Where are small Models like Qwen3 0.6B and Qwen3.5 0.8B used ? Huggingface shows 2.88 million downloads this month.[D]

I can see 2.88M downloads per month for small Qwen3.5 model. I tried using earlier model 0.6B in a deep resarch workflow and it was very difficult to get something done with this model. Firstly they have a very surface level understanding of concepts. Poor Semantic understand means they can get confused about the topic or the task. Json outputs are often broken. Adding a layer of checks on top took much of my time while working with these models. Slow resposne.
