A more capable Carbon hiding behind Argon? Testers share new 3D outputs.
A 1 November cow-modelling comparison adds a concrete example to the Carbon-H routing claim. It does not identify the model behind Arena.
@leo114119 shared a 3D cow comparison on 1 November, attributing one result to Gemini 4 Carbon and the other to Gemini 4 Argon. The author describes a shift from block-based assembly to more varied rounded and pointed shapes. It gives the newer-model discussion a specific task to examine.
The identity claim goes further back: @Waguri_Kaoruko8 wrote on 31 October that Carbon-H was being tested on Arena as Argon 4 and felt faster and better at coding, design and 3D. @testingcatalog amplified that account on 1 November. That repetition is one reporting chain, not independent confirmation of the hidden model.
More expressive geometry from code would matter for procedural scenes and quick prototypes. But these posts do not give us a reproducible, matched-settings comparison or a verified backend identity. Treat the examples as a reason to investigate an apparent capability change, not proof of a general quality lead.
