Fwiw - I did a fairly large comparison of Gemini Nano (the in browser ai model) vs a comparable free hosted model of Gemma (from OpenRouter) and the hosted model absolutely trashed the local model on every aspect of speed, reliability, availability, etc. [1]
I'm not particularly happy about that outcome as I wish we had more locally run AI models for reasons of privacy and efficiency, so this is more just a warning that at present there are some severe tradeoffs.
