Gemini 4 Hydrogen’s new seaplane looks much better

Hydrogen’s latest seaplane is a big step up in style. The interface is cleaner, and the whole scene looks much closer to what I liked about Argon. When I posted the clip, I called it on par. That’s the one I’d open first. 1

I’ve been waiting for a new Flash-tier model for a while. What has made these tests exciting is seeing this kind of 3D output arrive quickly enough that trying another idea feels easy. The early helicopter and seaplane were already interesting. This newer seaplane looks much more like something I’d want to keep working on.

A quick note on the name: we’ve been calling these Arena tests Gemini 4 Hydrogen. In the original pagoda test, Arena displayed Gemini 3.8 Flash. Our attribution isn’t independent confirmation of a released Google model or API identifier, so these clips stay separate from identity-matched benchmark scores. 5

The new pagoda is cleaner, with a trade-off

The pagoda shows the change in interface nicely. It gets out of the way more than before. I’m less sure about the scene itself: my first impression was that it had lost some detail. A tidier UI is welcome, but I still want the model to put the work into the thing I asked it to build. 2

The engine has a lot to play with

The V12 is from the earlier set of tests. It includes assembly and exploded views alongside X-ray and wireframe options. Those are useful ways to explore a generated model, and they make the output more interesting than a single good render. 3

The speed is the part I keep noticing

Drone Racers took around a minute or two in our test. That’s the timing I reported when I posted it. Even so, getting a result like this back that quickly makes me want to try more things. 4

You can watch the F1 car, helicopter, earlier seaplane and voxel-world demo in the full library. For now, the latest seaplane is the strongest reason I have to keep an eye on Hydrogen. I’d like to see that cleaner style carry through to the other prompts too.
