I recently tried Qwen, alibaba’s proposal for AI implementaion, and it works really well at coding. Comparison between Claude design and Qwen Studio is in favour of Qwen when asked to perform background threejs design with scroll based animations on text. But time is not unlimited. Time you spend using one engine teaches a lot. Claude Opus 5 has the capacity to choose specific skillset when answering complex coding problem. In my example of building a statistics viewer, it went for dataviz skillset.
