Qwen isn't a good tiny model, it's scaled down and leads to bad results. It'll output the name of a capital city, but then it falls down on real work. MiniCPM, LFM, K2, Granite, Nemotron Nano, Gemma E2B, are designed to do work at tiny size. Speed means nothing if it gets stuck in doom loops, can't tool call, isn't trained on embedded functionality, etc. (https://artificialanalysis.ai/models/open-source/tiny)
