two are comparable.
