Google's next-generation large model is about to be launched. According to foreign media reports, Google is about to officially release its next-generation Gemini4 "Argon" model to the public. At the same time, internal employees have been actively testing a more powerful subsequent iteration version, trying to further narrow the technical gap with industry-leading competitors through continuous technological iterations.

According to 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 has been successfully integrated into Google's internal code platform Jetski. Internal test feedback shows that Carbon has attracted attention for its performance in code writing and processing capabilities. Some employees even mentioned that its performance is "comparable to Opus5.5" — that is, a top-tier model developed by Anthropic for long-term complex code intelligent agents. However, the team also emphasized that this outstanding conclusion still needs further evaluation to be finally verified.

Looking back at the development history of the Gemini4 series, the early version of Argon also received generally positive reviews during internal testing. Some employees pointed out that the early version still had some difficulties in handling certain high-level programming tasks, and its level was roughly equivalent to the previously released Claude Opus5 by Anthropic. Currently, Google has conducted comprehensive tests on multiple Gemini4 derivative models with codenames including Argon, Barium, and Carbon.

It should be noted that the internal codenames of tech giants' products often do not fully correspond to their officially released names. For example, internal documents show that the model previously released under the name "Argon" had an initial internal codename of "Barium-B." Therefore, it remains uncertain whether the highly anticipated Carbon will be released as a follow-up fine-tuned version of Argon or as an independent new model in the Gemini4 family. In response to external attention, Google's official side remains silent and has refused to make any comments.
