Yes they are, but you should understand what is the defining feature of a local model. Being able to run them locally is a consequence of that defining feature, not the defining feature. And it turns out that it makes them cheaper to run.

Moreover, you can run both local models and non-local open weights models through providers such as OpenRouter. They evem have Qwen2.5 7B.

> Also, open-weights models are more expensive per task than Haiku and Luna

You should really check your notes. Luna only remained competitive because OpenAI was forced to halve its cost just to avoid being dominated by open weight models. I seriously recommend you check out OpenRouter's benchmarks.
