What model do you propose that is close enough to chatgpt or Claude so people will actually use it for their work?

I am not up to date with the models, but I have heard good stories about a couple of open source models. You should ask Simon Willis. I hope he will be summoned (@simonw).

It was my point that currently the best open weight models are from China, so not usable in the EU.

But of course the world changes so rapidly that what is now is irrelevant tomorrow.
