Local Qwen 3.6 vs frontier models on a coding primitive: single-file HTML canvas driving animation - results and GIFs

Saw this post comparing Qwen 3.6 variants on coding primitives, so I wanted to see how local quants stack up against frontier models on a similar dense, single-file coding task. I ran the exact same prompt across local and web-based models accessed through my Perplexity subscription. The prompt "Wri
