I am absolutely pro local and true open source models.

Personally I haven't seen any productivity gain since Opus 4.5 times.

But: I can't fully get behind the opinion that (so called) "open source models" are simply superior and will be in the future, because when I asked some models who they are, they answered with "I am Claude from Anthropic", which could mean they have been trained by exfiltrating Claude.

I have NO moral objection to this, as Anthropic and "Open""AI".also trained their models on anything they could get their hands on.

It's more about the question: can and will these models be updated, even if Anthropic et al fail. Who's gonna pay for training then? What's their incentive? Have we reached a plateau?
