Google’s next-generation large model is ready to be launched. According to foreign media reports, Google is set to officially release the new Gemini4 “Argon” model to the public. Meanwhile, its internal staff are actively testing more powerful subsequent versions, aiming to narrow the technical gap with leading competitors in the industry through continuous technological improvements.
According to the exposed internal documents and screenshots, Google employees have been testing a new version codenamed “Carbon” recently. This model is likely a new checkpoint update under the Argon architecture, and it has successfully been integrated into Google’s internal code platform, Jetski, in recent days. Internal test feedback indicates that Carbon performs remarkably well in code writing and processing capabilities; some employees even said its performance is “comparable to Opus5.5” – a top-tier model developed by Anthropic for long-term tasks involving complex code agents. However, the team also emphasized that this excellent conclusion still needs more in-depth evaluation to be ultimately verified.
Looking back at the development process of the Gemini4 series, the early version of Argon also received generally positive reviews during internal tests. Some employees noted that the early version was still somewhat challenging when handling some high-difficulty programming tasks, and its performance was roughly equivalent to that of Claude Opus5 released by Anthropic previously. Currently, Google has conducted comprehensive testing on several Gemini4 derivative models with codenames including Argon, Barium, and Carbon.
It should be noted that the internal codes used by tech giants for their products often do not exactly correspond to the official names that are eventually released to the public. For example, internal documents indicate that the model that was previously determined to be released under the name “Argon” actually had an internal code of “Barium-B”. Therefore, it is still unclear whether the highly anticipated Carbon will be released as a refined version of Argon, or as a new independent model under the Gemini4 family. In the face of external attention, Google’s official team remains silent and refuses to make any comments.
