Opus 5.5 vs Sonnet 5.5 : 3D steampunk whale modeling

I've seen a couple cool demos on twitter of people making detailed robots/mechs and wanted to try making something like that for myself and while I was making the scene with opus, antrhopic decided to drop the new sonnet, so I had to test that one too, since the benchmarks were off the charts for it |Metric|Opus 5.5|Sonnet 5.5| |:-|:-|:-| |Output tokens|2.50M|1.68M| |Total tokens (incl. cache)|342M|297M| |API equivalent|\~$156|\~$109| the work wasn't done in one prompt, but in a series of structured prompts(same for both models though), the whales were made in blender and then transferred into three.js to run in the browser sonnet 5.5 did surprise me here, but it's still pretty far from opus 5 I would say, to be fair the benchmarks claim nothing about 3D, so I guess it's to be expected setup: both claude models via sub and blendermcp inside [atomic.chat](http://atomic.chat)
