Gemini 4 Carbon hands-on: better 3D but slow
A reviewer finds Gemini 4 Carbon beats Argon at 3D and game understanding but is slower and weaker at frontend, still behind Opus 5.5 and Astra at 3D.

Gemini 4 Carbon: My Impressions/Review - Gemini 4 Argon is on LMArena under the codename "gemini-4-argon". - Google launched two checkpoints, and I tested both. - Gemini 4 Carbon is quite good at 3D now and has a better understanding of how to create games compared to Gemini 4 Argon. - But I would say Opus 5.5 and Astra are still better at 3D. - Its slower compared to Argon, Opus, and others. They should fix this. - Its frontend skills are also not that good. From my testing, it seems they are focusing more on 3D. Now waiting for the next checkpoint.
