For coding, qwen 3.6 35b a3b solved 11/98 of the Power Ranking tasks (best-of-two), compared to 10/98 for the same size qwen 3.5. So it's at best very slightly improved and not at all in the class of qwen 3.5 27b dense (26 solved) let alone opus (95/98 solved, for 4.6).
If all models are trained on the benchmark data, you cannot extrapolate the benchmark scores to performance on unseen data, but the ranking of different models still tells you something. A model that solves 95/98 benchmark problems may turn out much worse than that in real life, but probably not much worse than the one that only solved 11/98 despite training on the benchmark problems.
This doesn't hold if some models trained on the benchmark and some didn't, but you can fix this by deliberately fine-tuning all models for the benchmark before comparing them. For more in-depth discussion of this, see https://mlbenchmarks.org/11-evaluating-language-models.html#...
I've been using Qwen 3.5 35B-A3B with images as input so I suspect you perhaps didn't include the vision part of the model during testing (I use llama.cpp and I learned I needed to include the separate mmproj part).
You compare tiny modal for local inference vs propertiary, expensive frontier model. It would be more fair to compare against similar priced model or tiny frontier models like haiku, flash or gpt nano.
