> I completely disagree with this. What you are saying is that performance, all they need a simple trick and they get Claude performance for free. In that case, why do we see open weight models still lagging?

Yes, they are lagging.

But "performance of Claude's from 6 months behind" is fine for a lot of tasks. And the performance of today's Claude will be still useful for many (and more and more) tasks in 6 months.

The frontier labs are making models for smaller and smaller share of the pie, as the capabilities of open models grow. That isn't sustainable
