Anonymous Arena model, suspected to be Gemini 4 Pro, beats GPT-6 Astra on 3D jet engine prompt
The same prompt for an interactive 3D jet engine cutaway produced a far more detailed result from an anonymous Arena model, which the community suspects is Gemini 4 Pro, though Google has not confirmed it.
A new model showed up on Arena and it hits hard. The community believes it is Gemini 4 Pro. Google has not confirmed that. The same prompt was run against GPT-6 Astra, and the two builds sit side by side in this clip. The prompt: an interactive 3D jet engine with a cutaway view, x-ray mode and airflow. It's a brutal test, because dozens of parts, internal geometry and moving air all have to hold together in one scene. Gemini's build looks ridiculously strong. The level of detail is another tier. One caveat: this is a single prompt and a first impression, not a benchmark. Arena outputs vary from run to run, and there is no public model card yet. Still, GPT-6 Astra only launched this month. If this really is Gemini 4 Pro, Google just made the frontier race a three-way fight again. https://x.com/YouWareAI/status/2101271938706685991/video/1
