Google is said to be testing a Gemini 4 version that rivals Claude.
Business Insider reports, without confirmation from Google, that staff are testing a Gemini 4 version called Carbon. One tester said its coding felt comparable to Opus 5.5, an Anthropic model. Google has confirmed nothing about Carbon, and nobody outside the company can test the claim.
Why it mattersIf the report holds, Google's coding tools could catch up with the model many developers prefer. Until Google ships something, treat it as office talk.
